The Lee Sizing Kit in .339 caliber (Lee part no. 90576) is built to be the fastest, easiest way to size cast bullets on the bench. It uses standard 7/8×14 threads, so it fits any reloading press, and bullets are pushed through the die nose first, eliminating the need for special nose punches. Gas checks are automatically seated and crimped in place during the same pass, and sized bullets collect in a dedicated container so they’re ready to load. Lee lube is sold separately.
