After resizing bottleneck rifle cases, it's essential to verify that the headspace is within the correct range for safe and accurate reloading. Lyman's case length/headspace gauge makes this process simple and reliable. Just insert your resized case, and the gauge will instantly show whether the headspace meets the minimum and maximum allowable limits. The gauge also identifies any cases that exceed the maximum allowable case length. In the event that excessive headspace is detected, discard the case immediately. Lyman's gauges offer the precision and peace of mind needed to ensure your reloads are safe and accurate.
