skyler - keep the powder charge around 50-70 grains and the rifle might surprise you how well it will shoot roundball. There is an old myth that a fast twist barrel will not shoot roundball. That is not always true. Granted they will not shoot as well as say a 1-66 or 1-70 twist, but if you keep the powder charges low, the ball will not skip the rifling and I have seen and own even a 1-28 twist rifle have excellent accuracy with roundball.
