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

The Hornady B234 Lock-N-Load Comparator is a precision reloading tool designed to measure bullet ogive dimensions for consistent, accurate handloads. This set pairs the Lock-N-Load Comparator body with six caliber-specific inserts in the most popular rifle bullet diameters: .224, .243, .257, .264, .277, and .284. By measuring from the bullet ogive rather than the case head, reloaders can standardize seating depth across every loaded round and eliminate one of the largest sources of handload inconsistency.

Uniform seating depth translates directly into tighter groups downrange and more predictable pressure curves. The interchangeable inserts thread into the comparator body, which mounts in a standard caliper, so every round is checked against the same reference point regardless of who is on the bench. The set's primary function is to improve accuracy in any precision rifle reloading workflow.

Designed for use across all calibers within the included insert range, this Set of 6 weighs approximately 1 lb and is a versatile bench accessory that swaps quickly between bullet diameters as you change projectiles. Whether loading for varmint rifles, big-game hunting, or precision match applications, the Hornady Lock-N-Load Comparator gives you the measurement consistency to get the most out of every component.
