Sense I don't cast lead I am in the need of a source for round balls. Do any of you know where I can buy hard cast (WW or harder) balls to use in my full bore (.690) double shotgun? I'm not sure but I think about .685 or slightly smaller will do. I will be using plastic wads reversed with petals trimed back to about 3/8". I also intend to use a black powder substitute.
