I am up to 5 and enjoy all of them! For Black Powder loads: 2&3/4 chambers use Federal paper with two and a half or three drams of GOEX 2 FG, 1 or 1&1/8 oz. shot and fold crimp. 2&1/2 use trimmed Federal paper with the same charges and the same shot amount and roll crimper. Wad column is hard nitro cards with fiber or felt fillers and a overshot card for the roll crimped loads. 16ga. loads is plastic hull. two and a half drams 3 FG, 7/8 oz. shot and roll crimp (New primed Cheddite hulls)nitro cards and felt filler. 10ga. uses 4 or 4&1/4 drams of GOEX 2FG, 1&1/8 or 1&1/4 oz. shot, (New primed Cheddite hulls cut to 2&7/8 inch) cards and fillers finished with a roll crimp. This is great fun and shooters are really surprised when any of these loads touch off! I usually shoot 2 stations with light smokeless loads to clean out the tubes (or you can just brush) during a round of 50 clays. Having the maximum amount of fun is a requirement!
