Overview

This interchangeable pilot is made for use with the Hornady Cam Lock Trimmer when trimming cases in .410" / 41 caliber applications. It serves as a sizing component rather than a standalone tool, helping you match the trimmer to the case dimensions you need. For reloaders who already use Hornady’s Cam Lock Trimmer, it provides a straightforward way to set up for the appropriate caliber.
