First off, the choke is too much as you already know. Did the gun not come with any other chokes? What shells are you shooting? If you are tearing them up so bad, I would assume that you are using turkey loads and are too close. I would get some 1-1/4oz Rabbit and Squirrel loads of 5's or 6's and if you are not able to get another choke right now, I would just back off on the distance and that should help you out for a minute.
