I am reading Fox Fire 5, as it denotes the 5th in the series old time Appalachian folk ways. On pages 246-248 there is a recepiet for home made Black Powder. In fact most of it's 500 or so pages is devoted to Old Time manufacturing of Flintlocks, Iron Making, Blacksmithing, Making flints and so on. A good book to have.

Also I was reading Eric Sloane's book of Do's and Dont's of yesteryear, A treasury of Early American Folk Wisdoms, and on page 48 is a simple recepeit for making gun powder.

Now you will have to get copy's. This is for information only. Don't wan't Ol'Shotgun mad at me cause some side stepped the 2nd Amendment by using the first.
