Hornady B14 Lock-N-Load Bullet Comparator Set with 14 Inserts

The Hornady B14 Lock-N-Load Bullet Comparator Set provides a consistent, repeatable way to measure loaded ammunition and individual bullets. Measuring cartridge overall length across bullet tips can produce unreliable results because bullet tips often vary from round to round. This comparator measures from the bullet ogive, a more uniform reference surface, helping reloaders achieve precise and consistent seating-depth measurements.
The comparator body attaches easily to the blade of a compatible caliper using the included thumbscrew. Interchangeable inserts allow the same tool to measure bullets across 14 popular diameters, making it a practical addition to a multi-caliber reloading setup. By referencing the ogive instead of the tip, the Hornady Bullet Comparator helps identify seating-depth differences and supports more consistent cartridge preparation.
The B14 set includes the comparator body and inserts for .172, .204, .224, .243, .257, .264, .277, .284, .308, .338, .358, .375, .416, and .458 caliber bullets. It can also be used to check bullet uniformity from the base to the ogive. Constructed from metal with a silver and red finish, this Hornady comparator set is designed for measuring and comparing bullets and loaded rounds in precision reloading applications. The set is compatible with 14 calibers and is supplied as one complete kit.
