This paper cartridge forming kit is for the 12 gauge shotgun pistol known as the Diablo/Desperado. These are 209 primer guns, and the kit is as yet untested in standard percussion shotguns. 

The long pin is matched to the size of a TrueWave jumbo hair end wrap. This is used for the body of the paper cartridge.  The end of the cartridge utilizes standard cigarette rolling papers. We supply Elements brand rice papers with our kit, but any rolling paper should work fine.  We suggest a 1" circle cutter, which is available at Michaels. 

Cut the paper shorter for cartridges that do not have a long wad, then flush up the bottom of the paper with the bottom of the pin when you glue it.  Any size cartridge can be formed this way, with any combination of powder volume, wad and projectile. 

The dipper included in this kit is 100 grains. This far exceeds the manufacturer's recommendations for this gun, so you should develop a load that works for you, starting small and working up.
