Lock-N-Load® Bullet Comparator

Measuring cartridge lengths across the bullet tips is not a reliable (or repeatable) method for measuring loaded rounds. Its common for variations of up to .025" to exist from one round to the next. Our Bullet Comparator measures rounds from the ogive to provide consistent, precise measurements. You can also use it to check uniformity of bullets from base to ogive.

Our Bullet Comparator easily attaches to the blade of your caliper and uses interchangeable inserts (available in sizes from .17 caliber to .45 caliber) to measure from the bullet ogive.

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).

Lock-N-Load® Bullet Comparator Inserts

Item #117

Bullet Comparator Inserts are designed for use with the Lock-N-Load® Bullet Comparator; it eliminates variables when measuring the over-all length of a bullet. Bullet length can vary a few thousandths due to material variation and tip finish.

The Lock-N-Load® Bullet Comparator Inserts allow the reloader to measure the bullet from the base to a specific point on the ogive, which has little variation, if any. This versatile system also provides the reloader with a much more consistent way to monitor the overall length of their reloads, allowing the reloader to build more precision into their handloads, that translates into better groups at the range and more meat in the freezer.
