Overview

Built for handloaders working with cast bullets, this sizing kit is designed to size bullets and also seat and crimp gas checks. It fits any standard 7/8x14 thread reloading press, making it a practical addition to a compatible bench setup. Lee Liquid Alox and a reloading press are required and sold separately, and users of the Automatic Processing Press (APP) will need to provide their own catch container. As with any reloading component, consult your reloading manual or the powder manufacturer’s website for load data before use.
