Ensure the highest level of safety and accuracy with Lyman's case length/headspace gauge. After resizing your bottleneck rifle cases, simply insert them into the gauge to confirm that they meet the proper headspace dimensions. This critical step helps ensure that the headspace stays within the safe and correct range. Additionally, the gauge will highlight any cases that exceed the maximum case length. If excessive headspace is detected, discard the case immediately. Lyman's gauges remove all uncertainty, providing reloaders with the confidence that their cases are ready for reloading.
