i shoot anything as far as size from bbb-2shot nothing smaller than 2s all my hunting buddys do the same and we have never had any trouble but i wouldnt try it with cheap factory choke tubes like the thin walled mossburg tubes or the browning thin walled ones but have used the rem factory tube . i use to shoot a sp 10 with bbbs all the time and used heavy shot alot till it went through the roof. now its 1187 supermag 30in wuth rhino full tube awsome results. divers are hard to keep down but if hit with a tight choke its over im going to try some black cloud when i get done with this case of kent.
