The action needs to be properly bedded in the stock for a Mtn rifle to shoot well. My 1987 mtn rifle in 280 Rem was a squirrely bugger. 2+" groups at 100 yds with horizontal stringing, and mostly plus. Maybe 1-1/2" on a good day. Finally gave it a good bedding job this winter and it made a world of difference. Now it's 1 MOA with a bullet it likes.
