I am thinking about building a blackpowder that is smokeless capable. I am going to use a #1 action. I was thinking about using a standard size .473 cartridge with a large rifle primer as ignition and having the extractor on the #1 to kick them out. I figure I could make a nipple the shape to match the inside of the case head and cut the cases off around .500 long. If I just cut a flash hole the same as in the case and cut as much away inside the breech plug as possible to allow the blackpowder to get as close to the primer as possible........ Ideas? Do you guys know of a good peep site setup that I can use on the #1? I am in colorado so I can't use sabot's or scope.
