Overview

This sizing kit is intended for reloaders who want to size cast bullets and seat or crimp gas checks using a standard 7/8x14 thread reloading press. It requires Lee Liquid Alox and a reloading press to be used, and those items are sold separately. For use on the Automatic Processing Press (APP), a separate catch container must be provided. It is a straightforward bench tool for handloaders working with cast bullet preparation and should be used alongside verified load data from a reloading manual or powder manufacturer.

  • If used on the Automatic Processing Press (APP), a catch container must be supplied by the customer.
  • Intended for .358" bullet sizing, so it is a caliber-specific kit rather than a universal option.
  • Load data is not included; users are directed to consult a reloading manual or powder manufacturer website.
