25cal PMA Bullet Comparator

Now made by PMA Tool. 

In 2024 we bought out the remaining inventory of Davidson Seating Depth Checkers from the manufacturer and began plans to make them ourselves. It's hard to improve upon the Davidson, but we've made a few anyway. In order to give them a better and more uniform finish, we made them from larger stock and turned every surface, we've added large laser engraved markings to differentiate between sizes and we've improved the inside chamfers and tapers. We've also added a few sizes that have been unavailable for years. We are offering the PMA Bullet Comparators in 17, 20, 22, 6mm, 25, 6.5mm, .27, 7mm, and 30 caliber sizes.

These little tools have been around the shooting community for many years. Most experienced benchrest shooters consider the Davidson checkers to be the most accurate and easiest to use of all the depth measuring tools available. These tools attach to one blade of a dial caliper, are held on to the caliper with a small thumb screw, and are now machined from stainless steel. These tools will give you a relative, comparable measurement of the bullet seating depth which will be close to the depth of the bullet on the lands of the chamber. The key word is relative, so you can accurately compare and measure changes in the seating depth of your bullets. The same comparator should always be used when making seating depth adjustments.
