My rifle is in 7 PRC. I can't get dependable accuracy. Usually around 2-3 MOA. My next thought is to glass bed it, but I also feel I shouldn't have to do so as the receiver mates up against the stock's aluminum insert. Is it common to bed a stock with an aluminum chassis? The Ruger has the angled front receiver screw which should pull down and back into the chassis. Just spitballing here as I have fired several hundred rounds trying to find something accurate.
