Buy on Ammo Depot

The Lee Precision Breech Lock Bullet Sizer Kit is a reloading accessory that sizes cast bullets nose-first, so no special nose punches are needed. Its push-through punch replaces the shell holder in the ram, and the kit automatically seats and crimps gas checks in place while a special container captures the finished bullets.

Built with standard 7/8x14" threads, the kit fits any single stage reloading press. For cast bullets, select a sizing kit .001" larger than the groove diameter; liquid alox lubrication is sold separately.
