Bismuth is right there with lead in the periodical table of elements, almost if not damn exact charachteristics of lead as far as performance, the difference being is that it is not toxic such as lead. I shot some 3in bismuth 2's on some geese early on the season, I can't really ever remember seeing canadians crumple like that. It was amazing in the difference, those geese folded like a champ, but at 2 bucks a shot, I gotta find another way to get em, dead is dead, but more impressive with loads like bismuth, just too $$$$$$$
