Good write up. I'll just throw out that by far most of the troubles I've seen from scope mounting have been in the base to receiver area. I mounted a 20 moa rail on a friend's savage 110 300 win mag about a year ago, degreased everything with acetone, blue loctite, and torqued to spec with a torque wrench. It shot loose after about 1000 rounds of 215 berger hybrids. It got put back on with red loctite.
