I figured I would ask on the forums about this problem since I have never dealt with this issue before. I recently purchased a Christensen Arms 300 Win Mag. It is a very lightweight rifle even with the scope and bipod. It came with a muzzle brake installed. It is ported every direction and is lifting the rifle off the ground when I fire it. I'm having a difficult time even getting a 1MOA group and I have tried numerous reloads different case lengths you name it I have tried it. I am now thinking the problem might be muzzle brake related. I'm guessing that the rifle is shifting before the bullet even leaves the barrel. I shoot with brakes on many rifles but have never seen them jump around like this. Hoping someone has had this issue and might be able to give me some possible solutions before I have to buy a different style of brake. Thanks
