Description
THESE KITS WERE DESIGNED TO WORK WITH MITUTOYO CALIPERS, BUT DO NOT INCLUDE THEM. OTHER CALIPERS MAY FIT, BUT ARE NOT GUARANTEED.
GENERAL CONSTRUCTION
To make these measurement gauges, they all needed to be the same. Exactly the same. And they had to stay that way. All of these parts are made on our world-class DMG Mori lathes, from American steel, cut with reamers for consistency, and then nitrided to help them last a lifetime.
HEADSPACE GAUGES
Headspace gauges don’t need the be complicated, they just need to be correct, and exceedingly consistent. This led us to a traditional datum-style gauge – as we believe it provides the most true measurement – cut with a reamer to keep our diameter, face, and radius as consistent as possible. Again, this is in an effort to allow you to compare your measurements with someone from North Dakota or Nevada or the Netherlands, knowing that the numbers on your caliper mean something.
Included Sizes: .330, .350, .375, .400, .420, Rimfire
BULLET OGIVE
This one is a little more intricate. While most ogive comparators work on a standard datum measurement, like our headspace gauges, we thought there was a much more appropriate way to measure the ogive of a bullet. We have designed and are using custom tooling that allows us to replicate the lead area of your barrel’s chamber (if it has the standard 1.5* lead). The goal here is to allow you to measure seating depth and jump the only way that it matters, and that’s relative to your chamber. This will reduce the large swings in gauge readings from one projectile class to another, allowing you to see what really matters.
Included Bullet Calibers: 22cal, 6mm, 6.5mm, 7mm, 30cal, 338cal
