Product Summary
The Hornady Lock-N-Load Bullet Comparator Insert is a caliber-specific component designed for reloaders seeking ultimate precision in ammunition preparation. This specific insert is sized for .257 diameter bullets, allowing you to measure seating depth from the bullet ogive to the base of the loaded round. By measuring from the ogive, which has minimal variation, you can effectively eliminate inconsistencies in seating depth. This insert must be used in conjunction with the Hornady Lock-N-Load Bullet Comparator and the Overall Length Gauge (sold separately) to achieve accurate results.
