What kind of shot can I shoot besides lead thru my 1965 Belgian auto 5 12ga? Mine is a Magnum auto-5 and I was thinking about wingmaster HD. Is this gonna be safe thru this shotgun? It has a fixed Full choke 32inch barrel. I can shoot lead legally when hunting turres from a boat but otherwise it's strictly non-toxic. I am eventually gonna pick up a Japanese barrell, but for now I am stuck with what I got.
