RE: having muzzle loader trouble
I have a Traditions Buckhunter that wouldn't group at all at 100 yards. Shooting at a cardboard covered pallet it would put shots at random all over the target with the 240 grain Hornady XTP Sabots. My dad happened to have some 460 grain Great Plains conicals with him. I loaded them up with 100 grains of Pyrodex Select and shot a 1.5" 3 shot group right off the bat (I got lucky).
Muzzleloaders seem to be very picky eaters sometimes. My Traditions will only shoot heavy conicals. My Knight DISC shoots 235 grain .40cal QT's very well, but not the 300 grain PTX .45 cal sabots (1-2" groups vs. 3-4" groups).
Just a matter of finding out what your rifle likes.
I do have to ask too, are you shooting off of a rest or freehand? I don't want to insult your intelligence, but I've seen guys try to sight in a scope shooting offhand and blame the rifle. Shoot from a stable benchrest until the rifle groups point-of-aim/point-of-impact. THEN practice from the freehand shooting positions.
Good luck,
Mike
