Lee Precision .458'' Diameter Classic Bullet Sizing Kit
The Lee Precision .458" Diameter Classic Bullet Sizing Kit is a dedicated solution for cast bullet reloaders who want speed and simplicity without the complexity of separate sizing operations. If you're casting your own .458-caliber projectiles—whether for big-bore rifles, pistol cartridges, or specialty loads—this sizing kit handles the critical process of bringing cast bullets to uniform diameter and seating gas checks in a single, press-mounted step.
What sets this kit apart is its straightforward design: bullets feed nose-first through the sizing die, eliminating the need for special nose punches or fussy alignment. Gas checks are automatically seated and crimped as the bullet passes through, saving you a separate setup. The kit threads onto any single-stage reloading press using standard 7–8x14" threads, and sized bullets drop directly into the included capture container for easy collection. It's a no-fuss approach to getting cast lead projectiles to spec without the extra steps or tooling.
Designed expressly for single-stage press operation, this kit is complete for sizing one diameter—you'll need your own press and bullet lubricant (liquid alox is recommended for gas-check seating). Choose the .458" sizing die if your cast bullets measure .457" at the groove diameter, following Lee's standard practice of sizing .001" larger than the mold's bore. It's the kind of straightforward, effective tool that appeals to handloaders who value function over frills and want to maximize every casting session.
