RE: Remington 1100 Question
Head,
Go to the remington site. You can purchase a steel shot barrel that was made to shoot 3" steel shells out of a standard receiver. They come with a full choke, but you can purchase additional choke tubes. They also have them in Cabelas, and you can read the explanation. On a standard receiver, the steel shot barrel can shoot heavy 2 3/4" and steel 3". Out of a magnum receiver, you can shoot 3" steel or 3" lead.
