In the warning Browning issues about not shooting steel in their classic Belgian-made guns (A-5, Superposed, Liege, Double Auto), they refer to the ring bulge that might result as a cosmetic issue. I've often wondered whether a ring bulge might pop the ribs, at which point it goes a good bit beyond "cosmetic". The only reference I can recall seeing about that possibility goes back to the early days of steel, when the wads didn't offer the same degree of protection as they do now. But I still wonder . . . Anyone ever hear of a ring bulge in the choke area popping the ribs??
