LOCK-N-LOAD® BULLET COMPARATOR Measuring cartridge lengths across the bullet tips is not a reliable (or repeatable) method for measuring loaded rounds. It’s common for variations of up to .025" to exist from one round to the next. Our Bullet Comparator solves that problem by measuring rounds from a reliable surface on the bullet – the ogive – to provide consistent, precise measurements. The Bullet Comparator is also used to check uniformity of bullets from base to ogive. Optional Anvil Base attaches to the caliper blade for this purpose. Anvil Base No. AB1 Our Bullet Comparator easily attaches to the blade of your caliper with a thumbscrew and uses interchangeable bushings to measure from the bullet ogive. These bushings are available in fourteen sizes from 17 caliber to 45 caliber. 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® HEADSPACE COMPARATOR
Bullet Comparator – Basic Set No. B234 Comparator body and 6 bullet inserts for bullet diameters: .224" (5.56mm), .243" (6mm), .257," .277," .284" (7mm), .308" (7.62&8mm)
The Lock-N-Load® Headspace Comparator is the best method we’ve found to extend brass life, improve accuracy, and enhance safety. The gauge measures variations in your brass before and after firing or resizing. It allows for head space comparison between fire-formed brass and your re-sized brass. Any of five interchangeable bushings are attached to your caliper using the same body as found on our Bullet Comparator. The five bushings that come with the Lock-N-Load® Headspace Comparator provide the ability to check most bottleneck cases, from 17 Rem through the belted magnums. Ackley Improved chambers use the same bushing size as the parent case. See chart provided or consult product instructions for cartridge/bushing size details.
