The HORNADY Lock-N-Load Bullet Comparator Set with Body (HK66) is a great tool for increasing the accuracy of your loaded ammunition. The Head-space 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. Bushings fit the comparator body and attach to calipers with a thumb screw. Can be used with bottleneck cases from 17 caliber through large belted magnums.
