I'm thinking that there's some disagreement between your gages. That protrusion looks to be plenty more than 0.010" or even 0.015". the gages really aren't measuring the same thing- its actually surprising the GO gage doesn't poke out more.

i was not making any suppositions or claims just put the two together, dont know if it had been done
the cartridge case gauge is not a chamber, but the go, no go fit in the chamber and i thought the relationship was kind of interesting and the case in this instance it is a sized remington 3006

I've had a couple of instances where a case that fit the case gage didn't work in the rifle. Stuff like that makes me nuts thinking about it too much.

""case that fit the case gage didn't work in the riflE""
YEAH, that really can unscrew your head sometimes, and there is not practical reason for this to happen, i am going to be interested in when i get the 'field gauge' to compare them with all the rest.....
but i have had rifles that were reluctant to load 'reloads' and the reason was that there were ejection scars on the rim and the claw portion of the extractor on the bolt did not like it. at least that was the reason this time, i had to take a small file and actually file the burr away and then the bolt closed like crap thru a goose, but that was one time

I have Wilson case gauges and Forster chamber headspace gauges for both 6.5 X 55 and 8 X 57. I also have the same gauges for the 6X47 wildcat formed from .222 Rem Mag brass. All 3 sets of headspace gauges match the steps of the corresponding Wilson gauge exactly.
I would suggest that you re-examine your head space gauges and perhaps check them with a Stony point gauge to verify they are the dimensions marked on them. Based on my experience your no-go gauge is the offender.
I have numerous other Wilson gauges and find they are in very close agreement with fired cases of both known and unknown origin as well as FL sized cases from my loading dies. However I have used the Stony point gauge with my dial calipers and find it is much more useful since it allows you to adjust your loading dies to exactly match your chambers.
When you get to the 7.65 Mauser all bets are off though.
RCBS dies match the chambers and the Wilson gauges.
Several other brands of dies do not match my chambers (3) for headspace.
