The Hornady Lock-N-Load Bullet Comparator is perfect for the reloader looking to quickly and precisely measure seating depth of loaded ammunition from the bullet ogive to the base of the loaded round, to eliminate variation in seating depth. The comparator attaches to any caliper and measures cartridges from 17 to 45 caliber. When used in conjunction with the Hornady Lock-N-Load Overall Length Gauge (Sold Separately) you are able to determine the exact bullet seating depth for the ultimate precision.
