I have a 12ga sxs muzzleloader with cylinder bore barrels. I am going to cast soft lead slugs that I will size to about 0.722", these are a little tight but will go down the bore. I am thinking about trying these slugs without an over powder wad, just a thin over shot card to keep the slug seated. I have seen many claim any air gap is a bad deal with BP. Anyone ever try this? Not looking for speculation as to what may occur, I have Google if I want that.
