Lyman 7.62X39 Case Length/Headspace Gauge
The Lyman 7.62X39 Case Length/Headspace Gauge is a precision tool engineered for reloaders and shooters who demand consistent, safe, and reliable ammunition. Designed specifically for the 7.62x39mm bottleneck rifle cartridge, this gauge enables users to quickly verify both case length and headspace after resizing and before loading. Its primary function is to help prevent unsafe or unreliable rounds by ensuring each case meets industry-standard specifications.
Product Overview
Manufactured from durable steel, the Lyman 7.62X39 Case Length/Headspace Gauge offers a straightforward and effective method for inspecting resized cases. By simply inserting a case into the gauge, reloaders can confirm that the headspace falls within the SAAMI-specified minimum and maximum tolerances, and that the overall case length does not exceed safe limits. This tool is especially valuable for those reloading military surplus or mixed brass, where dimensional variances are common. With a compact and robust design, it is suitable for use at the bench or in the field, supporting consistent ammunition quality and improved safety during reloading operations.
