First thing to understand is that all these fine old doubles are on average 75 years plus old. They need to be checked by a gunsmith that is use to working on old doubles. He can give you an expert opinion on which gun is safe to shoot. Twist, steel and damascus can all be shot, if in good safe condition. Pay just a few dollars to make sure.
Low pressure shells are recommended to keep stress low on the action, barrels and wood. A thin stock should be treated kindly just as the rest of the gun. RST makes excellent shells and should be safe to use after you have your gun checked out. A hand is a terrible thing to loose.
