Ensure maximum safety and precision with Lyman's rifle case length/headspace gauge. After resizing, it's crucial to verify that your bottleneck rifle cases maintain the correct headspace dimension. With Lyman's easy-to-use gauge, you can quickly check that each case falls within the acceptable range of headspace, both maximum and minimum. The gauge also identifies cases that exceed the maximum allowable length. Cases with excessive headspace should be destroyed to avoid unsafe reloading. Lyman's gauges remove the uncertainty from the reloading process, providing reloaders with confidence in every shot.
