I have had some problems with steel shot. It doesn't have any knockdown power. My buddy and I both use steel for ducks and geese. Last time we went out we buckled a mallard anda goose in the airbut was unable to bring it down. They flew off like nothing happened. I am looking into bismuth I have heard some really good things about it. What areyou shooting at ducks and geese. I will be sooting a 3" shell.
