Thanks to all replies. I just spent the past two hours trying replacing the shims, little to no change. I have not shot the factory choke yet,but I shot a true glo choke and it was the same results. I guess ill try the adjustable sights. It's just frustrating having a new gun shoot poorly. By the way, had a friend shoot it and center of pattern was more to the center of the target. So I guess it's just how the gun fits me.
