I have "rolled" my own cartridges from good ole cigarett paper. I have done both .36 and .44. I used them for civil war reenacting for reloading in the field on the move, takes just a few seconds to load the cylinder, but easy to drop in the grass and hard to find due to coloration and small size. From a stable place it's fine. I found that it's best to use a piano wire nipple pick to pierce thru the nipple otherwise you can have a delayed reaction snap-pause-pause boom. But if your taking that long to load you might as well just make pre-made tubes like a musket and rip and pour in the chamber then ball it. Or just carry an extra cylinder loaded but uncapped(like I do now). If you can't get the job done with 10-12 shots you might as well quit. If your at a range just do the powder, felt wad. bullet of choice, and then cap it off. A fast time reloading usually is not needed unless your in some kind of speed reloading competition. Not only that how long does it take you to make a individual cartridge 5 minutes? How about a pack of 6? I can reload my .44cal, powder, felt, bullet and cap in less than 5 minutes for the whole cylinder. I don't want to spend a couple of hours makeing cartridges before I go out to the range, it takes the pleasure out of it for the day when I know I have to spend an hour or more just in prep. I owuld rather grab my stuff from the cabinet load it in the range box and head out the range.
I don't carry a single shot pistol so it might work out better, making cartridges.
