Lyman's rifle case length/headspace gauge is the perfect tool to ensure your reloaded ammunition meets the highest standards of safety and precision. After resizing bottleneck rifle cases, simply place them in the gauge to verify that the headspace is within safe and accurate dimensions. The gauge also helps detect any cases that exceed the maximum permissible length. If excessive headspace is detected, it's crucial to destroy the case immediately. With Lyman's case length/headspace gauge, you eliminate any guesswork and ensure your reloads are consistent and safe for optimal performance.
