Sharps4590: Hit a deer with a round ball and it's like shoving a broomhandle in their side, devastating. But round balls are a shorter range proposition due to ballistic shape, and the old knuckleball flight. Would be great if a plastic or felt wad vane could be attached to the rear side to give it a shuttlecock effect. You may have to use an overshot card to get a suitable crimp. BPI has more experience with round balls and lots of formulas. Steve
