I may have bought a new/unfired Pietta 1858 in .44, with a conversion cylinder to .44 Colt. I have to fess up, I originally thought it was a .45 Colt conversion. I know it couldn't be, but nevertheless, my word is good, so I may be the new owner of this handgun. I hadn't planned on getting into black powder right now, if so, I have a buddy that's selling an unfired 1858 Pietta in .36 caliber that he'll practically give me. Okay, I'm rambling. If I wind up with this revolver, my immediate plan would be to use the conversion cylinder in it and shoot .44 Colt ammo. I don't reload at this time, and may not be able to get into it for quite some time if at all. Here's a question for you black powder experts. Can I shoot something like Black Hills or Ultramax smokeless Cowboy loads or does it have to be black powder only? I'd also appreciate any insight you can give me into this revolver and caliber in general. I'm familiar with and own modern revolvers, but I'm a complete rookie at black powder stuff. BTW, I can pick up the .36 cal Pietta for $150. Should I get it? Thank you gentlemen.
