I assume that you have the hunter barrel with the faster rifling twist that they are made to shoot bullets, but will shoot balls with lighter powder charges. The regular barrel has a 1 in 66" twist that shoots round balls great. A round ball out of a .50 will get most jobs done if you do your part. I have taken many whitetails with a .495 round ball, some as far as 110 yards, and got complete pass through of the chest. A .495 ball weighs around 180g of pure lead, so it sticks together and expands very well. I shoot nothing but round balls, but have moved up to a .54 just because I wanted a new rifle.
