The RCBS Trim Mate Case Prep Centre helps to make the tedious tasks of chamfering, deburring, primer pocket cleaning, military crimp removal and flash hole deburring quick and effortless.

The 5 gear driven heads turn each tool so all the reloader has to do is hold the brass at the appropriate location until they are satisfied with the results.

These accessories make the RCBS Trim Mate Case Prep Centre a more versatile machine to meet many case prep requirements.

Primer pocket uniformers are designed to ensure that primer pockets are cut to the correct SAAMI depth specifications, cleaning out built up carbon residue from previous firings and squaring the bottom of the primer pocket with respect to the case head. This step is important as variations in the seating depth of the primer can change how the firing pin strikes the primer producing inconsistent ignition.
