It is intended for use with ammunition made for SAAMI-standard 6mm ARC chambers.
The cartridge gauge is useful during multiple stages of the reloading process. Reloaders can use it to check resized cases, verify finished cartridges, and confirm that ammunition meets the expected chamber-fit requirements.

Use the gauge according to established reloading procedures and always follow current loading data, firearm instructions, and applicable safety practices.
Whether used as part of a new reloading setup or added to an existing collection of inspection tools, the Hornady Lock-N-Load Cartridge Gauge provides a convenient method for checking case and cartridge fit.
