In my Knight Wolverine .45 cal, I have tried 200 grain shockwaves, 195 grain aero tip powerbelts, and 180 grain xtp with brown knight sabot. I have varied my powder charge between 80 and 110 grains of triple seven. Nothing has provided any consistency. The Powerbelts gave me about a 10 inch group at 100 yards. After I took the scope off and put the red dot scope on, I got a 4 inch string (up and down) of shots at 100 yards with the 180 grain xtps and 90 grains of triple seven. I am wondering if the scope I am using, a Bushnell Trophy 3-9-40, is broke and is not holding zero. I bought the scope brand new, just after Christmas this year. The next projectile I will use are the No Excuse's. I have heard so many good things about them on these forums from Cayugad.
