Hornady Lock-N-Load Headspace Kit W/Body

The Lock-N-Load Headspace Comparator extends brass life, improves accuracy, and enhances safety. The gauge measures variations in brass before and after firing or re-sizing. It allows for headspace comparison between fire-formed brass and re-sized brass. The included bushings provide the ability to check most bottleneck cases from .17 Rem through belted magnums.
