Lee Bullet Sizing Kits offer the fastest and simplest solution for sizing cast bullets. Designed with standard 7/8-14 threads, these kits are compatible with any single-stage reloading press. The unique push-through design allows bullets to be sized nose-first, eliminating the need for special nose punches. Gas checks are automatically seated and crimped into place, streamlining the reloading process. Sized bullets are captured in a special container for easy collection. Each kit is complete for one bullet size, with the press and bullet lubricant sold separately. The kit is intended for single-stage presses only and the included push-through punch replaces the shell holder in the ram. Since Lee does not produce top punches for molds, this kit does not require one. For crimping gas checks, simply lubricate the bullets with liquid Alox, add the gas check to the bullet base and set the bullet on the punch. As the bullet passes through the sizing die, it will be sized and the gas check will be crimped securely in place.
