Thanks gentlemen for the replies. So as guessed the Hollywood pistols using cartridges are either similar looking models or historical inaccuracies.

I can't imagine many actors or directors coping with scenes looking a revolvers cylinder with powder, ball and caps. I watched one Civil War movie where one woman instructed another how to load a muzzle loading. Tip some random amount of powder down the barrel. Put in a ball. Ramrod it down. No wads. Pull the hammer back and you're ready! The cap was obviously too difficult. Probably too dangerous as actors might shoot someone ...

Very information the Josey Wales/Bill Wilson comments. Always amazing t how informative and what personal connections our NE members have. Thanks.
