My Grandfather who taught me to shoot muzzle loaders 60 years ago and made all his own stuff including powder used a balance scale he said to use at least one half the weight of a ball that caliber and not more than 3/4 the weight of a ball that caliber and that the was what he used for all bullets in that caliber muzzle loader. He started with 1/2 the ball weight and when he got a tight group he quit if he got to 3/4 of the ball weight for that caliber he started over with a different bullet or patch or bigger ball. Lee
