Gunsmithing No Go Guage rigged

[Acer76]

I’ve seen where guys talk about using tape on a Go Guage to rig a No Go. Can anyone comment on how reliable or responsible this is? Kind enough to post pics and descriptions, how to (save some $$)?

It’s as simple as it sounds. Check that the go chambers. Tape the back of the gauge(trim the overhang), and try again. The difference between a go and a no-go gauge is usually about .004”. Ideally the tape would be that same thickness or a shade thicker.

Good enough. No need for any body waste time posting pics. Thank you.

If you're working with a SAAMI chamber then you have about a .010" range on headspace, which really only matters if you're shooting factory ammunition. If you hand load then it doesn't make much difference since you'd be tailoring the case to fit the chamber anyway.

I've used tape on a go-gauge. It works well enough and seems repeatable depending on your methodology. They make peel-to-thickness-shim stock too if Scotch Tape is too ghetto for you.

I do it, put a piece of over the back, slide a razor around the edge and you have a perfect go gauge +.002"
A no go is usually .004" over so this makes it a hair tighter but Im fine with that.
Closes on the go and not on anything longer = perfect

I've seen people use an unfired case as a go and tape as no go. But these are wildcat people that have forgotten more about reloading than I will ever know.

I have a few cases filled with epoxy that I use as gauges. The $20 gauge at Brownells is very hard to crush, but takes a few days to turn up.
