TDB, I make gages in thousands, from .015 below a go-gage chamber to infinity but to be more practical a gage that is .011 over go-gage chamber, the .011 over fits my M1917 Eddystone and it fits Mr Smith's Eddystone in Bradford PA. but before you are convinced it is possible someone that can not do it will convince you they can not do it, and sure enough-they can't.
As a thought, gages could cost $15.00-up, if you purchase a go-gage (useless), you have a go-gage that will verify the gage will chamber in a go-gage size chamber, we all knew that before it was purchased, it will not tell you the size of the chamber in .000 thousands, the go-gage can be turned into a go-to infinity gage but that would take years to explain and even longer for most to get used to the ideal.
Three gages, 223, 30/06 and 308 Winchester at $15.00-up is going to cost $45.00-up plus shipping etc., and all the gages are going to tell you is 'your rifle will chamber a go-gage'.
'A' good use of a go-gage is to use it as a transfer gage to adjust a die, shell holder and press for sizing, a feeler gage can be used to verify the go-gage.
