I used the same wads as 2-piper only in 10 ga. For muzzleloaders we used to order the "10 ga for brass" diameter. Followed V.M. Starr's recommendation of chewing on the 1/8" card over powder wads to get a little saliva on the edges to reduce fowling during continual shooting. Ever tried reloading a ML double while standing in three feet of water with waves coming through the bulrushes?
