I have similar results using 90 rains purodex, 1- .125 op wad, 1- 1/2 inch lubed cushion wad, 1.5 oz shot, and a os card. I love my TK 2000 too. I also have a decent 00 buckshot load up to 50 yards. 120 gr, 2- op wads, 1- .5 inch cushion wad, 15-00 buckshot with equal volumn of buffer, and a thin os card
