Lee Bullet Sizing Kits provide the quickest and easiest method for sizing cast bullets. Designed with standard 7/8-14 threads, these kits are compatible with any single-stage reloading press. The bullets are pushed through the sizing die nose-first, eliminating the need for special nose punches. Gas checks are automatically seated and crimped into place, enhancing efficiency. The 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. Intended exclusively for single-stage presses, the push-through punch replaces the shell holder in the ram. Since Lee does not make top punches for molds, none are required with this kit. To crimp gas checks, first lubricate the bullets with liquid Alox, place a gas check on the base of the bullet and set it on the punch. As the bullet passes through the sizing die, it will be sized and the gas check securely crimped in place.
