I have a marlin xs7 in 7mm-08 and I have out about 200 rounds through it. I have cleaned it and taken good care of it. I have changed the stock and floated the barrel, and even bedded the wood stock and I cannot seem to hold a good group under 1.5-2MOA. I have tried several different boxes of ammo, checked scope, rings and rail and action screws. Everything has the correct torque settings. I cannot figure out what is going on. I have never had this issue with any other rifle. Is this normal? Any thoughts?
