Overview

This sizing kit is built for reloaders who want to size cast bullets and seat or crimp gas checks on a standard 7/8x14 thread press. It is intended for use with Lee Liquid Alox and a reloading press, both sold separately, so it fits into an existing reloading setup rather than standing alone. If used on the Automatic Processing Press, a separate catch container is needed. As with any reloading component, load data should be verified through a reloading manual or powder manufacturer resources before use.
