Overview

This modified brass case is intended for use with the Hornady Lock-N-Load Overall Length Gauge, helping reloaders measure bullet relationship to the lands of a barrel. It is a specialized component for those working on cartridge setup and seating depth with compatible Hornady equipment sold separately. The case features a flash hole cut out and threads added for gauge use, making it a purpose-built tool rather than a standard loading component. Supplied in a 50-count package, it suits reloaders who want multiple cases on hand for repeated measurements.
