All my barrels shoot minute of angle or better at 300 yards. At 100 yards they do better than MOA. Green Mountain made the barrels. I love the quality and performance I am getting. I shoot reloads and factory loads. You could have a bad hinge pin or forearm making to much contact with the barrel. I shoot off a Sinclair rest and do not touch the gun except for the trigger an a light cheek contact. Again mine have the PLASTIC STOCKS. I hope you find your problem.

SHOOT STRAIGHT AND OFTEN. Hunt with your kids. Teach them not to shoot anything that they are not going to eat. Have respect for all ANIMALS.
