Hi all, well I've taken the plunge and picked up a used Uberti 1858. Unfortunately my range is closed for maintanance for a few weeks so won't get to play with it for a little while.
Have got a couple of questions if any of you guys can help.
First, how much is a spare cylinder for one of these? Is it worth getting one? Does it have to be a Uberti or will other makes fit?
Second, one of the nipples doesn't seem to screw in fully and there seems to be a sort of bobble on the internal thread. Does anyone know what the size / pitch of the thread is so I can get a tap to clean it out?

Thanks all, safe shooting

Keith
