I would really like to know the formula you have for figuring the yeild of a 1/4-28 bolt?
I've always ran 65 in/lbs on action guard screws that are bottoming out solid on a pillar and a bedded action. If this was a plastic, wood or fiberglass stock with no pillars or beding the torque value would change as the material can be compressed. 40 in/lbs to me is too light.
