I went to the range today after putting in asuper full choke. I shot at 25 yards and the majority of the pattern is about 4 to 5 inches to the left. Then I shot at 50 yards and there was only about 20 holes.I am thinking that it could be a foot or more to the left.what should i do to fix this? Or how far right would you aim? I am not looking to shoot 50 yards but would like to shoot 35 to 40.

Thanks
