Hornady B234 Lock-N-Load Bullet Comparator Set

Improve bullet seating consistency and cartridge measurement accuracy with the Hornady B234 Lock-N-Load Bullet Comparator Set. Designed for use with the Hornady Precision Measurement Station, these comparators help evaluate the distance from the base of a bullet to its ogive. Measuring from the ogive provides a more useful reference point than measuring from the bullet tip, helping reloaders achieve consistent bullet seating depth and more uniform ammunition performance.
The Hornady B234 comparator set is intended primarily for comparing bullet base-to-ogive measurements across a range of common calibers. It can also be used for cartridge measurements, although cartridge case designs vary and some cases may not be ideally suited to the comparators included with the Precision Measurement Station. For cartridges where the case mouth bottoms out on the standard comparators, Hornady recommends using the compatible original-style bullet comparators in this set for improved measurement flexibility.
This Hornady comparator set is a practical addition to precision reloading equipment for shooters who want repeatable measurements during load development and ammunition preparation. The included caliber options support common bullet diameters, including .224, .243, .257, .264, .277, .284, and .308. Use the appropriate comparator insert for the bullet being measured, and pair the set with compatible Hornady measurement equipment to streamline setup verification, seating-depth checks, and accuracy-focused reloading tasks.
