I love the TK2000! I start with 100 grains of T7 fffg. Then a wad, to protect the shotcup from heat, and melting. Then, a 3.5 shot cup, filled with copper plated #5's. To top it off, another shot wad. Oh yea, I forgot to mention, I also use a cushion wad, in the shot cup. I cannot reveal the info on this, copyright reasons. I am still looking to make some profit from this discovery!!
