I started with brass, circa 1962, fit the style of what I made.
Some dozen guns later I made one in wood, on order.
Dunno which was easiest.
Make what you like.
Oh, yeah - I am an Old Geezer and used an actual Ink-on-Paper Book by William Buchele, Toledo, Ohio as my teacher. Get a copy of Recreating the American Longrifle, current edition is by Buchele, Shumway and Alexander. Then buy your CNC machine later, once you've learned to do it the simple way.
