RCBS Trim Mate Case Prep Center Military Crimp Remover - Large Size

The RCBS Trim Mate Case Prep Center Military Crimp Remover in large size is a dedicated tool for reloaders who process military brass with crimped primer pockets. If you reload vintage military ammunition, pick up Lake City or other mil-spec brass, or work with calibers commonly loaded in military rounds, this attachment addresses one of the biggest headaches in case prep: safely and efficiently removing the crimp without removing excess brass from the pocket itself. Military-crimped primers sit tight, and the wrong approach can waste usable brass or create inconsistent pocket dimensions that compromise accuracy and seating.

The large-size Trim Mate works as part of the RCBS case preparation system, allowing you to handle the crimp-removal step before trimming, chamfering, and deburring. The redesigned tool operates at two speeds, giving you control over removal rate and helping you preserve case life—a real advantage when good brass is scarce or expensive. For high-volume loaders working with military surplus or government-issued cartridge cases, this tool turns a tedious, high-waste step into a manageable part of your prep routine.

RCBS has been the backbone of reloading shops since 1943, and their case-preparation lineup reflects decades of feedback from precision shooters and volume reloaders alike. Consistent case prep is non-negotiable if you want consistent velocity, accuracy, and brass longevity. The Trim Mate Military Crimp Remover lets you standardize that step so your handloads shoot tight and your brass lasts.
