State Warning
According to state law, California requires that firearm
manufacturers, distributors and retailers include
conspicuous, specific warnings with firearms sold in
that state.
Warning: You are reSponSible
for firearmS SafetY
FAILURE TO FOLLOW ANY OF THE FOLLOWING
WARNINGS COULD RESULT IN SERIOUS INJURY
OR DEATH.
As a firearm owner, you accept a set of demanding
responsibilities. How seriously you take these
responsibilities can be the difference between life
and death.
There is no excuse for careless or abusive handling of
any firearm. At all times handle this firearm and all
other firearms with intense respect for their power and
potential danger.
Please read and understand all of the cautions, warnings,
notices, proper handling procedures and instructions
outlined in this owner’s manual before using your
new firearm.
1 ALWAYS KEEP THE MUZZLE OF YOUR FIREARM
POINTED IN A SAFE DIRECTION EVEN THOUGH
YOU ARE CERTAIN IT IS UNLOADED.
Never point any firearm at anything you do not intend
to shoot. Be extremely alert and aware of all persons
and property within the range of your ammunition.
2 NEVER RELY TOTALLY ON YOUR FIREARM’S
MECHANICAL “SAFETY” DEVICE. LIKE ANY
MECHANICAL DEVICE, A “SAFETY” CAN SOMETIMES
FAIL; IT CAN BE JARRED OR INADVERTENTLY
MANIPULATED INTO AN UNSAFE CONDITION.
The word “safety” describes a firearm’s trigger block
mechanism, sear block mechanism, hammer block
mechanism or firing pin block mechanism. Mechanical
“safeties” are designed to place your firearm in a safer
status, and no guarantee can be made that the firearm
1
will not fire even if the “safety” is in the on safe
position. Mechanical “safeties” merely aid safe gun
handling and are no excuse for pointing your firearm’s
muzzle in an unsafe direction. See “Operation of the
‘Safety’” on pages 11-12 for instructions on the
operation of this firearm’s “safety.”
Remember, safe gun handling does not stop with your
firearm’s mechanical “safety” devices, it starts there.
Always treat this firearm with the respect due a
loaded, ready-to-fire firearm.
Some firearms do not have a mechanical “safety.”
Many target firearms, lever-action firearms and pistols
do not have manual “safety” mechanisms. Therefore it
is critical to read and understand the owner’s manual
for every firearm which explains the safe operation of
the firearm.
While it is a good idea to test your firearm’s
mechanical “safety” periodically for proper function,
never test the “safety” while your firearm is loaded or
pointed in an unsafe direction.
3 WHENEVER YOU HANDLE ANY FIREARM, OR HAND IT
TO SOMEONE, ALWAYS OPEN THE ACTION
IMMEDIATELY AND VISUALLY CHECK THE FIREARM’S
CHAMBER TO MAKE CERTAIN THAT THE FIREARM IS
COMPLETELY UNLOADED.
Make certain the firearm does not inadvertently
contain any ammunition. Remember, merely
removing the magazine does not mean the chamber
is unloaded. Always keep the chamber empty and
the “safety” in the on safe position unless shooting
is imminent.
4 ALWAYS WEAR EAR AND EYE PROTECTION
WHEN SHOOTING.
Unprotected, repeated exposure to gunfire can cause
hearing damage. Wear hearing protection (shooting
ear plugs or muffs) to guard against such damage.
Wear shooting glasses to protect your eyes from flying
particles. Allow proper distance (eye relief) between a
scope and your eye when firing a scoped pistol, rifle or
shotgun. Do not use unorthodox shooting methods
that could cause the rearward travel of the slide or bolt
of a firearm to contact your eyes, face or hands.
Always keep a safe distance between the muzzle of
your firearm and any persons nearby, as muzzle blast,
debris and ejecting shells could inflict serious injury.
Always wear eye protection when disassembling and
cleaning any firearm to prevent the possibility of
springs, spring-tensioned parts, solvents or other
agents from contacting your eyes.
5 KEEP ALL FIREARMS UNLOADED DURING
TRANSPORT, EVEN WHEN STORED IN A HOLSTER,
GUN CASE, SCABBARD OR OTHER CONTAINER.
6 DROPPING OR JARRING A LOADED FIREARM CAN
CAUSE ACCIDENTAL DISCHARGE.
2
This can occur even with the “safety” in the on safe
position. Be extremely careful while hunting or during
any shooting activity to avoid dropping any firearm.
7 HUNTING FROM ELEVATED SURFACES SUCH AS
TREESTANDS IS DANGEROUS.
Doing so may increase the risk of mishandling a
firearm. The following rules should always be observed
by you and those you hunt with. Always make certain
that the stand being used is safe and stable. Always
make certain that your firearm is unloaded when it is
being taken up and down from the stand. Always
make certain that your firearm is not dropped from the
stand, or dropped while it is being taken up or down
from the stand. Remember, a loaded firearm may
discharge when dropped, even with the “safety” in the
on safe position.
8 STORE YOUR FIREARM AND AMMUNITION
SEPARATELY, WELL BEYOND THE REACH
OF CHILDREN.
Take prudent safeguards to ensure your firearm does
not become available to untrained, inexperienced or
unwelcome hands. Store all firearms in secure, locked
cases or a gun safe. Keep your firearm unloaded when
not in use.
9 BEWARE OF BARREL OBSTRUCTIONS.
Mud, snow and an infinite variety of other objects may
inadvertently lodge in a barrel bore. It only takes a
small obstruction to cause dangerously increased
pressures that can damage your firearm and cause
serious injury to yourself and others.
BEFORE CHECKING FOR A BARREL OBSTRUCTION,
BE CERTAIN YOUR FIREARM IS COMPLETELY
UNLOADED, THERE IS NOT A LIVE SHELL IN
THE CHAMBER AND THE “SAFETY” IS IN THE
ON SAFE POSITION.
After assuring yourself that the firearm is completely
unloaded, open the breech or action and look through
the barrel to be sure it is clear of obstructions. If an
obstruction is seen, no matter how small it may be,
clean the bore with a cleaning rod and patch as
described on pages 28-31 of this owner’s manual.
10 BE ALERT TO THE SIGNS OF AMMUNITION
MALFUNCTION. IF YOU DETECT AN OFF SOUND OR
LIGHT RECOIL WHEN A CARTRIDGE OR SHELL IS
FIRED, DO NOT LOAD ANOTHER CARTRIDGE OR
SHELL INTO THE CHAMBER.
If your firearm fails to fire, keep the muzzle pointed in
a safe direction for a minimum of 30 seconds. Rotate
the ejection area of the firearm away from you,
carefully open the action and remove the cartridge or
shell from the chamber. If the primer is indented, the
defective cartridge should be disposed of in a way that
cannot cause harm. If the primer is not indented, your
firearm should be examined by a qualified gunsmith
and the cause of the malfunction corrected before
further use. Glance down the barrel to make sure that
3
no obstructions remain in the barrel. Completely clear
the barrel before loading and firing again. Failure to
follow these instructions can cause extensive damage
to your firearm and possible serious injury to yourself
and others.
11 NEVER INSERT A SHELL OF THE INCORRECT
GAUGE INTO ANY FIREARM.
The gauge of your firearm is marked on the barrel.
Store all shells of different gauges in completely
separate and well-marked containers. Never store shells
of mixed gauges in a common container or in your
pockets. See pages 17-18 for more information on the
correct ammunition for your firearm.
12 EXAMINE EVERY SHELL YOU PUT IN YOUR FIREARM.
We assume no responsibility for the use of unsafe or
improper firearm and ammunition combinations or
damage or injury caused by damaged ammunition.
It is your responsibility to read and heed all warnings in
this owner’s manual and on ammunition boxes.
See pages 17-18 for more information on the correct
ammunition for your firearm.
13 USE ONLY SAAMI APPROVED AMMUNITION.
The barrel and action of this firearm have been made
with substantial safety margins beyond the pressures
developed by established American commercial loads.
Nevertheless, we can assume no liability for incidents
which occur through the use of shells of nonstandard
dimensions or which develop pressures in excess of
commercially available ammunition which has been
loaded in accordance with standards established by the
Sporting Arms and Ammunition Manufacturers’
Institute (SAAMI).
14 MAKE SURE OF ADEQUATE VENTILATION IN THE AREA
THAT YOU DISCHARGE A FIREARM. LEAD EXPOSURE
CAN OCCUR FROM DISCHARGING FIREARMS IN
POORLY VENTILATED AREAS, CLEANING FIREARMS
OR HANDLING AMMUNITION.
Lead is a substance that has been known to cause birth
defects, reproductive harm and other serious injury.
Wash hands thoroughly after exposure to ammunition
or after cleaning a firearm.
15 DO NOT SNAP THE FIRING PIN ON AN EMPTY
CHAMBER; THE CHAMBER MAY NOT BE EMPTY!
Treat every firearm with the respect due a loaded
firearm, even though you are certain the firearm
is unloaded.
16 KEEP YOUR FINGERS AWAY FROM THE TRIGGER
WHILE LOADING AND UNLOADING UNTIL
SHOOTING IS IMMINENT.
17 BE SURE OF YOUR TARGET AND BACKSTOP,
PARTICULARLY DURING LOW LIGHT PERIODS.
Know the range of your ammunition. Never shoot at
water or hard objects.
4
18 ALWAYS UNLOAD YOUR FIREARM’S CHAMBER
BEFORE CROSSING A FENCE, CLIMBING A
TREE, JUMPING A DITCH OR NEGOTIATING
OTHER OBSTACLES.
Never place your firearm on or against a fence, tree,
car or other similar object.
19 BE DEFENSIVE AND ON GUARD AGAINST UNSAFE
GUN HANDLING AROUND YOU AND OTHERS.
Don’t be timid when it comes to firearm safety. If you
observe other shooters violating any of these safety
precautions, politely suggest safer handling practices.
20 BE CERTAIN YOUR FIREARM IS UNLOADED
BEFORE CLEANING.
Because so many firearm accidents occur when a
firearm is being cleaned, special and extreme care
should be taken to be sure your firearm is unloaded
before disassembly, cleaning and reassembly.
Keep ammunition away from the cleaning location.
Never test the mechanical function of any firearm
with live ammunition.
21 TEACH AND SUPERVISE FIREARMS SAFETY TO ALL
MEMBERS OF YOUR FAMILY, ESPECIALLY TO
CHILDREN AND NON-SHOOTERS.
Closely supervise newcomers to the shooting sports.
Encourage enrollment in hunting and shooting
safety courses.
22 NEVER DRINK ALCOHOLIC BEVERAGES OR
TAKE ANY TYPE OF DRUGS BEFORE OR
DURING SHOOTING.
Your vision, motor skills and judgment could be
dangerously impaired, making your gun handling
unsafe to you and to others.
23 READ AND HEED ALL WARNINGS IN THIS
OWNER’S MANUAL, ON AMMUNITION BOXES
AND WITH ALL ACCESSORIES THAT YOU INSTALL
ON YOUR FIREARM.
It is your responsibility to secure the most up-to-date
information on the safe handling procedures of your
Winchester firearm. We assume no liability for
incidents which occur when unsafe or improper
firearm accessories or ammunition combinations
are used.
24 PRACTICE PERIODIC MAINTENANCE, AVOID
UNAUTHORIZED SERVICING.
Your firearm is a mechanical device which will not
last forever, and as such, is subject to wear and
requires periodic inspection, adjustment and service.
Winchester firearms should be serviced by a
Winchester Repeating Arms Authorized Repair
Center or by our Service Facility in Arnold, Missouri.
We assume no responsibility for injuries suffered or
caused by unauthorized servicing, alterations or
modifications of Winchester firearms.

Balance. Pointability. Reliability. Handling. These are
qualities you expect in an over and under, and they’re
what you’ll get with your Model 101. It’s superbly
designed, combining the traditions of American hunting
guns and European competition guns. These shotguns
provide a lively feel, with dimensions designed to allow
you to quickly move to your target. The low-profile
receiver with dual, between-the-barrel lockup is the
foundation, and combined with ideal stock dimensions,
put you on target consistently.
The Model 101 is an over and under shotgun made to fire
two successive shots by pulling the trigger twice, once for
each shot. Each time the action is opened after firing the
hammers are cocked automatically and empty shells (one
or two) are ejected clear of the chamber(s) automatically.

Unfired shells are elevated in the chambers. The action is
opened with a lever mounted on the top of the receiver
just forward of the “safety”/selector. The shotgun breaks
down into three pieces for cleaning or storage (Figure 2).
Prior to using live ammunition, familiarize yourself
thoroughly with all the operating instructions in this
owner’s manual. Get accustomed to the feel of your new
firearm. Know the forces required to operate the action.
Understand how to select the firing order of the barrels.
Learn how to pull the trigger correctly, and above all,
know the location and operation of the “safety”/selector.
Procedures for disassembly and operation of various
components are outlined in the following sections. Please
read and study them thoroughly.

The top-tang “safety”/selector offers
excellent convenience with gloved fingers.
Target models feature a
trigger that adjusts for
length of pull (pages 23-24).
The dual locking pins are made to stay tight under years
of heavy use. The locking pins are larger and sturdier than
the competition’s shotguns and optimize the strength of the
action while allowing an overall lower profile of the receiver
than found on some other over and under shotguns.
The compact, low-profile receiver features
an ideal combination of action strength
and balance. The receiver is quick and
lively, not too small and not too bulky.
When empty shells are ejected, they leave
the chambers at virtually the same time,
flying side-by-side through the air. This is
a sign of a well-timed mechanism.
Deluxe recoil pad provides
maximum comfort.

Barrels are back-bored for improved pattern performance. Backboring means that the barrels are made with a slightly larger inner
bore diameter than traditional dimensions. This results in less
resistance to the shot column as it moves down the bore and less
deformation of pellets as they move through the forcing cone. There
is also a slight decrease in perceived recoil.
The durable rib design is available in both
field and sporting widths.
The barrels and forearm remove
for easy cleaning and storage.
All Model 101 and Select shotguns are fitted with the
proven Invector-Plus
™
choke tube system. These longer
tubes have special tapers for optimum patterning and are
specially designed for back-bored barrels. This allows you
to easily change choke constrictions to meet the demands
of the game or target.

nomenclature
In conventional firearm terminology the position and
movement of firearm parts are described as they occur with
the firearm horizontal and in normal firing position: i.e.,
the muzzles are forward or in front; the buttstock is
rearward or to the rear; the trigger is downward or
underneath; the rib is upward or on top. For general parts
nomenclature, refer to Figure 1, page 6.
The shotgun is also shown disassembled to the extent
necessary in order to follow instructions contained in
this owner’s manual in Figure 2 on page 7. Details of
the action are shown in Figure 3 and Figure 4 (page 7).
Figure 5 (pages 8-9) covers the general features and
benefits of the Model 101 design.
Throughout this owner’s manual the “action” refers
to the mechanism of this shotgun that secures the shells
in the chambers.
Serial number
The serial number is located on the top tang of the
receiver under the top lever. Duplicate numbers are also
located on the bottom of the barrels (when removed) on
the flat surface crossing the barrels below the trunnion
surface and inside the forearm. Record the serial number at
the front of this owner's manual for future reference.
NOTICE! DO NOT INTERCHANGE THE RECEIVER, BARRELS
OR FOREARM WITH OTHER SHOTGUNS EVEN THOUGH
THE PARTS MAY APPEAR SIMILAR.

NOTICE! PLEASE TAKE NOTE OF THE FOLLOWING
INFORMATION BEFORE CLEANING YOUR FIREARM.
clea ning par tS With Spec ial fini SheS
Be especially careful when cleaning firearms with
camouflage, Dura-Touch
®
Armor Coating and other
special finishes. Always prevent these surfaces from
coming in contact with cleaning solvents, barrel scrubbers
and other strong chemicals. It is preferable to clean these
surfaces with a light gun oil containing no solvents or with
a damp cloth and mild dish soap (be sure to keep water out
of the action). When cleaning your firearm’s bore and
action, protect the external finishes from any contact with
chemicals used. Also, avoid any contact between external
finishes and other strong chemicals like those found in
DEET-containing insect repellents, sunscreens, etc.
Damage to camouflage, Dura-Touch and other finishes
caused by chemicals is irreversible and not repairable.
WEAR EYE PROTECTION WHEN ASSEMBLING AND
DISASSEMBLING YOUR SHOTGUN TO PREVENT SPRINGS,
SPRING-LOADED PARTS, SOLVENTS OR OTHER AGENTS
FROM CONTACTING YOUR EYES, RESULTING IN INJURY.
Some metal parts of your new firearm have been coated at
the factory with a rust preventative compound. Before
using your shotgun, clean the anti-rust compound from the
inside of the barrels, receiver area, locking pin mechanism,
10
extractors/ejectors, hinge surfaces and the chamber areas.
A high quality, lightweight gun oil should be used to
remove this compound and to give your new firearm its
first lubrication. Clean the barrels using a cleaning rod
and patch as explained under “Cleaning and Maintenance
Suggestions” on pages 28-31.
If your firearm is to be stored for an extended period of
time, it is permissible to leave the rust preventative
compound in place and keep your firearm in its box for
maximum protection during long-term storage.
Before beginning assembly of your firearm you should first
wipe the mechanism clean and apply a few drops of quality
oil on the surfaces shown (Figure 6 and Figure 7). Grease
is recommended to lubricate the hinge surfaces on both
sides of the receiver to prevent galling. Avoid applying too
much lubricant, as only a light film is necessary. Excessive
lubricant should be wiped off.

UNLESS SHOOTING IS IMMINENT. VISUALLY CHECK
YOUR “SAFETY” TO BE CERTAIN IT IS IN THE ON SAFE

FOLLOW THESE WARNINGS COULD RESULT IN SERIOUS
INJURY OR DEATH.
FIGURE 6

Your shotgun is designed with a top-tang mounted
“safety”/selector. It is located just rearward of the top lever
on the top tang, and is convenient to operate. It is
operated with the thumb of your rearward hand when
holding the firearm in shooting position.
To place the firearm on safe, pull the “safety”/selector fully
to the rear with your thumb. When the “safety”/selector
is fully rearward an “S” is exposed at the front of the
“safety”/selector. This shows you visually that the “safety”
is in the on safe position (Figure 8, page 12). With the
“safety” in the on safe position the trigger is disconnected
and the shotgun cannot be fired.
To place the firearm off safe, push the “safety”/selector
fully forward with your thumb (Figure 9, page 12). When

the “safety”/selector is fully forward the “safety”/selector
covers the “S.” In the off safe position — if your shotgun
is loaded with shell(s) in the chamber(s) — the
chambered shell(s) can be fired by simply pulling
the trigger.
At all times in the field keep the “safety”/selector in the
on safe position and the barrels pointed in a safe direction.
It is a good idea never to load your shotgun until you are
in the field, at the location you intend to begin hunting or
you are at your station on a range and it is your turn to
shoot. For extra safety on a range, and as a courtesy to
others, fully unload the chambers and keep the action
open at all times other than when it is your turn to shoot.

barrel Selector
The “safety”/selector on the top tang of your shotgun also
serves as the barrel selector. The barrel selector allows you
to choose which barrel will fire with the first pull of the
trigger. The other barrel will then fire with the second
pull of the trigger. The “safety”/selector must be in the on
safe rearward position to operate the barrel selector.
The “safety”/selector can be moved to the right or left
covering and uncovering the letters “U” and “O.” On the
left side of the “safety”/selector the letter “U” stands for
“under.” On the right side the letter “O” stands for “over.”
Often different chokes are installed in each barrel which
have different constrictions. This may make one barrels
choke preferable for a certain shot. Also there is slightly
less muzzle jump when the lower barrel is fired first,
making it easier to pick up your target for a follow-up
shot. The barrel selector allows you to choose the best
choke and barrel firing order combination for rapidly
changing hunting conditions or to adapt to the layout
of a sporting clays station.
Always make sure that the selector switch is completely
to one side or the other. If the switch is inadvertently
positioned directly between “O” and “U” the “safety”/
selector switch may be more difficult to move to the
off safe position.
top lever
The top lever operates the locking pins, which are fitted
to the barrel lugs. Moving the top lever to the right
unlocks the action and allows the shotgun to be loaded
and unloaded.
It is not necessary that the top lever return to a
completely centered position, nor should it hang over the
right side or edge of the receiver tang. Upon closing the
action, let the top lever snap into position to allow the
top lever spring to return the top lever mechanism to the
locked position. Do not retard its action with your thumb.
FIGURE 12
When closed, the top
lever may still be
slightly to the right.
Many shooters lightly push the top lever to the left after
the closing the breech. This operation is a quick method
of assuring yourself that foreign matter has not interfered
with the complete closure of the breech.
Always keep the polished breech surfaces clean and lightly
oiled. The breech is so carefully hand-fitted that
accumulated debris, sand, etc. may prevent complete
closing. If this should occur the action will not close.
Open the action and unload it. Carefully examine the
action surfaces and remove any foreign matter.
Additionally, provision is made for the gradual wear of
locking surfaces to keep the action tight. It is common,
because of the tight tolerances and craftsmanship of your
shotgun, for the top lever to be just slightly right of center,
even when the action is fully closed (Figure 12).
13

This is the result of tight tolerances which assure your
shotgun of excellent receiver-to-barrel fit for many years
to come and is the sign of a finely crafted firearm.

Trunnion Surface
Attach the barrels by aligning the
trunnion surfaces on the barrels with
the trunnions on the receiver.
Your shotgun will come from the factory partially
disassembled. Prior to assembly clean and lightly oil
component parts as explained under “Initial Cleaning
and Oiling” (Page 10).
It is important to carefully follow the assembly
instructions below to assure the proper assembly of
your shotgun.
1. Inspect the chambers and action areas, and clean dirt
and/or excess oil from them as explained on page 10.
2. Remove the forearm from the barrels by holding the
barrels with one hand and pull out on the forearm
release latch with the other (Figure 13).
3. Attach the barrels (without the forearm attached to
them) to the action by first holding the barrels with

Hold at an angle.
the muzzles at a downward angle with respect to the
receiver. Then push the top lever to the right.
Carefully engage the surfaces of the trunnions (located
inside the forward portion of the receiver) with the
curved trunnion surfaces on the monoblock, located
on each side of the bottom barrel (Figure 14, page 14).
4. With the monoblock properly seated on the trunnions,
lift up on the barrels and close the action. Make sure
the monoblock and trunnions remain in proper
alignment. When performing assembly procedures it
also helps to keep the top lever pushed fully to the
right with your thumb until the action is closed. When
the action is fully closed release the top lever and the
action will be locked in the closed position.
If the action seems difficult to close, the monoblock
and trunnions may not be properly engaged. Release
the upward pressure and carefully separate the barrels
from the action again. If forced, you may mar and
damage the fine fit of your shotgun’s action.
5. Once the barrels are installed and the action closed,
replace the forearm on the shotgun by sliding the
radiused rear surface of the forearm extension at an
angle into the radiused front edge of the receiver.
Match the shape of the rear of the forearm to the
shape of the front of the receiver (Figure 15). Lift the
front of the forearm until it engages with the barrels
with an audible click. If it does not click, gently slap
the forearm just above the latch with the palm of your
hand. If the forearm release latch protrudes carefully
push it into place, but do not force the latch. Your
shotgun is now fully assembled.

FIGURE 16
Lift up and out to separate the
barrels from the receiver.
Disassembling your shotgun into its two assembly
components is an ideal way to ready your shotgun for
storage and cleaning. Many luggage-style cases require
doing this. It is also a way to add an extra measure of
safety when storing your firearm.
1. Make sure your shotgun is unloaded and make sure
that the “safety”/selector is in the on safe position.
2. Remove the forearm by pulling outward on the
forearm release latch and pulling the forearm away
from the barrels. Pull the front-most end of the
forearm away and slightly forward, completely
detaching it from the barrel set and the front of
the receiver.
USE CARE WHEN REMOVING THE FOREARM. DO NOT
PULL DOWN TOO HARD ON THE FOREARM OR PULL IT
AWAY FROM THE BARRELS TOO FAR. DOING SO MAY
CRACK THE FOREARM.
3. Grasp the barrels ahead of the receiver and push the
top lever to the right with your thumb. Rotate the
barrels downward until they separate from the
receiver. Be sure to support the barrels and buttstock
carefully. When the barrels are fully down, carefully
lift the hinge portion of the barrels (at the receiver)
upward out of the receiver, separating the barrels from
the receiver (Figure 16).
4. If you are cleaning your shotgun, this is the ideal level
of disassembly.
5. When cleaning is completed, reattach the forearm to
the barrels for storage. This is done very easily when
the barrels are detached. Simply align the forearm
extension along the bottom of the barrel so that the
forearm extension aligns with the rails on each side
of the chambers. Make sure the ends of the rails line
up with the rear top edge of the forearm (Figure 17,
page 17). The forearm can be angled slightly or
positioned parallel with the barrels. Press with even
pressure using both hands, front to back, along the
forearm. As the forearm snaps into position, the
release latch may briefly protrude from the bottom of
the forearm. It will snap down flush with the forearm
when it is secured in position correctly.

The most certain way to bulge or rupture a shotgun barrel
is to load a smaller gauge shell into a larger gauge chamber.
The smaller gauge shell will not fall completely through
the barrel; its rim is caught by the front of a larger gauge
chamber or at the larger gauge’s choke. Your shotgun will
misfire (with the chamber appearing to be empty). It is
then possible to load the correct gauge shell behind the
smaller gauge shell. If the shotgun is then fired, the result
will be a so-called “12-16, 12-20, 20-28 or 28-.410 burst”
which can cause extensive damage to your shotgun and
possible serious injury to you and others.
We can assume no responsibility for incidents which occur
through the use of shells of nonstandard dimension or
those developing pressures in excess of SAAMI (Sporting
17
Arms and Ammunition Manufacturers’ Institute)
established standards.
There are several different versions of the Model 101. The
gauge and chamber length are inscribed on the side of the
barrel, forward of the receiver. They are inscribed as
follows:
ammunition is always an excellent choice for
your new Winchester firearm, delivering the unmatched

WHEN LOADING YOUR SHOTGUN ALWAYS KEEP THE
MUZZLES POINTED IN A SAFE DIRECTION, ALWAYS
PLACE THE “SAFETY” IN THE ON SAFE POSITION AND
KEEP YOUR FINGERS AWAY FROM THE TRIGGER.
FAILURE TO FOLLOW THESE WARNINGS COULD RESULT

FIRING IS NO LONGER IMMINENT, MAKE SURE THE
“SAFETY” IS IN THE ON SAFE POSITION AND UNLOAD
THE CHAMBERS. FAILURE TO FOLLOW THESE WARNINGS
COULD RESULT IN SERIOUS INJURY OR DEATH.
1. Make sure the “safety”/selector is in the on
safe position.
2. Open the action by pushing the top lever to the right
with the thumb of your right hand. Left-handed
shooters usually push the lever by reaching across with
their left thumb.
3. Visually check to make sure there are no obstructions
in the chambers or bores of the barrels.
4. Insert a shell in each chamber or in the chamber you
plan to fire. Make sure the shell(s) are fully forward in
the chamber(s), with the rim(s) in direct contact with
the edge of the extractors/ejectors (Figure 18, page 19).
5. Close the action by lifting up on the forearm, hinging
the barrels upward into position, until the action is
fully closed. When closed, the top lever will snap back
into the center position. There should be no space
between the face of the barrels and the face of the
receiver when the action is fully closed (Figure 19,
page 19).

3. When shooting is imminent, move the “safety”/
selector to the off safe position. Take aim and, when
ready, squeeze the trigger to fire. After firing one
barrel, it is not necessary to move the “safety”/selector
to fire the second barrel. Simply release the trigger to
its original forward position and pull it a second time.
Be certain you fully release the trigger between shots.
If the trigger is not permitted to return to its fully
forward position, the firing mechanism will not
reengage and the subsequent trigger pull will fail to
fire the remaining shell. Failure to release the trigger
ordinarily occurs with overly rapid firing or heavily
gloved fingers.
4. After you have completed firing you should either
reload the chamber(s) with unfired shells (if hunting/
shooting is going to continue) or fully unload your
shotgun (if shooting is completed). Regardless, always
first place the “safety”/selector in the on safe position.
Be sure to open the action completely between shots
to reset the firing mechanism.
AFTER FIRING, OR WHEN SHOOTING IS NO LONGER
IMMINENT, IMMEDIATELY PLACE THE “SAFETY” IN THE
ON SAFE POSITION. FAILURE TO FOLLOW THIS WARNING
COULD RESULT IN SERIOUS INJURY OR DEATH.
For training purposes or in some target situations your
firearm can be fired “single shot” by loading one shell
at a time in only one of the chambers. For training new
shooters, the bottom barrel is often used because of its
slightly lower perceived recoil. Make sure the “safety”/
selector is set for the barrel you wish to fire.

The ejector/extractor mechanism mechanically adapts to
whether there is a fired shell or a loaded shell in a
chamber. With a loaded shell the mechanism acts as an
extractor, elevating the shells in the chamber. With a
fired shell it acts as an ejector, forcefully ejecting the
empty shell clear of the chamber and onto the ground.
1. Using your thumb, move the top lever fully to the
right to open the action. The action must be opened
completely to reset the firing mechanism. Due to tight
manufacturing tolerances, it may be necessary to pull
20
downward slightly on the forearm to completely open
the breech. For proper ejection, keep the receiver
level and allow the barrels to completely drop. This
keeps empty hulls in full contact with the ejectors.
2. It is important to point the breech, by canting the
shotgun to the right (or to the left for left-handed
shooters), so empty hulls eject clear of your body and
face. Fired shells will be thrown completely out of the
shotgun upon opening the action. Remember to pick
up all of your empties after you have finished shooting
so as to not to cause litter.
Unfired shells will be elevated in the chambers by the
extractors. They can be unloaded from your shotgun
by pulling the unfired shell(s) out of the chambers
with your fingers.
If only one barrel has been fired, only the fired
hull will be ejected upon opening of the action.
If shooting is imminent, a loaded shell can be
inserted in its place.

choke system. Standard Invector,
WinChoke and Invector-Plus tubes are not
interchangeable. Confirm the choke system of your
shotgun by looking on the right side of the barrel where
the specifications are inscribed, where the choke markings
are normally located.
The constriction of each choke tube is indicated twice on
the choke tube: on the side of the tube, and indicated
with a “notch” code on the top rim of the tube. The
included universal choke tube wrench is used to remove
and install choke tubes.
Some target shotguns include premium extended choke
tubes. The constriction of premium choke tubes is
indicated twice on the choke tube: on the side of the
tube, and indicated with an abbreviation in the colored
band. The constriction of flush fit choke tubes is
indicated twice on the choke tube: on the side of the
tube, and indicated with a “notch” code on the top rim
of the tube. The included choke tube T-Wrench is used
to remove and install extended choke tubes.
Choke tubes are compatible with factory ammunition
that has been loaded in compliance with SAAMI
specifications, including magnum lead and steel shot
loads, sabots and shotgun slug loads.
Replacement and additional tubes and wrenches are
available from your Winchester Repeating Arms dealer, or
by contacting the Winchester Repeating Arms Customer
Service Department. See page 32 for contact information.
chok e tu be Selec tion
To help you choose the correct choke tube for each
hunting and shooting situation, all Invector-Plus choke
tubes are inscribed on the side with the patterns
they produce with both lead and steel shot. Each
Invector-Plus tube also has notches in the top rim of the
tube (Figure 20, page 23). These notches are a code to
allow you to determine the choke designation while the
tube is installed. Rim notches refer specifically to lead
shot. Use the charts on this page to cross-reference from
lead to steel, and determine the appropriate tubes for your
ammunition and hunting/shooting situation.
Several choke tubes are supplied with your shotgun.
The choke tubes listed are also available as accessories.
Remember, WinChoke, Standard Invector and InvectorPlus tubes are not interchangeable. Before removing or
installing tubes, or reading the rim notch code, make sure
your shotgun is completely unloaded and the “safety” is in
the on safe position.

Some shotguns are fitted with a special trigger shoe system
that allows you to make small adjustments to the length of
pull. This feature is usually found on target models where
shooters benefit from highly customized settings. It is easy
to change the length of pull using the 1.5 mm Allen (hex
head) wrench included with your firearm.
1. Place your firearm upside down on a secure, padded
surface to prevent marring the finish.
2. Using the Allen wrench provided (any good 1.5mm
Allen wrench will work) loosen the trigger shoe from
the trigger plate by inserting the wrench from the
bottom into the set screw head (Figure 21). Turn in a
counterclockwise direction to loosen.
3. When the screw is sufficiently loose you will be able
to move the trigger shoe along the trigger plate with
your fingers. There are indexing dots on the trigger
shoe and on the plate. Line up the dots to make
length of pull longer or shorter as desired.
4. Tighten the set screw snugly (do not overtighten)
with the Allen wrench to secure the trigger shoe to
the plate (turn in a clockwise direction to tighten).
Make sure you have aligned the indexing dots in
order to prevent marring the bottom of the trigger
plate with the set screw.
5. With your firearm unloaded, and pointed in a safe
direction, shoulder your firearm several times to feel
how the adjustment changes fit you. Increase or
decrease the length of pull following the instructions
above if necessary. Do not adjust more than allowed
by the “dot” index marks on the plate and trigger
shoe. When you find your preferred adjustment, tighten
the set screw. Always make sure the trigger shoe is
secure before firing. Checking the tightness of the set
screw should be part of your regular maintenance.

Some shotguns are fitted with an adjustable stock that
allows you to make adjustments to the stock for cast and
drop. This feature is usually found on target models where
shooters benefit from highly customized settings.
Loosen the comb adjustment screws.
aDju Stin g ca St onan D ca St off
Adjusting cast on and cast off allows you to achieve a
perfect fit from the stock to your face. This is a most
crucial adjustment, as it determines how correctly and
consistently your eye will line up with the sight plane
along the barrel rib. A shotgun correctly adjusted for
cast on and cast off will have you looking directly down
the center of the rib with the front and middle beads
in alignment.
1. Using a 3mm Allen wrench, loosen the two comb
retaining screws on the right side of the removable
cheekpiece and remove the cheekpiece by lifting
upward (Figure 22). This exposes the cast on and cast
off adjustment mechanism. (The cheekpiece comes
set from the factory with cast in the center position.)

2. Loosen both the comb adjustment stud screws
located in the top of the stock adjustment studs

to loosen them adequately.
3. Slide each stud equally in the desired direction.
Each mark indicates

4. Move the studs to the right for cast off (Figure 24).
5. Move the studs to the left for cast on (Figure 25).
6. Right-handed shooters may desire some cast off, with
left-handed shooters preferring some cast on. The
terminology is the same for right- or left-handed
shooters. The net effect is to move the cheekpiece to
allow the face to move farther over the stock for
better eye-to-rib alignment.
7. When properly set, the front and rear sight beads
should line up perfectly each time you shoulder
your shotgun.
8. Tighten the stock adjustment screws. Be careful not to
over tighten.
9. Replace the cheekpiece onto the studs. If drop at
comb has already been set to your desired height,
tighten the two comb retaining screws securely.
If drop has not been set, leave the retaining screws
loose and proceed to “Adjusting Drop at Comb.”
aDju Stin g Dr opat comb
Adjusting the drop at the comb allows you to align your
eye perfectly with the plane of the rib.
The drop measurement is determined by measuring the
distance between the plane formed by the top of the rib
and the top of the cheekpiece itself. The higher the
cheekpiece, the lower the drop. To set drop, perform
the following:
1. Loosen the two stock adjustment set screws on the
right side of the cheekpiece (if they were not left loose
after setting the cast) using a 3mm hex (Allen)
wrench. The cheekpiece will now move freely, up and
down on the stock adjustment studs.
2. Position the cheekpiece on the studs at the desired
drop up or down on the stock. Make sure the
26
adjustment on each stud is equal up and down. When
you have determined a possible setting, lightly tighten
the stock adjustment screws and then shoulder the
firearm to test the setting. Drop adjustments are a
matter of trial and error. Adjust a little at a time until
you obtain the desired sight picture on the rib.
3. Once your desired drop at comb is obtained, secure
the cheekpiece in place by tightening the two stock
adjustment set screws on the right side of the
cheekpiece. Drop is now set on your shotgun.
barrel porting (Special moDelS)
Some target models feature ported barrels that reduce
recoil and muzzle jump. Reducing recoil not only
increases comfort when shooting, but increases accuracy
because it is easier to pick-up the second clay target faster
due to decreased recovery time following the first shot.
Carbon can build up in the ports after shooting. To clean
them use a good quality powder solvent and pipe cleaners
to scrub away debris.
BARREL PORTING INCREASES NOISE AND MUZZLE

Keeping the oil-finished wood surfaces on your firearm
looking their best requires only a small amount of
maintenance. When the surfaces become spotted or dull,
the affected area(s) can be treated using rubbing alcohol
on a soft, lint free cloth and allowed to dry. A small
amount of a linseed oil-based finish, such as Watco
Danish Oil Finish, Deft

Tung Oil Finish should then be applied to the surface of
the wood with a soft, lint free cloth according to the

a small amount of oil-based finish can be applied and
then distributed evenly using a toothbrush or other soft

As with any firearm, the only way to preserve its
pristine condition and collector appeal is to never
handle or fire it, which in turn would deprive you of
much of the enjoyment that comes with owning a fine

While special finishes such as engraving and gold plating
greatly enhance the aesthetic appeal of your shotgun,
please be aware that they are no more durable, and in
some cases may even be slightly less durable than more
common firearm finishes.

As you use your Winchester shotgun, you can expect
special finishes to wear in much the same manner as any
other firearm finish. These marks are the honest product

clea ning pro ceDu reS
Your Model 101 shotgun will function better and more
reliably over a longer period of time if it is properly
maintained and kept clean. You should clean your shotgun
after every day of shooting, and more often if it becomes
excessively dirty. The barrels should be cleaned and the
28
action wiped clean and oiled after every day of shooting.
Normal maintenance can be accomplished with the
barrels still attached to the receiver (oiling/greasing and
wiping down). More careful cleaning requires removal
of only the barrels and forearm from the receiver (cleaning
the barrel).
If a malfunction occurs, perform a thorough cleaning to
see if it solves the problem before seeking the services of a
Winchester Repeating Arms Authorized Repair Center,
or by contacting the Winchester Repeating Arms Service
Facility in Arnold, Missouri, or a qualified gunsmith.
1. Place the “safety” in the on safe position. Open the
action and inspect the chambers to make certain they
do not contain any shells. Keep the muzzles pointed in
a safe direction.
2. Remove the forearm and barrels as explained under
“Disassembly” on pages 15-16.
3. Using a shotgun cleaning rod with tip and patch large
enough for a snug fit in the bore, insert the rod and a
lightly oiled patch in the breech end of the barrel and
run back and forth through the bore several times.
Remove and wipe the choke tube, threads and barrel
threads with a nylon brush and lightly oil. Reinstall
the choke tubes.
4. Inspect the bore from both ends for leading and plastic
residue that often remain in the bores from the shot
cups in modern shotshells. Leading and plastic residue
will appear as longitudinal streaks and are usually
more predominant near the muzzles and just forward
of the chambers. A normal amount of either is
common and not serious.
5. If leading or plastic residue seems excessive you can
remove it by brushing the bore with a brass brush.
Soak the brush or spray the bore with a powder
solvent first. Scrub until clean. To prevent bristles
from breaking off, push the brush fully through the
barrel each time before pulling it back through.
MOST SOLVENTS ARE HIGHLY FLAMMABLE. WEAR EYE
PROTECTION AND PRACTICE APPROPRIATE SAFETY
MEASURES WHEN WORKING WITH SOLVENTS TO AVOID
SERIOUS INJURY.
6. After all leading and plastic residues have been
removed, run a clean, dry patch through the bore.
Follow this with a final, lightly oiled patch.
7. Wipe all metal surfaces of the receiver, forearm and
barrels with a clean rag. Then lubricate your firearm at
the points noted on page 11. Regular, light lubrication
is extremely important to the durability and reliable
operation of your shotgun.
NOTICE! REMEMBER, THE BROAD, POLISHED FINELY
FITTED SURFACES OF THE RECEIVER AND FOREARM
MECHANISMS (THE BARREL LUGS, THE HINGE PIN AND
FOREARM BRACKET) MUST ALWAYS BE COATED WITH A
THIN FILM OF QUALITY LIGHTWEIGHT GUN OIL.
29
8. Reassemble the shotgun and wipe all exposed metal
surfaces with an oiled cloth making sure to wipe away
all finger marks where moisture could accumulate.
9. Inspect the barrels and chambers to be certain no
patches have inadvertently been left in them. Remove
any that remain.
10. The wood surfaces can also be wiped with a quality,
lightweight gun oil or they can be polished with any
quality furniture wax (but not both).
NOTICE! IT IS VERY IMPORTANT THAT THE CHAMBERS
OF YOUR SHOTGUN BE CLEANED THOROUGHLY AND
PROMPTLY AFTER SHOOTING PLASTIC SHOTSHELLS. DO
NOT LEAVE DISCHARGED (EMPTY) SHELLS IN THE
CHAMBERS FOR ANY LENGTH OF TIME. THE CHEMICAL
COMPOSITION OF MANY PLASTIC SHELLS CONTAINS
MOISTURE WHICH CAN “SWEAT” OUT OF THE SHELL
AND ONTO THE CHAMBERS’ SURFACES, AND POSSIBLY
CAUSE CORROSION AND RUST.
peri oDic oil ing
The metal parts of a firearm should receive a light film of
oil after the firearm has been exposed to weather or
handling. Lightly oil your firearm at the points described
under “Initial Cleaning and Oiling” found on pages 10-11.
Ordinary good judgment will, of course, indicate that the
metal of the firearm should receive a light film of oil any
time the firearm has been exposed to weather or handling.
This is very important and must be done with every
firearm. Remember, the polished, finely fitted surfaces of
the receiver and action mechanisms must always have a
thin film of lubrication. Make sure that the surfaces of the
locking pin system are especially clean and lightly
lubricated with a high-quality gun oil and the hinge
surfaces on both sides of the receiver are lightly greased to
prevent galling. If the firearm has been exposed to
excessive dust, dirt, mud or water, the principal working
parts should be wiped clean and lubricated with a light
film of quality, lightweight gun oil or grease.
NOTICE! DO NOT PLACE LARGE QUANTITIES OF OIL INTO
THE ACTION. EXCESS OIL WILL RUN BACK INTO THE
WOOD OF THE STOCK SOFTENING THE WOOD, WITH
CONSEQUENTIAL LOOSENING OF THE STOCK.
clea ning the inv ecto r-pl uS™ cho ke tube SYSt em
1. Never use a brass brush to clean your barrels unless
choke tubes are installed. Bristles could break off and
lodge in the threads, making installation and removal
of the choke tubes difficult.
2. Regularly remove the choke tubes in order to clean
and oil the threads inside the barrel, as well as on the
choke tube itself. This will protect the threads from
being damaged and also prevent a dirt build-up that
would cause the choke tube to become difficult to
remove. Clean the threads with solvent and a small,
soft brush like a toothbrush. Wipe completely clean
and leave a thin film of clean oil on the threads, both
on the tube and in the barrel. The threads of the
30
choke tube and the internal threads of the barrel
should be cleaned after each use and before the
installation of a tube.
3. Be careful when removing/installing a tube. Use the
specially designed wrench. Damage can result to both
choke tube and barrel when attempting to remove
sticky choke tubes.
4. Never fire your shotgun or run cleaning tools through
the barrel of any choke-tubed shotgun without having
the choke tubes installed.
