I strongly recommend shooting power belts. They by far shoot the best out of anything we ever shot in our muzzle loaders and everyone else we know says the same. If i were u i would probably sight it about 1" or 2" high at 50 yds since ur shooting just open sights. That should put you right on at around 100yds. Thats how we have ours sighted in and it works well. Good luck
