Deplorable Wrote:Great info, thanks Klem. In this case, the bolt is a 0.125". Do you think a finishing hand reamer would still be applicable? Or would a 0.136" bolt be more likely to work? (I'm worried about misfires if the gun really needs a 0.125", as another commentator pointed out. But if it in fact needs a 0.136" then that shouldn't be a problem)
If you currently cannot close a GO gauge on a .125" bolt then either the chamber needs to be lengthened, or the bolt deepened. The quickest way to do this is to use a .136 bolt which will lengthen the headspace by .011" (see my Post#10). The GO gauge will definitely close on a .136" but also make sure the NO GO still does not close before firing.
