I used to nitrate the coffee filters back in the day, but now I like using "Guns of the Old West" cartridge papers. I use "Cap-n-Balls" tools and make my own boxes except the 44 box in the bottom picture I bought from a guy on Etsy. (I can't find them anymore). These all have been surefire, but you must get some of the paper ash out of the chambers before loading. I have shot several cylinders without doing that and it tends to get gobbed off. Both projectiles are the Colt 36 and the Johnston and Dow 44 from guy down south. The Guns of the old west papers are sure fire just like the lower ones which are made from nitrated coffee filters
