Mine was a Ruger M77 in 270WSM that I bought last year, couldn't really remark on groups cuz after having to hit the bolt with a 2x4 to open it after firing the first round I am pretty sure I knocked the scope off! Seriously though it came from the factory with a sharp burr in the chamber and the brass would bite into the burr when fired so I couldn't extract a round without force. Took it back to the store I bought it (SW)from and made them take it back, no repair needed just give me my money back!
