Lyman 30-06 Springfield Case Length/Headspace Gauge Steel

The Lyman 30-06 Springfield Case Length/Headspace Gauge is a precision reloading tool built to verify that resized brass falls within SAAMI-spec acceptable headspace and case length limits before it goes back into the chamber. Machined from steel and made in the USA, this dedicated go/no-go gauge is caliber-specific to the 30-06 Springfield.

Using the gauge is straightforward: the reloader simply inserts a fired, resized case into the gauge to confirm it does not exceed the maximum allowable headspace or fall below the minimum. Cases that run too long stretch the chamber and can cause hard extraction, pressure problems, or other unsafe conditions, so the Lyman gauge gives a quick, reliable check during the case prep stage of handloading. Because it is dedicated to a single cartridge, the dimensions are exact for 30-06 Springfield brass rather than an approximation.

A simple, durable bench tool, this gauge belongs in any handloader's shop setup. Designed and built by Lyman, a long-trusted name in reloading equipment, the 30-06 Springfield case length/headspace gauge is an affordable accessory that helps ensure safe, consistent reloads round after round.
