If your shell holders don't securely grip the shell and firmly fit into the press during reloading, you're bound to have headspace and sizing problems. At RCBS we manufacture our shell holders to the industry's tightest tolerances, using only the finest steel.

Shell Holder Rams and Adapters permit the use of RCBS Shell Holders on the presses indicated. Clip spring holds Shell Holder in place, yet allows rotation to any convenient angle.
