Hi I am new to the forum. I would like to eventually build a large bore Gatling. I saw parts of what I think was a poor condition 1 inch gatling at a civil war show several years ago (could have been a hotchkiss) and I cant get it out of my mind. I am thinking about a 12 gauge (with BATF approval on a form 1) with counterbored barrels to get the 1 inch look. Or I could do a 50-70 with counterbored barrels. I am a long way from starting as I am without machine tools right now but they are coming in the near future.. I know this sounds ambitious so it may turn into an RG-G 22cal but you have to dream big. Lol
