RCBS 90379 Primer Pocket Uniformer Small Multi-Caliber

The RCBS 90379 Primer Pocket Uniformer is a precision case-preparation tool designed to true and square the primer pocket wall and bottom on reloaded brass. Manufactured with carbide cutters, the uniformer produces a consistent depth and surface across the primer pocket so new primers seat reliably and at the correct height round after round.

This is the Small size, intended for small primer pockets across a wide range of common bottleneck and straight-wall cases in multi-caliber handloading applications. The shank is machined from steel with a durable black finish, and the cutter head is sized to clean and uniform the pocket without removing excessive material from the case head.

Used as part of the standard case-prep workflow after resizing and trimming, the RCBS Primer Pocket Uniformer is a staple on the handloading bench for reloaders who want consistent primer seating, reliable ignition, and tight case-prep standards. Sold as a single unit.
