Give this a try the courtney, I shot a tighter pattern using this load. 120gr of Triple7 FFG, 300 gr.Hornady .451 HG bullets and Knight .451 sabot sleeve (their black). I was using the powerbelt but thought they were going in to easy down the barrel. They weren't grouping like I wanted them to. After each shot I used two pre-lube patch from T/C in the barrel, one to get heavy powder residue and second one to finish it off. Give it a try. I just sighted my gun in on Tuesday around noon and took this 157lb. 8 point by 3:45
