Lee Bullet Sizing Kits provide the fastest and easiest method for sizing cast bullets. Designed with standard 7/8-14 threads, these kits fit any single-stage reloading press. Bullets are pushed through the sizing die nose-first, eliminating the need for special nose punches. The kit automatically seats and crimps gas checks in place while capturing the sized bullets in a special container for easy collection. Each kit is complete for one bullet size, with press and bullet lubricant sold separately. Intended for use only on single-stage presses, the push-through punch replaces the shell holder in the ram and no top punches are needed, as Lee does not manufacture them for molds. To crimp gas checks, simply lubricate the bullets with liquid Alox, place a gas check on the base and position the bullet on the punch. As the bullet passes through the sizing die, the bullet is sized and the gas check is crimped into place.
