Achieving optimal safety and accuracy during rifle reloading starts with ensuring the proper headspace dimension. Lyman's case length/headspace gauge makes this process effortless. Simply insert your resized bottleneck rifle case into the gauge to verify that the headspace stays within the specified minimum and maximum tolerances. The gauge also detects any case that exceeds the allowable length. If any case shows excessive headspace, it should be discarded immediately to maintain safety. With Lyman's case length/headspace gauges, you can trust that every reload is as precise and reliable as the last, eliminating guesswork and improving consistency.
