I'm trying to sight in my TC Renegade 54 cal. and am not having a whole lot of luck. I just pruchased a Bushnell Dusk to Dawn 1.5 to 4.5 scope, which I had bore sighted. I'm using TC Maxihunters 450 gr. and just bought Triple 7 FFG shooting 90 gr. At 25 and 50 yards I keep shooting right, no matter what I do. I'm having a hard time getting a group. I was using Goex FFG Black Powder, with the same result. I don't think I'm that bad of a shot, but maybe I am. Any suggestions!
