Whatever your political beliefs about centralized government, one thing that the European and British countries have that ours really needs is the concept of "proof". No firearm can be sold or resold without documentation that it its "proofed" for appropriate loads. This is established by government certified Proof Houses. Britain has one in Birmingham and, I believe, another in or around London. The firearms that I am involved with importing will have been legally sold in Britain as proofed for nitro loads. That doesn't mean that some ham-handed idiot with delusions of nuclear power can jam in High-base short magnum shells and expect to keep his face attached to the front of his head for any length of time. They will be proofed for modern, low-base, smokeless loads and perfectly safe so long as those are what you intend to shoot in them. As an example, I find that 1 oz or 7/8 oz international trap loads will kill any upland bird within 25 yards very handily. That is the kind of load these guns will be proofed for. I would strongly advise against trying to take them out for late pheasant in South Dakota where the ranges are long and you are shooting at the birds well-armored backs. On the other hand, dove, quail, early pheasant, chukar, partridge, cottontail and squirrel are all well within the capability of low-base loads. You could even use them on decoyed duck if your calling is really good and you can get them in really close. (Personally, I find that a double gun in a duck blind is a pain and prefer a good pumpgun, like a Winchester M12.) The bad reputation that old guns have is due to the low quality of Damascus steel that was used by inexpensive European guns and almost all American ones. Making Damascus steel was an artisan skill that our industrial production methods weren't up to so the vast majority of American Damascus barreled shotguns were made with lower grade Belgian barrels imported for that purpose. Those are only safe with black powder and even then should be checked out by a qualified smith. I recommend Dale Tate or Steven Dodd Hughes. Additionally, though most folks don't know this, by 1890 fluid steel had come onto the market and that kind of barrel is most definitely safe with smokeless loads so long as there is enough steel still wrapped around the chambers. Proof houses make sure that there is before allowing such guns to go on the market. A goodly number of these "antiques" will have been "sleeved" meaning that the original barrels had gotten too thin and were cut off. Then the chambers were reamed out and new barrels slipped into the chambers and braised or silver soldered in place. Properly done this is just as strong as a modern barrel and absolutely invisible. That does not change their status. Legally, a gun is the action. The stock is a handle and barrels are interchangeable so if the action was built "in or before 1898" it's an antique, not a firearm. It still goes BOOM when you pull the trigger but it's not a firearm. Ah, Congress! Y'gotta love'em.
