I wish there was a throat gauge, like a machined bullet to check both the chamber and throat.Best to make the case part the SAAMI max case and the throat the SAAMI min throat with appropriate tolerance. Clearance for the throat might be SAAMI minus .001" with the tolerance being -0.002 to +0.000.
The only tricky part would be cutting the body taper, shoulder, and throat taper. That said, a decent machinist could probably cut his first one from 1/2" aluminum or brass stock in about an hour on a traditional lathe. After that, the time needed might drop.
A guy or gal with a CNC could do the set-up in probably the same time, and then it's off to the races if modest production is the goal.
Someone on a different thread mentioned the 3-D printers storming the market recently. They might even be less expensive to produce for modest production runs. This might be a perfect marketing toe in the water for this kind of limited use end-user gauging. If it doesn't pass the plastic gauge test, it's off to the gunsmith for checking with a proper gauge!
