Measuring cartridge lengths across 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 wich bullets are made.
Our 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, wich is critical to accuracy.

The Bullet Comparator easily attaches to the blade of your caliper with a thumbscrew and uses interchangeable inserts to measure from the bullet ogive.
These bushings are available in fourteen different sizes from .17 caliber to .45 caliber.
