There really wasn't much out there before the 22 cb in the Smith and Wesson for pistols. They were more of a parlour pistol meant for shooting in the house like a game of loud darts.
Then after a few years during the American Civil War there were some 32 rimfire pistols and in rifles there were the Volcanic and the Spencers, neither one of those firing a very impressive load, compared to today.
There were pinfire cartridges, and a few paper or linen cartridges that were used in the 1869 (iirc) Sharps rifles.
I've heard mention of some experimental rubber cartridges in the 1830's or 40's, but with the technology of the day they weren't successful.
It was after the American Civil War that self contained cartridges started to become popular and the loose powder and ball muzzleloaders began to be replaced.
In Europe I think that a style of cartridge and gun called the "Flobert" was in vogue around that time.
I'm going off of memory, and am too lazy to go look up the exact facts, but this should get you close with a bit of Googling.
Hope this helps.
