Lee Bullet Sizing Kits provide the fastest and easiest way to size cast bullets, offering a convenient solution for reloaders. 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. Additionally, gas checks are automatically seated and crimped into place for added convenience. Sized bullets are captured in a special container, ensuring an organized workspace. Each kit is complete for one bullet size, with the press and bullet lubricant sold separately. Intended for use on single-stage presses only, the push-through punch replaces the shell holder in the ram and no top punch is required, as Lee does not make top punches for molds. To crimp gas checks, simply 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 will be securely crimped in place.
