When reloading bottleneck rifle cases, ensuring proper headspace is essential for both safety and accuracy. Lyman's case length/headspace gauge allows reloaders to easily check that their resized cases meet critical headspace dimensions. Insert your case into the gauge, and it will verify that the headspace doesn't exceed the maximum or drop below the minimum tolerance. The gauge also identifies any cases that are too long. If excessive headspace is detected, discard the case immediately to prevent unsafe reloading. Lyman's gauges ensure precise measurements every time, removing any uncertainty from the reloading process.
