I've done a hundred or so savage barrels and I still only use a go gauge & scotch tape & feel. Recently I headspace my 5 different 6.5 Creeds as close as I could get them by "feel" so I could use the same reloading die setting. Couldn't do it, one was .0005 off.
Not sure how he does it. There is a Forster set that comes in .001 increments. The difference between go and no is .006 in his .223 I believe. I personally try for the middle but I have a few that are on the loose end of the spectrum for use in places with things that bite back. Honestly I think the loose ones are more accurate.

I wish I could set brass up to resize to within a half a thou of headspace consistently and measure it accurately. A little too much lube, a speck of crud, etc., and I’m out.
