I've never used them for revolvers but had great success with my .54 rifle. The hard part is finding just the right diameter forming dowel. I had to turn one down a bit. I use printer paper and cut it so it makes two layers without any overlap. I water down some elmer's and glue the edge with a small paintbrush. The ball should fit into the end of the tube skin tight. Then I tie off the ball and load a wonder wad behind it, then the powder, then glue the end flap to the side. Then I tie some thread behind the wonder wad so that it makes a slight groove to hold some lube and also keep the ball from liding down the tube when loading. I use chapstick for lube since it's thick enough not to smear off in your pocket or pouch. When loading, tear open the powder end enough so that the powder will pour down the bore when the tube is placed in the muzzle. Push the whole thing down your barrel and you're reloaded. Works great for fast follow-up shots and is surprisingly accurate.
I think a tapered forming dowel would work even better but I haven't tried it yet. Bill
