Measuring cartridge lengths across the bullet tips is not a reliable (or repeatable) method for measuring your loaded rounds. It is not uncommon for variations of up to .025" to exist from one round to the next when measured across the bullet tips. Bullet tips vary considerably due to the way in which bullets are made. Stoney Point Bullet Comparator solves that problem by measuring your rounds from a reliable surface on the bullet - the ogive - to provide consistent, precise measurements of your rounds. The Bullet Comparator is also used by many shooters to check uniformity of bullets - from base to ogive - which is critical to accuracy
Stoney Point Bullet Comparator easily attaches to the blade of your caliper with a thumbscrew and uses interchangeable insert bushings to measure from the bullet ogive. These bushings are available in fourteen (14) sizes from .17 caliber to .45 caliber.
Used in conjunction with the Stoney Point OAL Gauge, the Bullet Comparator by StoneyPoint provides the ultimate in precision measurement. Stoney-Point Bullet Comparator will properly align the OAL Guage for proper, precise measurement using your caliper. This method allows direct comparison of your loads as you set up your bullet seating die for the correct bullet free-travel (jump).
