So I’m chambering a 30 Sherman to you with. Chamber is perfect per the supplied gauge, which is lasered “Manson-30 Sherman Magnum”. Bolt falls closed on it, can be closed with moderate effort with a .0015” piece of scotch tape on it. After torquing, should have about .0005 clearance on the Go gauge.
Thing is, it falls closed on a piece of either loaded factory 300 PRC ammo or Hornady PRC brass. It occurred to me that possibly I was supposed to chamber short on this gauge, but I have a SAAMI 300 PRC gauge and it is definitely longer than the one for the 30 Sherman. What would y’all advise to do? I can take material off the shoulder and tenon to problem, just want to do the right thing.
