I recently purchased a 535 Waterfowl/turkey combo. I shot some turkey loads out of the turkey barrel and loved the gun. My questions are though that when i bought it at Dicks sporting goods, no one knew anything about the gun. I would like to know if the chokes and barrels that came with the gun can handle steel shot? Could i use the turkey barrel for anything other than the turkey choke? Will the other choke tubes fit in it? Can any of the barrel's/ chokes handle non-toxic's such as hevi shot or bismuth? What is the biggest shot that can go through each choke? Lead and steel. Thanks for the help and sorry if its really newb or has been posted already, its my first post/time on the forum.
