Hornady Lock-N-Load Headspace Gauge 5 Bushing Set with Comparator

The Hornady Lock-N-Load Headspace Gauge is a great tool for increasing the accuracy of your loaded ammunition. The Headspace gauge measures from the case-head to the datum line on the case shoulder to allow proper brass resizing for a precise fit with the rifle chamber.
