Overview

This modified case is intended for use with Hornady Lock-N-Load O.A.L. gauges when working with 30-06 Springfield chambers. It provides a chamber-specific setup option for shooters who are measuring cartridge overall length as part of load development or rifle setup. Manufactured to SAAMI specs, it is designed to fit into Hornady’s gauge system rather than serve as a standalone component. Calipers are not included, and the gauge itself must be selected separately as C1000 or C1550.
