Being European modern re-proof means I'm willing to pay extra for ole' grand daddy gun so tested. Able to shoot modern ammo of appropriate pressure is big plus. In America people collect guns and sometimes shoot them knowing that "Model T can't be driven at 80mph w/o engine blowing long before that speed is attained". Americans have RST and Polywad catering to people shooting antiques w/o modern re-proof. When recommending light weight game gun on European forums the likely candidates are vertical guns from Beretta, B.C. Miroku and if looks are acceptable Merkel Bros. it is almost never something real old with short chambers or twist or damascus barrels. The gold standard for SxS classic is Webley & Scott 700 series from Birmingham sadly discontinued many years ago. There are suitable copies from Germany, Italy, Austria, France, Spain,..... Limited new SxS game guns means Fabrique en Turkye. Different worlds different beliefs and customs.
