IMPORTANT: READ THIS SECTION FIRST
Before using the RCBS X-Sizer die, read this instruction manual carefully to fully learn how to safely operate the related reloading equipment.
Failure to properly operate certain reloading equipment can result in
severe personal injury and/or equipment damage. If you have read
these instructions, but do not clearly understand the described operation, call us at 1-800-533-5000 and a technician will assist you.
This instruction manual contains specific safety and operating information.
It should be considered a permanent part of your reloading equipment and
remain with the equipment at all times for easy reference.
SAFETY
Reloading is an enjoyable and rewarding hobby that can be conducted safely. But, as with any hobby, carelessness or negligence
can make reloading hazardous. This product has been designed
from the beginning with the user’s safety in mind. When reloading,
safety rules must be followed. By observing these rules, the chance
of a hazardous occurrence causing personal injury or property damage is minimized.
GENERAL
• Use all equipment as the manufacturer recommends. Study
the instructions carefully and become thoroughly familiar
with the operation of the product. If you do not have written
instructions, request a copy from the equipment manufacturer.
• Do not take short cuts. Attempting to bypass established
procedures is an invitation to an accident.
• Observe “good housekeeping” in the reloading area. Keep
tools and components neat, clean and orderly. Promptly and
completely clean up primer and powder spills.
• Reload only when you can give your undivided attention. Do
not reload when fatigued or ill, or under the influence of
medications or alcohol. Develop a reloading routine to avoid
mistakes which may prove hazardous. Do not rush - load at a
leisurely pace.
• Always wear adequate eye protection to protect your eyes
from flying particles. You assume unnecessary risk when
reloading without wearing safety glasses.
LOADING DATA
• Use only laboratory tested reloading data. We highly recommend the SPEER reloading manual and the RCBS.load
reloading software.
• OBSERVE ALLWARNINGS ABOUT THE USE OF MAXIMUM LISTED LOADS.

PRIMERS AND POWDER
• Store primers and powder beyond the reach of children and
away from heat, dampness, open flames and electrical equipment. Avoid areas where static electricity is evident.
• Do not use primers of unknown identity. Scrap unknown
primers in accordance with applicable regulations.
• Keep primers in the original factory container until ready to
use. Return unused primers to the same factory packaging for
safety and to preserve their identity. Primer packaging is
designed to provide safe storage.
• DO NOT store primers in bulk. The blast of just a few hundred primers is sufficient to cause serious injury to anyone
nearby.
• DO NOT force primers. Use care in handling primers.
• DO NOT have more than one can of powder on the bench at
one time. Powder cans should be stored away from the
bench to avoid picking up the wrong one.
• DO NOT use any powder unless its identity is positively
known. The only positive identification is the manufacturer’s label on the original canister. Discard all mixed
powders and those of uncertain identity.
• If you use a powder measure, replace the lids on both the
powder hopper and powder can after the powder hopper
has been filled.
• When using a powder measure, settle the powder in the
powder hopper before charging any cases. Throw and check
the weight of at least ten charges. This will assure you that
the correct powder charge is being thrown.
• When you finish a reloading session, pour any remaining
powder back into its original factory container. This will preserve the identity and shelf life of the powder.
• DO NOT smoke while reloading.
RECORD KEEPING
• Keep complete records of reloads. Apply a descriptive label
to each box showing the date produced, and the primer,
powder and bullet used. Labels for this purpose are packed
with SPEER bullets. Never attempt to guess at the
identity of your ammunition.
Because RCBS has no control over the type and condition of firearms used, components selected, assembly of those components
and the use of this product, we assume no responsibility, expressed
or implied, for the use of this product for reloading.

ABOUT THE X DIE
The X-Sizer die is a uniquely designed full length resizing die for
bottleneck rifle cases. This die not only full length resizes the
case, it also limits the growth of the case. This eliminates the
need for repeated trimming after an initial trim is done to standardize the case. This die is not intended to shorten the length of
the case, rather, as the case grows, the mandrel will reduce the
normal rate of growth. This is the result of the case mouth coming
in contact with the mandrel stop during resizing. Cases repeatedly
sized in the X-Sizer die will grow a few thousandths of an inch initially, and will then stabilize below the maximum case length.
Using the X-Sizer die eliminates the need to trim after each shot.
X-Sizer dies can be used for full-length resizing with or without
the X feature. Partial neck sizing can be done but only without
the X feature.
CLEANING THE X DIE
You MUST clean new dies before use.
These dies contain a
small vent hole through which trapped air escapes during resizing. Sometimes the vent hole will plug up with factory polishing
material. This material will scratch and dent cases unless it is
removed. To clean, unscrew the mandrel from the die. Insert a
straightened paper clip, needle or similar object into the vent hole.
This will push the material into the die body. The debris can then
be easily removed by cleaning the inside of the die using a patch
saturated with
Outers
Solvent. Reassemble the die.
PREPARING YOUR CASES
All cases must be sized
and trimmed to the same
overall length.
For the
best results, full-length
resize each case and trim
to .020” under maximum
case length. This is a
“one-time only”
preparation of any and all cases to
be used in the X-Sizer die.
The X-Sizer die can be
used for full-length resizing
by setting it as follows:
• Install the proper shell
holder in the ram
Photo 1
Page 5
• Adjust the mandrel so
the decapping pin extends
1/8” below
the die (see Photo 1).
• Screw the X-Sizer die
into the press until the die
touches the shell holder
when the shell holder is
brought up to the top of the
press stroke. To remove
any play in the press linkage system, lower the shell
holder and adjust the die
1/8 to 1/4 of a turn downward so the press cams
over center. Lower the press
handle all the way and note the “feel” of the cam over in the linkage. With the handle all the way down, tighten the large die lock
ring.
• Insert a
lubed
case into the shell holder and run it into the die.
• Screw the mandrel into the die until hard resistance is felt.
• Back the mandrel out 1 to 2 turns and tighten the lock nut on
the mandrel.
• With this setting, lube and resize all the cases you plan to use
in the X-Sizer die. After sizing, remove the lube and trim the cases
as directed above.
X DIE SET UP
STEP 1: Back the
mandrel out of the die until the decapping pin extends below the
base of the die approximately 1/16” to1/8”.
See photo 1.
STEP 2: Screw the X-Sizer die into the press until the die touches the shell holder when the shell holder is brought up to the top
of the press stroke. To remove any play in the press linkage system, lower the shell holder and adjust the die 1/8 to 1/4 of a turn
downward so the press cams over center. Make every effort possible
to duplicate the same amount of cam force each time the die is used.
See photo 2.
This product is covered by the RCBS Lifetime
Warranty. If you need a replacement part,
please call or write Customer Service
1-800-533-5000

STEP 3: Tighten the large lock
nut. Insert one of your sized,
decapped, trimmed and lubed
cases into the shell holder and run
the case into the die as is done in
full length sizing.
See photo 3
.
STEP 4: With the case fully
inserted into the die, screw the
mandrel into the die until hard
resistance is met. Approximately
four turns of threads will be left on
the mandrel above the lock nut.
See
photo 4
. Tighten the lock nut on the
mandrel.
Note:
Maintain this setup throughout the entire life of the cases in
this trimmed lot.
STEP 5: Reinsert a case in the
die and check for any bulging on
the case by:
1) Comparing with photo #5.
2) Chamber the first few cases at
the beginning of the loading session. If
the cases don’t chamber (due to
bulging), the mandrel is too far
down in the die. (You will need to
repeat Step 4). Size cases as you
would with any full length sizer die.
Note:
Adjusting the mandrel too far
down will cause the case to buckle.
If the mandrel is not adjusted far
enough, it will allow the cases to
continue growing. Die adjustment
explained in step 2 is very important to achieve consistent results.
Cases sized in the X-Sizer die will
have growth of a few thousandths
of an inch during the first few sizings until each case seats against
the mandrel stop.

shoulder area in the case on
