You might make this inquiry with the guys who regularly shoot trap and skeet with muzzleloaders in the NMLRA shoots. They certainly get decent performance there. I know some only use a card over blackpowder, then shot and a thin over shot card. Others use just a thin fiber wad over the powder or a card with half a fiber wad over the powder. All of this indicates considerable experimentation to determine the best load for a specific barrel. I learned a flintlock double 16ga sure makes skeet a whole new game. Have to know ALL about follow through!
