N0t a snow goose but here is a local canada on a nest sporting a lovely yellow necklace.-Surprised the local kids haven't nicked her with a rifle and taken that collar yet. . .Hevi Bismuth manufactered by Hevi Shot is made specifically for old firearms-"safe for modern and classic firearms." I use it in my 16gauge winchester. It is very expensive, probably wouldn't use it for snow geese, but for a trophy waterfowl trip it is excellent
