Overview

This sizing kit is intended for reloaders who want to size cast bullets and also seat and crimp gas checks as part of their loading process. It fits standard 7/8x14 thread reloading presses, making it a practical addition to a compatible bench setup. Use requires Lee Liquid Alox and a reloading press, both sold separately, and APP users will need to provide their own catch container. As with any reloading component, load data should be verified through a reloading manual or powder manufacturer’s website.

  • Requires a standard 7/8x14 thread reloading press, so it is not a standalone sizing solution.
  • Lee Liquid Alox and a reloading press are required and sold separately, adding to the total setup cost.
  • If used on the Automatic Processing Press (APP), a separate catch container must be supplied by the customer.
  • Users still need to consult a reloading manual or powder manufacturer data for load information; the kit does not replace load development guidance.
