Lyman .243 Win Case Length Headspace Gauge

Description

Lyman’s case length/headspace gauge for .243 Winchester provides a simple, mechanical check of resized bottleneck rifle cases to help ensure proper headspace dimensions. After resizing, the reloader inserts a case into the gauge to confirm it does not exceed the maximum or fall below the minimum allowable headspace. The gauge also identifies cases that exceed the maximum allowable case length so they can be removed from service. Follow the manufacturer’s safety guidance if a case measures out of specification.
