I've never shot steel in any S x S except my old BSS. I never really cared if it was approved by Browning for it, in fact, I always was told it wasn't. Didn't matter, I believed it would handle it and it has. Most of what has been shot out of it is 2s, 3s and 4s.

Worth Matthewson wrote in BIG DECEMBER CANVASBACKS that he shot a L C Smith for several years, with nothing but steel. It developed an issue unrelated to the loads he used and he carried it to his gunsmith, who informed him the chokes in it were Xfull and Xfull. The old gun had handled big steel shot for years through those tight chokes without any damage whatsoever.
