The Lee Precision Breech Lock Bullet Sizer Kit provides a dedicated solution for sizing cast bullets on single-stage reloading presses. It uses a push-through punch system so bullets are sized nose-first without requiring special nose punches. The kit also seats and crimps gas checks automatically and collects sized bullets in a built-in container.
