same here, that and SD. Largest legal lead shot for turkeys in Wisconsin is #4s. I too would assume, that they are old goose loads from the days when lead was legal. I bet they'd blow the hell outta grapefruit and melons tho.............
BB is good for geese and high ducks. Won't be much left of small puddles ducks afterwards but still a good round. I use BBB for high geese in high winds but BB works too.
And various household appliances. I was out shootin stuff at the dump becuase I happen to be a hillbilly and my cousin and I absolutely destroyed an old junker dryer along with a couple fridges and a stove with 3 inch magnum #2s.
