My goose gun is an old model 12, 3 in. with a Polly Choke. I tried the BC in it, shot 2 shells and got 2 geese. They were real close, but they are the first 2 geese I ever killed with steel. I jump shoot geese and do real well with the SUPPER HIGH DOLLAR stuff, but with steel all I`ve ever been able to get is feathers. Jury is still out on BC for me, but I do know that I would reather be shooting lead.
