Description
Lyman’s Rifle Case Length Headspace Gauge for 6.5 Creedmoor (brand part no. 7990346) is built for the safety and accuracy check Lyman recommends after resizing any bottleneck rifle case: verifying that proper headspace dimension has been maintained. The reloader simply inserts the resized case into the gauge to confirm it doesn’t exceed the maximum or fall below the minimum allowable headspace, and the same gauge identifies a case that exceeds the maximum allowable case length. Lyman cautions that any case found with excessive headspace should be destroyed immediately rather than loaded. For reloaders standardized on Lyman case-prep gear, this reloading gauge is a critical safety check for 6.5 Creedmoor brass after resizing.
