A little more info is needed really. What type of gun and when it was made would be helpful. The lead shot ban has been in place since 1988 or 89. I do not know of any guns made since then that are not safe to use steel shot. If your shotgun is older than that you may want check further. Even if it was made after 1989 steel shot is not recommended with full choke tubes. Steel shot generally patterns tighter anyway so a standard modified tube will pattern about like a full choke tube if you are shooting steel shot. An IC tube will patern like a modified tube.
