I've been loading blackpowder shells for Skeet and Sporting Clays for quite sometime and have settled on Remington Gunclubs,any primer, 70 grs. 3f Goex and 1 oz. shot. The hammergun I use patterns better with card wads than plastic wads, the way I load the plastic is over a nitro card and I haven't noticed any melting. In the matches I shoot only the hull can be plastic so I didn't see any point in adjusting the choke for the TGT wad. During a 100 bird Sporting clay round I use an unlubed felt wad and spray a few shots of soapy water down each barrel after leaveing the station by the time it is my turn again the water has drained out of the barrels and the fouling is soft.
