THESE KITS WERE DESIGNED TO WORK WITH MITUTOYO CALIPERS, BUT DO NOT INCLUDE THEM. OTHER CALIPERS MAY FIT, BUT ARE NOT GUARANTEED.
As long as any of us have been reloading, we have been using comparators. These are simple items meant to let us measure seating depth and headspace between cases. If you reload alone, always use the same components and calibers, and don’t tinker around, these are a solid option.
Really though, that’s not us. We like to use different components, we like to compare, and we want to know that the measurements we are taking are a little more than relative. This is why we are making our ZERO measurement gauges.
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.
