Let me start off by saying that this is my first season to duck hunt, and I don't know a great deal about it. My question pertains to this...I have an older model Remington 1100 12-gauge shotgun that is pretty old. By old, I mean at least 17+ years old. In order to change the choke on the shotgun, I have to change out the barrels. Is it o.k. to shoot steel shot from this gun, or do I need a special barrel that is designed to handle steel shot? Thanks.
