Go / No Go guage for primer pockets?

[22to45]

If you were making a guage, what size would it be. There has to be an easier way than checking with a primer. Am specifically thinking about large rifle size primers.

Personaly, I use the shank on a number drill. I'm not in my shop right this moment, and I don't remember which one off the top of my head as I don't do it that often. But if I remember correctly the drill I use is .209 thousands in diameter.

There is probably better ways to measure the pockets properly, but I get by on tools I already own, plus my own inovations, as I'm not a smith. One day, I hope.

I use my fingers as a gauge, if I can push them in with my fingers, they're done. Or if banging it on the edge of the table lets the primer drop out, they're done.

Bit excessive. The bench rest guys don't even go that far.

I have a lathe and could easily turn a gauge.. I thought maybe someone had a size. I have done all the tests to see if they will stay in...

Maybe use a case with an slightly loose pocket measure it for the for the "no go" gauge. I just mark any cases that feel loose with a "discard" in marker and throw them out after using them a last time for practice but I use a hand held tool to insert primers.

I have a couple of gauges that a board member makes and sells (but his name escapes me). Their use is pointless IMO - I bought them on a whim. Using them is very much by "feel", i.e. when it's "easy" to insert, the primer pocket is loose. As discussed, once you can force a primer in by pushing, it's time to crush and discard after the next use.
