Well, I just bought an M2 American and a HeviShot 13 choke. Also bought a box of the Magnum Blend Ammo 3".
Shot it last night and pattern was 3-4 inches left at 30 yards...
Thought it might be shells, so I tried some Winchester Supreme 5s. Still left...
Tried some number 8s at 12 yards...Still left.
Got mad and went home...
Today, after thinking on it some, want to try another choke and will borrow a buddy's JH and give that a shot.
If it's still left, I'm not sure what I will do...If it straightens it out, I may be cutting somebody a heck of a good deal on a choke...
Will try and post pics tomorrow of the targets.
If anybody has any advice on the left issues, please let me know...
