Product Overview
Constructed from durable steel, the Lyman 300 AAC Blackout Case Length/Headspace Gauge offers consistent, repeatable measurements for both novice and experienced reloaders.

Further Product Details
This gauge is compatible exclusively with .300 AAC Blackout brass and is intended for use after resizing operations during the reloading process. It is not designed for use with loaded ammunition or other calibers. To use, simply insert a resized case into the gauge; if the case fits flush at both ends, it meets industry-standard specifications for headspace and length. Cases that fail this check should not be loaded, as improper headspace or excessive length can lead to unsafe pressures or feeding issues.
The Lyman 300 AAC Blackout Case Length/Headspace Gauge requires minimal maintenance—occasional cleaning with a dry cloth is sufficient to remove debris. For optimal accuracy, avoid using the gauge with dirty or damaged cases. As with all reloading tools, users should follow local regulations and best practices for ammunition assembly and case disposal. Lyman provides a limited warranty covering defects in materials and workmanship; consult the manufacturer for specific warranty terms. This tool is a practical solution for reloaders seeking to enhance safety, consistency, and reliability in their 300 AAC Blackout ammunition.
