I found this video very interesting and put it in the handgun section as it seemed to pertain. The first half of the video is the most interesting as that tells you how to make the cartridges which honestly looks like a lot of work. I have little interest in prepared cartridges for a revolver except for my unhistorical method of using plastic tubes for skirmishing. I hope some of you with more patience and time than I have will try some and report back here with your results.
