Hornady B14 Lock-N-Load Bullet Comparator Complete Set Multi-Caliber Metal - 14 Inserts

The Hornady Lock-N-Load Bullet Comparator Complete Set is a precision measuring tool for handloaders who need to verify bullet seating depth from the base of the bullet to the ogive rather than the tip. Measuring to the ogive gives a true reading of how deeply the bullet sits in the case neck and is essential for consistent accuracy, especially when load development calls for seating bullets close to the lands.

The B14 complete set includes the comparator body and 14 precision bushing inserts covering bullet diameters from .17 caliber to .45 caliber. Confirmed insert sizes include .172, .204, .224 (5.56mm), .243 (6mm), .257, .264 (6.5mm), and .277, with the remaining inserts completing the set through the full range up to .45 caliber. The set works with any standard digital or dial caliper and covers the bullet diameters needed for varmint, centerfire rifle, and handgun reloading alike.

Constructed from durable metal with a silver and red finish, the Lock-N-Load comparator is built for years of bench use. Hornady's simple push-in insert design lets you swap bushings in seconds to match the bullet you are loading, making it easy to move between calibers without recalibrating.

Whether you load for precision rifle, hunting rifle, or handgun cartridges, the Lock-N-Load Bullet Comparator Complete Set delivers consistent, repeatable ogive-to-base measurements that help you get every last bit of accuracy out of your handloads.
