The Hornady Lock-N-Load Bullet Comparator Complete Set provides an ogive-based method for measuring cartridge overall length to improve repeatability when seating bullets. The comparator attaches to the blade of your caliper via a thumbscrew and uses interchangeable inserts to measure from the bullet ogive rather than the tip. Hornady notes cartridge lengths can vary by up to 0.025 inches, and this set is designed to reduce that variation for more consistent loaded-round measurements.
