I have an older Knight muzzleloader (50 cal) with the 209 conversion primer kit installed. I have been using 2-50g Pyrodex pellets with the 250g Knight Red Hot Sabots since I bought it years ago. I am out of the Red Hots and have never tried any other bullets. It shoots ok groups and have been interested in the 245g AeroTIp Powerbelts. I also have looked at the Hornady L-N-L Sabots with 250g SST bullets. Anyone have any experience with these? Could I have improved accuracy with the Powerbelts or SST's?
