Hornady Primer Pocket Reamer Small Multi-Caliber Steel Reamer Head

The Hornady Primer Pocket Reamer is a steel replacement reamer head designed to remove the military primer-pocket crimp from GI brass and clear residual powder fouling, prepping small primer pockets for uniform, reliable primer seating.

This is the small reamer head only - multi-caliber in use and finished in silver for quick visual ID against the large-primer version - and it threads onto standard Hornady hand-held or motorized primer pocket reamer handles via its 8-32 thread. It quickly converts crimped military brass into reload-ready case mouths and smooths once-fired pockets for consistent ignition.

Designed as a replacement or backup cutter for Hornady's Primer Pocket Reamer system, the 390750 is a must-have for any reloader's bench that processes military-surplus or once-fired small-primer brass.
