I built a .45 cal black powder pistol from a kit about 35 years ago. It is a Patriot .45. Was an interesting experience. I was into the 1830 era Mountain Men experience. I also made a Thompson .45 cal Hawkins rifle (which I still have). I kept the same caliber for both so I wouldn't have to worry about different balls. Here is a photo of the Patriot. http://sports.webshots.com/photo/2125339190104782481Yjvixy Wanna kill these ads? We can help!
