I am personally aware of a barrel failure on a modern Spanish double, from a very reputable maker. I'm not at liberty to say any more than that, except that it was not the result of an obstruction. I did not see the gun, but I did see the damage it did to the gun's owner. So they do happen. And depending on how one classifies "modern", those of us who have participated here for some time are well aware of failures in Ithaca Flues doubles (with fluid steel barrels)--usually very light 20's. Both cracked frames and barrel failures were involved, the usual culprit being diagnosed as ammunition producing a pressure inappropriate to the gun in question.

Anyone else remember the Remington case, or am I misremembering badly??
