I have had good experiences with the Mossberg 500 series shotguns, some of the older ones had a problem with the safety button shooting loose but that was solved with a dab of lock tite, I think the factory is doing that now. The forearms tend to rattle but that is easily solved by hanging on to it when you need it to be quite, I have also seen people make shims out of foam tape to quite them down but that is minor. The only real gripe I have had with Mossberg turkey guns is the choke tube, my recommendation would be to put that tube in your junk box and go buy a hastings, briley, carlsons, whoever, anybodies but Mossberg's and give it another try. As far as ammo goes, a buddy of mine who turkey hunts with a 20 ga. has had really good results with the Winchester supreme #6s, he shoots the 3" loads but I think it is offered in a 2 3/4" load also. His kill zone pattern density is a lot better than a lot of 12 gauge guns and after all it is not the number of shot in the shell but the number of shot in the head and neck that kills the bird. Good luck
