Recently our illustrious legislature has introduced legislation to ban lead ammo for hunting and this time there's a good chance it will pass. Since most of my hunting is will small game, these days I use a shotgun and since most of my guns are older, steel shot is out. I have some bismuth shot on hand, right now #6 and I plan on getting some #7, but going through my loading data for shotgun ammo, everything I have is for lead. I have a hard time finding load info for bismuth, is it that much different than loading for lead?
