According to the dimensions a go gauge should protrude from the chamber between .133 and .134. I assume this is a barrel nut type prefit, not shouldered. A go gauge should typically not protrude any further than the highest point on the bolt, in some bolts it may be the extractor or bolt nose,to the bolt face plus .010inches for clearance between the bolt and breech face. For comparison a Remington 700 pattern breech allows the gauge/case to protrude between. 154 and .155 and I would consider that to be the maximum allowance before the webbing is exposed and allows undue stretching or even splitting at the base.
