You cannot use modern anything to build a traditional muzzle loader. You must be an apprentice for a very long time and learn how to do everything the old ways. Once you have helped build several hundred arms your master gunsmith teacher will help you set up a shop of your own. That isn't happening. I will use everything and anything, be it a wire welder, milling machine, superglue, epoxy compounds, and the like to build my guns and cannons. They will look, shoot and last just as long as any built without the use modern equipage. Sometimes better and longer.
