What I have been using, and works great for me is to make a paper cartridge out of good old post-it-note...just the right size so that a ball fits tight in it...then pour in the powder and fold over the end, and glue it down against the body of the cartridge or tube. Also fold, or "crimp" the end that the ball is in. You will make a few "lemons" at first, but then will "get your groove on" and find what works for you, and make some real nifty cartridges.
How it works in the field is that you just pop the folded end up, tear it off, pour in the powder, then just tear out the ball or squeeze it out, and ram her down. You don't put the paper in the gun, they aren't combustable of course, but you just stick the discarded paper in a back pocket so as not to litter...only takes an extra micro-second to do that.
It's a very fast system especially if you have an in-line capper. You can make them while watching the Outlaw Josey Wales or something on T.V....so there is really zero-time involved.
Oh yeah if you use wonder wads, you just poke one down on the ball, after you seat the ball in the bottom of the tube/cartridge paper, and before you pour in the powder.
It's fast and easy revolver loading, been using them for many years. Try it you'll like it.
