PRODUCT INSTRUCTIONS
SAFETY
Reloading is an enjoyable and rewarding hobby that can be conducted safely. But carelessness or negligence can make reloading hazardous. This product has been designed from the
beginning with the user’s safety in mind.
When reloading, some 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 operating of the tool. Don’t take shortcuts.
• 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. Develop
a reloading routine to avoid mistakes. Avoid haste — load at a leisurely pace.
• Always wear adequate eye protection.
• If any unusual resistance is encountered when moving the operating handle, STOP IMMEDIATELY and
investigate the cause. To proceed against unusual resistance may damage equipment and/or cause
serious personal injury!
LOADING DATA
• Use only laboratory tested reloading data. We highly recommend the use of the SPEER Reloading
Manual or RCBS.load reloading software.
• OBSERVE ALL WARNINGS 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.
• DO NOT use primers of unknown identity.
• Keep primers in original factory container until ready to use. Return unused primers to the same factory
packaging for safety and to preserve their identity.
• 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 use any powder unless its identity is positively known. Discard all mixed powders and those
of uncertain or unknown 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.
• Before charging cases, settle the powder in the powder hopper. Load and check the weight of at least
ten charges. This will assure you that the correct powder charge is being loaded.
• After a reloading session ends, pour the remaining powder back in its original factory container. This
will preserve the identity and shelf life of the powder.
• DO NOT smoke while handling powder or primers.
RECORD KEEPING
• Keep complete record 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.
Since RCBS has no control over the choice of components, the manner in which they are assembled, the
use of this press, or the firearms in which the resulting ammunition may be used, no responsibility, either
expressed or implied, is assumed for the use of ammunition reloaded with this press.
INTRODUCTION
The Rock Chucker Supreme Press has been designed specifically for heavy-duty reloading,
case forming, and bullet swaging. It is engineered to handle the largest and longest magnums
down to .17 caliber. The compound leverage system of the Rock Chucker Supreme Press can fulllength resize cases with less effort than other presses neck size. Using RCBS Case Forming Dies
this press will form .30-06 cases into many other calibers.
By combining the famous RCBS block “O” frame with the compound leverage system, the
Rock Chucker Supreme will develop work pressure that would spring other presses out of alignment. To insure alignment under these pressures, the Rock Chucker press frame provides a full
four inches of ram-bearing surface to rigidly support the one inch diameter main ram. The
compound leverage action is similar to that of a power punch press. As the handle pressure
increases, the leverage is compounded, building up a maximum work pressure in the main ram as
it travels the full length of the stroke. The toggle block, links and pins are engineered to withstand
the punishment of heavy-duty reloading. The handle is made of solid steel and features a comfortable ball-type handle grip. The Rock Chucker Supreme Press has standard 7/8-14 thread for most
popular reloading dies and accessories.
ACCESSORIES
The Rock Chucker Supreme Press is designed to utilize a primer arm. This priming system is
equipped with interchangeable primer plugs and sleeves for seating large and small primers.
The Primer Catcher keeps spent primers from dropping to the floor and is easily removed for
emptying.

INSTALLATION
Mount the Rock Chucker Supreme Press to a sturdy workbench or table with two 3/8” bolts of
sufficient length to penetrate the press base and bench.
Attach the handle nut to handle. Install the threaded portion of the handle to either the right or
left side of the toggle block and lock down with the handle nut. See photo #1. The handle nut must
remain tight at all times to avoid damage to the handle and toggle.
Install the Primer Arm as show in photo #2.
Slip the primer catcher between the ram and rear portion of the frame. Snap the feet of the
primer catcher into slots on the side of the press frame. See photo #3.
The Rock Chucker Supreme press ram accepts removable type shell holders. To install, insert
the shell holder into the ram and twist slightly to the left. To remove, twist slightly to the right. See
photo #4.
WARNING
TO AVOID INJURY, READ AND FOLLOW THESE SAFE PRIMING PRACTICES.
DO NOT ATTEMPT TO PRIME MILITARY CARTRIDGE CASES WITH CRIMPED PRIMER
POCKETS UNTIL THE CRIMP HAS BEEN REMOVED WITH A COUNTER SINK, A
SPECIAL REAMER OR BY SWAGING. PRIMERS SEATED INTO CRIMPED POCKETS
ARE SUBJECT TO DEFORMATION WHICH CAN CAUSE MISFIRES AND EVEN
DETONATION DURING SEATING WHICH CAN CAUSE SERIOUS PERSONAL INJURY.
DO NOT ATTEMPT TO SEAT PRIMERS AGAINST EXCESSIVE RESISTANCE WHICH
MIGHT CAUSE DETONATION AND POSSIBLE SERIOUS PERSONAL INJURY. CHECK
TO BE CERTAIN THAT THE CASE WAS NOT PREVIOUSLY PRIMED, THAT THE FIRED
PRIMER WAS REMOVED, THAT A PORTION OF THE PRIMER CUP WALL MIGHT STILL
BE IN THE PRIMER POCKET AND THAT YOU ARE USING THE CORRECT SIZE PRIMER.
DO NOT MODIFY THE PRIMING SYSTEM IN ANY MANNER OR ATTEMPT TO USE
SIMILAR PARTS OR PRIMING SYSTEMS FROM OTHER MANUFACTURER’S. TO DO SO
COULD RESULT IN PRIMER DETONATIONS RESULTING IN SERIOUS PERSONAL
INJURY.
NEVER SEAT A PRIMER INTO A POWDER CHARGED CASE.
DECAPPING LIVE PRIMERS IS EXTREMELY DANGEROUS AND IS NOT
RECOMMENDED.
PRIMING
To use the primer arm, first make sure the correct size primer plug and sleeve are in position.
To install the primer plug and sleeve, drop the primer plug through the sleeve. Place the spring on
the primer arm body. Thread the plug and sleeve into the primer arm body and tighten the
assembly with a small nail or paper clip through the cross hole in the primer plug. Do not over
tighten. Check from time to time to be sure the primer plug remains tight.
Insert lubed case into shell holder, lower the press handle to size the case and remove the
spent primer. To prime, simply place the correct size primer, anvil side up, into the primer sleeve.
See photo #5. Then, gently and slowly raise the press handle. As the case is drawn out of the die,
the primer arm will guide into the slot in the ram, the case will be lowered onto the live primer,
seating it to the bottom of the primer pocket. See photo #6.
After the primer is seated, lower the press handle enough to allow removal of the case from the
shell holder. Be sure not to lower the handle too far or the decapping pin in the die will push the
live primer back out. Always inspect the primed case to make certain the primer is properly seated.
The Rock Chucker Supreme does not accept the Auto Primer Feed accessory (9550, 9580).
MAINTENANCE
This press was lubricated at the factory. However, it is necessary to lubricate all moving parts
from time to time with gun oil. If rust spots appear, swab lightly with gun oil and wipe dry. Care
should be taken not to apply oil where it could come in contact with primer pockets or primers. Oil
will deactivate primers. It is a good practice to clean the press prior to lubrication to remove grit
and other residue. You will note ease at which the epoxy enamel paint wipes clean. This finish is
impervious to oil and is extremely chip and fade resistant.
