Makes me feel pretty smart(sort of)that I spent the last two weeks constructing the paper tubes for .36 and .44. Not quite done yet until I have a nice big pile for both. Loading the powder later is the easy part as I don't personally load any projectile as I don't know which round ball or conical I'll be using that day. Also, so many of the reproduction pistols won't take an entire paper cartridge length without modification. I mostly use the paper cartridges at Cowboy Shoots as they make the loading process quicker and easier. But geez Mike, I couldn't believe the price either.
Hawg, you ask who would buy them? Muzzleloader magazine had articles recently where the author purchased paper cartridges in both 36 and 44 to test in percussion pistols. Said he was going to buy more. I don't understand this as the gentleman is a very experienced black powder shooter and recognized author and I'm sure he would know how to make these things.
