You can use conical bullets in cap and ballers too. I don't remember the velocities possible but the conical bullets are quite a bit heavier than round balls.
Yes, they are, but people don't realize the effectiveness of just plain old lead round balls. Elmer Keith had it on good authority from folks who were there that they were preferred by many lawmen and such in the Old West, due to observing their superior effectiveness, even over conicals.
