I don't find the cleaning process any more difficult than with BP cartidge arms. With the OTs, just disassemble them and everything in front of the breach face goes in the soapy water. The mainframe doesn't need to be stripped except once a year, just wipe off all visible BP residue with a dampened patch. Removing and cleaning the nipples is a bit fiddly, but not difficult, but that is the only extra chore required of a percission revolver. Everything else you are already doing!
I think you owe it to yourself to give your 1860's a try.
Both the R&D and the Kirst are usually chambered in .45 Colt. Both the Schofield and Cowboy Special rounds also fit as they are shorter versions of the same basic case. O.K; The Schofield as origionally made had a wider rim for the ejection star on the S&W
