Hornady Lock-N-Load Bullet Comparator Body
The Hornady Bullet Comparator measures rounds from the ogive to provide consistent, precise measurements.
Measuring cartridge lengths across bullet tips is not a reliable or repeatable method for measuring your loaded rounds. It’s common for variations of up to .025″ to exist from one round to the next. The Hornady Bullet Comparator solves that problem by measuring rounds from a reliable surface on the bullet, the ogive, to provide consistent, precise measurements of your rounds. The Bullet Comparator is also used to check uniformity of bullets from base to ogive.
The Bullet Comparator easily attaches to the blade of your caliper with a thumbscrew and uses interchangeable inserts to measure from the bullet ogive. It requires inserts to match your caliber (sold separately).
Used in conjunction with the O.A.L. Gauge, the Bullet Comparator provides the ultimate in precision measurement. The Bullet Comparator will properly align the O.A.L. Gauge for precise measurement using a caliper. This method allows direct comparison of your loads as you set up your bullet seating die for any selected bullet free-travel (jump).
