Lyman recommends that all bottleneck rifle cases be inspected after resizing to ensure proper headspace dimension is maintained. The most effective way to verify this critical dimension is with a Lyman case length/headspace gauge. Simply insert the case into the gauge to confirm it does not exceed the maximum or fall below the minimum allowable headspace, and the gauge will identify cases which exceed the maximum allowable case length.
