What is the difference in a .490 round ball and a .509 and which is easer to load and more accurate

[Slamfire]

.490 round balls are patched. The ball never touches the barrel, but the patchin' gives it the rotation. .509 sounds like a lead conical size, they engrave at loadin' for the most part, and don't use a patch. What yore riflegun likes best will depend in part on the twist rate of the riflin'.
