The Superior Precision Cartridge Gauge allows you to measure two critical dimensions of a rimless cartridge:
-the distance from the case shoulder datum to the bullet datum
(where the bullet diameter is equal to the bore), and
-the distance from the case shoulder datum to the case base
(which is the required headspace).
You will need a quality caliper or equivalent, you can use a 6” caliper for most cartridges.
The Superior Precision Cartridge Gauge is made of stainless steel.
