Just a thought, how are you torquing your action screws?
There's a particular way the Rugers are supposed to be torqued. I don't recall the exact method and specs, but someone will bring it up. I do recall the front screw is supposed to have the most torque, the rear, "some", and the middle, just barely enough not to fall out. Too much on the middle screw can play havoc on accuracy from what I understand.
