I did some work on custom 300 and 338 RUMs. These were straight from the gunsmith and both guns would not chamber the go gauge. I don't know how the smith determined the headspace, but they weren't even close. I pushed the headspace forward to chamber the go gauge and both worked fine after that. They were both tight chambers but both worked fine.
I think this is another example of the lack of machining knowledge that the self proclaimed gunsmith have. Find a reputable smith and have them check the chamber.
