RANSOM "MASTER SERIES" REST
INSTRUCTIONS
Your Ransom Rest has been designed to give a maximum of
accuracy at minimum cost. It uses a new concept in its
recoil dampening system. The trigger release is also new in
concept and simplicity. Everything was designed to bring the
shooter a tool for testing that is portable, accurate and
simple.
BE POSITIVE THAT THE GUN IS UNLOADED BEFORE
INSERTING OR REMOVING IT FROM THE REST.
HAVE YOUR GUNSMITH CHECK ANY AUTOMATIC THAT DOUBLE FIRES OR
THE HAMMER WILL NOT STAY IN THE COCKED POSITION WHEN THE
SLIDE RETURNS TO BATTERY.
USE ONLY THE PROPER GRIP INSERT, REMOVE GRIPS FROM THE GUN
TO BE TESTED, EXCEPT WHERE NOTED OTHERWISE.
I Mounting the Ransom Rest without Windage Base
Your Ransom Rest is designed to be mounted on plywood, which
in turn is attached with C-clamps to a sturdy, permanently
mounted bench, at your pistol range. Select a good grade of
3/4" or 1" plywood, 14" wide and long enough to ex-tend
across the shooting bench you will be using. Three C-clamps
are sufficient, one in front and two in the rear. If
extensive hard ball or magnum testing is to be done, the
addition of another clamp on the front is recommended.
To the bottom side of the mount-board, glue and nail two
strips of wood, 2" x 1/2" x 14" at the front and rear. These
are to keep the center of your mount-board from contacting
the bench. Your mount-board should contact the bench only
on the front and rear 2" strips.

Remove the rocker assembly; with a 9/16" wrench back off the
friction tension bolt on the left side and remove rocker
assembly. Place base on your mount-board centered, twothirds of the distance toward the rear, centered from side
to side. Mark screw hole locations. Drill pilot holes for
#10 wood screws (supplied). Place the base over its
mounting position and install screws, tighten securely. Reassemble rocker to base.
IMPORTANT, be sure that the compression spring on the side
of the Ransom Rest is always kept at 1&1/2 inches.
While the above mounting method is preferred by us, the
Ransom Rest will work equally well mounted to a steel base
or atop a concrete base.
II Mounting of Pistol
1. Place your Ransom Rest on the bench at the position you
have selected, attach C-clamps to the bench and mount-board,
tighten moderately.
2. Remove the three star nuts and the outside clamp plate.
Slide the inside Grip Insert for the gun to be tested on to
the rocker assembly. Seat this insert all the way down on
the holding studs. Place outside Grip Insert on the Holding
studs and insert the gun to be tested into the inside Grip
Insert. Press the outside insert into position, moving the
gun slightly to make sure it is properly seated. Place
outside clamp plate on the holding studs, install washers
and star nuts.
3. Tighten star nuts, one-half turn at a time, alternating
"A" to "B", until both nuts are finger tight. Tighten nut
"C" just until it is snug. The most important part of this
operation is to make sure the gap between the inserts is the
same, front to rear and top to bottom. Some revolver
inserts will not have any gap in them when properly
tightened. Do NOT tighten star nuts with anything except
finger pressure!
III Operation
1. Two holes are provided in the trigger release finger to
get proper positioning of the finger on various guns. Adjust the release finger so that it comes in contact with the
center of the trigger, and the trigger release bar is about
level. On revolvers do this with the gun in the cocked
position. Check double action revolvers to make sure the
trigger has enough travel after the hammer has been released
for it to come forward its full travel.
2. Adjust your gun for elevation with the elevation screw.
When elevation is set, tighten the lock nut on the screw.
Ad-just windage and tighten all C-clamps securely.

3. The trigger release is easy to use in most any manner.
We recommend, to start with, you depress the bar with you
thumb while your index finger is supported by the tension
spring. Stand well to the rear of the rest, depress the bar
down and slightly outboard toward the index finger.
4. After each shot, depress the rocker assembly back to the
stop pad with the return lug on the right side of the
rocker. DO NOT USE THE GUN AS A LEVER!
NOTE: Certain handguns present special situations in using
the Ransom Rest. Please read the attachment (“Special
Situations”) to ascertain if your gun presents one of the
stated “situations”.
5. Load and fire five or more settling shots over your target. Now you are ready to shoot your group on the target.
6. We recommend that all test strings be of 10 or more
shots. When you change ammunition be sure that you fire
several fouling shots with the ammunition to be tested before you record your group.
NOTE:The small cap nut on the rear of the rocker assembly is
a safety stop for automatics. Remove this and the Allen stud
when testing large magnum revolvers. Make absolutely sure
that this is in place when you are testing any automatic.
MAINTENANCE: The only thing your Ransom Rest might need if
it has been kept inside when not in use, is a cleaning of
the friction discs. Remove the rocker assembly from the
rest base as mentioned in the directions. Clean both the
fiber and metal discs with acetone or lacquer thinner. Use
320-grade wet/dry sandpaper to remove any rust or
contamination of the steel disc. For the fiber disc use 180
grade. Remove any dark areas by using a sanding block.
When both discs are clean as well as the pivot pin and
bushing, place a small amount of lubriplate inside the pivot
bushing, coating the inside completely. Press the rocker
assembly onto the pivot pin and slide it into position. Any
excess grease will be pushed to the out side end of the
rocker assembly. Under no circumstances should any grease
or oil be allowed on the friction disc. Reassemble the
friction spring and thrust bearing compress spring to 1 1/2"
over all length.

SPECIAL SITUATIONS
Certain handguns present special situations when fired in
the Ransom Rest. Most often this occurs when you are firing
a polymer-frame pistol, such as a Glock, or when you are
shooting a large revolver or a single shot in a heavy
recoiling caliber. There are some things that help with
both situations. In neither case will you find the solution
in over-tightening the “star” nuts (A, B, & C) or tightening
the main coil spring adjustment to less than the required
length of 1 & 1/2 inches.
Polymer-frame autos sometimes compress slightly when gripped
in the inserts. Over-tightening compresses the grip to the
point where the pistol may not function properly. The
solution is to finger tighten the “star” nuts and shoot more
than the usual number of “settling” shots to work the pistol
down into the “rubber” of the inserts. It may take as many
as 20 or more rounds in order to properly settle the gun.
When the group produced on target is more nearly round than
vertically elongated, the adjustment is correct. Test
groups may now be fired.
In the case of hard-kick guns, such as a Contender in a big
caliber, follow the installation instructions to the letter.
The combination of hot ammo and the long barrel produces
severe recoil, often enough to turn the barrel to the full
vertical position. This applies to large revolvers also.
Resist the temptation to tighten the bolt that compresses
the large coil spring. Doing this will adversely affect the
braking mechanism inside the Rest and it will wear out
quickly. The solution lies in using more than a usual
number of settling shots. Be patient and shoot more rounds
until the group rounds out. Remember, a certain amount of
vertical stringing on target is perfectly normal and is
caused by variances in velocities inherent in even the best
of ammunition. This condition is particularly pronounced in
cold weather.
Use the Ransom Rest as it was designed and it will give you
many years of trouble-free, reliable results.
SAFETY WITH FIREARMS IS YOUR RESPONSIBILITY -- BE CAREFUL
We guarantee the exercise of reasonable care in the
manufacturing, but assume no further responsibility.

RANSOM REST WINDAGE BASE
INSTRUCTIONS
Disassemble the windage base and mount the bottom section on a mounting
board or on a suitable base where it is to be used. (Review the
recommendations in the Ransom Rest Instructions.) It should be secured
using all the mounting screw holes, with either metal or wood screws, as
the situation demands (10 x 1 1/4 round head wood screws are supplied for
your convenience).
Attach the Rest to the upper portion of the windage base with the 10/24 x 3/4
Phillips flat head machine screws supplied. Reassemble the windage base,
making sure that the thin
Tighten the front "football" knob and adjust the lateral location with the
adjustment knobs, tighten the rear two "football" knobs and make sure the
lateral adjustment knobs are snug.
CAUTION: If you are going to test .44 magnum or more powerful loads,
remove the left rear "football" knob (as viewed from the rear) and replace
it with a 5/16" X 18 nut. This is to provide extra clearance for the long
recoil movement.
