I would start with a Uberti 1851 Navy in .36
Throw away the factory nipples the moment you take it out of the box. Buy some Treso or Slixx Shot nipples.

My SlixxShot nipples were made to fit Remington #10’s, but they are not being made any longer so you need to make sure they fit the CCI caps that are still available. Luckily I bought 1000 of the Remington caps years ago and still have several hundred left.
You can thank me later. The factory cones are garbage. With SlixxShot nipples and the caps designed the fit them perfectly misfires and cap jams are near a non-issue.
Check out Duelist Den on YouTube. A few hours of his videos and you willl have near 100% confidence before you set out for your first range trip. He’s the man when it comes to all things black powder.
Cap and ball revolvers are a blast. They are accurate even by modern standards. I really enjoy mine.
I have a Uberti 1851 Colt .36 and a Pietta 1858 Remington .44
Both are a blast but the .36 is my favorite. It’s very accurate, shoots to point of aim perfectly and it’s very efficient and economical to shoot. I can plonk with 15g of powder.
I go on a hunting trip every year and carry my Colt Navy revolver on my hip the entire week. It’s no Glock 17, but I don’t feel unarmed with it either.
Shooting round ball is a blast. You will enjoy it.
I don’t make paper cartridges for my cap and ball guns, I load them powder and ball. Do make paper cartridges for my brown Bess. I load 100g of black powder, a .69 ball, and three 00 buck pellets. It’s a blast to shoot.
My Pietta and Uberti are both good to go. I think either brand is good to go.
