You are correct !!!
I never buy a No Go gauge for that reason. it only tells you that you are beyond SAAME spec.
and the chamber should not be used.
In My opinion head space should be .0005 to .0015 for accuracy and a go gauge is the only
gauge that will tell you exactly where your chamber is at.
That just my logic for using the go gauge only.
