Hornady B14 Lock-N-Load Comparator Set Silver Multi Caliber Metal

The Hornady Lock-n-Load Bullet Comparator Complete Set Body and 14 Inserts is just what you need to ensure accuracy and repeatability in measuring your cartridge lengths. It is common for cartridge lengths to vary by up to 0.025 inches and the Hornady Lock-n-Load Bullet Comparator Complete Set helps to reduce that variation. The Hornady Lock-n-Load Bullet Comparator Complete Set measures your rounds from the ogive of the bullet for maximum accuracy. Simply attach the bullet comparator tool to your caliper blade using a thumbscrew then use the correct insert to measure the bullet length from its ogive.
