My $0.02: Stick to Cowboy Loads
I have thought about your question myself.
I can not point to any specific resource, other than the manufacture's instructions and warnings, so please take this as my opinion only . . .
Even though a ROA is built to modern tolerances and with quality steel, it was not indented to withstand the unique stress and pressures associated with modern smokeless propellants.
I use the conversion cylinder for my ROA to get me though the months I do not have access to an outdoor range to simulate shooting a black powder revolver, not as a replacement for a single action center fire revolver. Given the cost of conversion cylinder, I would opt for buying a center fire revolver to shoot standard ammunition.
