RCBS 90383 Carbide Primer Pocket Uniformer Large Pistol

The RCBS 90383 Carbide Primer Pocket Uniformer is a precision case-prep tool designed to clean and standardize Large Pistol primer pockets on reloading brass. Built around durable carbide cutters, it removes built-up carbon residue and trues the primer pocket wall and bottom to consistent SAAMI depth and width specifications, so fresh large-pistol primers seat properly round after round.

The uniformer is built around a standard 8-32 thread pitch that mates with common case-prep handles on the loading bench. With the uniformer installed, a few controlled turns clean and square the pocket in a single pass. Metal construction with a black finish gives it the durability to stand up to repeated high-volume case prep.

Sold one uniformer per package, the RCBS 90383 is the carbide-cutter option for reloaders who want consistent primer seating across their large-pistol brass.
