If you purchase black powder buy the GOEX "Old Eysenford" It is faster and much cleaner than standard GOEX. A 50 shot clays course is easy with light fouling. I use 1.5 FG in the 12 and 16 gauges. Unless you are a re-loader, the RST shells are the way to go. I shoot a bunch of black powder loads in my guns and they perform as well as smokeless and are great fun to use in the old guns!
