I'll chime in here, and I'm certainly no expert. I made a bunch of paper cartridges for my .36 navy, and tried the raw papers, made my own nitrated paper from coffee filters, used hair curling paper, and even bought flash paper. The first thing I learned was the Raw papers was very thin and difficult to deal with. Nitrated coffee filter paper was much easier to roll, but did not burn completely. Flash paper is OK, but very expensive and still did not burn completely. Hair curling paper seems to be a good compromise, easy to use and does not leave Too much unburnt paper behind.
The second thing I learned was that I had a really hard time trying to stuff a conical bullet on top of a powder charge in the cylinder. They have to be "bent" to get them to go in straight, and sometimes the paper breaks, and sometime the bullets goes in a little crooked, and if you try and push in on in with the rammer, as often as not it does not go all the way down and you end up having to remove the cylinder to get it back out.
I found out its easier to make little powder cylinders, like Outlaw Kid does, then you can use ball or conical. I like prelubed felt wads, so I put a powder charge in, put the felt wad on top of that, then a ball or conical, and it all seems to work well.
I fish the unburnt paper out of the cylinder after each load using a long qtip qith a wood handle, but its not an issue. I realize it isn't be the fastest way to reload, and if I had a war party of screaming Commaches after me it might make a difference, but I don't shoot BP revolvers to see how fast I can burn through powder, I can use other guns for that. Just my $0.02 worth.
