Very cool. I know little to nothing other than the modern muzzle loader I have for extending gun season. I decided I would rather just hunt with a bow through muzzle load season since I had better accuracy with it than the POS muzzle loader I bought. Like anything else you should never scrimp on things that matter.
I just think it is a very cool project. The people who have the skills to do things like this are the ones who survive when the fesces hits the windmill.
