Hornady Lock-N-Load Bullet Comparator Set of 6 - B234

This bullet comparator attachment measures loaded cartridge lengths from the bullet's ogive rather than the tip, eliminating variations up to .025" that occur with traditional measurement methods. The basic set includes a comparator body and 6 interchangeable insert bushings covering calibers from .17 to .45. It attaches to caliper blades with a thumbscrew and is also used to check bullet uniformity from base to ogive.
