For shot in a choked (jug or conventional) gun, thin "B" wads for overshot, 1/8" card and 1/2" felt or donnaconna cushion wads.
For shot in a non-choked gun- likely just thin "B" overshot wads for between powder and shot and over the shot.
Lots of different guys several lots of different combinations that work for them. That is the trial and error testing to actually find what YOUR
gun prefers.
As with patched ball shooting, you have to develop the best load for your gun. Even changing shot sizes can improve or disrupt the patterns
you obtain with shot.
As to using patched round balls, you will have to develop your own load data - patch material & thickness- either 100% cotton or linen & ball diameter.
If you want to shoot hardened balls (not pure lead) then the ball will likely have to be smaller than what you would use in a pure or dead soft lead ball.
For a .58 smoothbore, something about .555" or maybe even .562" would work. You may have to buy a custom mould, like from Jeff Tanner in the UK.
A ball from .025" to .030" undersize to the bore is usually necessary to allow the use a thick enough patch, that will hold enough lube to do it's job.
3F will work, but for any given load, it will develop higher pressure that even 10gr. more of 2F. In the .58, the velocities will be similar with identical loads
using 3F or 2F. Personally I prefer the use of 2f from .50cal on up. Others use 3F in all their guns - no matter the calibre. A close friend uses 85gr. 3F in his
20 bore smooth bore and is extremely difficult to beat on a trail walk(actually, impossible so far). It is his only gun and he shoots it like a rifle inside 100yards.
Most smoothbores will be accurate enough to hunt with(with good load development, to about 50 or 60yards on big game.
Actually deliberately shooting at a paper target at 100yards should show the folly of attempting such a shot on a deer or bear.
