The ML smoothbore could be loaded with about anything. In the later years many came with a wad punch to cut out wads. Paper and cardboard may ahve not been all that readily available in the early years as today. I have heard of the use of leaves, cloth, wasp nests, leather etc for wads. Performance wise the early smoothbore could not have been up to todays standards. They used cast, hobbed or Rupert type shot makers, some did not even try for roundness. Also the shot sizes tended to be larger, maybe BB size more or less. It was not untill after the very early 1800's that shot towers existed in the US. England had them about 1790. Hunting with shot often meant waiting for the game to group up to get the most for the least unless one was wealthy. Today we use cotton for patching, yesteryear they may used more linen and leather which is a little tougher.
