I've got quite a number of pre 64s, all shoot consistently under an inch for me except a FW and it no longer lives here. I tighten the front screw hard, hard. Then I snug the rear screw and only tighten the middle screw to the point the floor plate will close right. My thought process is that tightening front and rear a set torque value works only if the action is bedded perfectly. If it isn't bedded perfectly, tightening them the same can only torque the action which I don't think is conducive to accuracy. I sincerely doubt these factory stocks are bedded all that well. Others will probably find different methods that work for them, this is only what I have experienced.
