Lyman Case Length/Headspace Gauge

To achieve the highest degree of safety and accuracy, Lyman recommends that all bottleneck rifle cases be inspected after resizing to ensure the proper headspace dimension is maintained. The Lyman Case Length/Headspace Gauge provides a quick insert-and-check method to verify that brass meets minimum/maximum headspace specifications and does not exceed maximum case length. The gauge identifies cases that are too long or outside headspace tolerance before they reach your chamber. Precision machined by Lyman Products, this essential gunsmithing tool helps protect you and your firearms while maintaining consistent performance. Included components: Headspace Gauge.
