Why not make your own? If I can do it while living in my tenth decade....you younguns surely can too. I make my own charcoal and then my sporting grade black powder. Of course, I use a ball mill with a rubber jar and lead balls for grinding`. Make quarter pound batches for safety's sake. I work outside on my deck and keep my work area very clean from loose powder and the like. I have used, with good results, charcoal from Eastern red cedar, mesquite, mimosa, and grapevine and do not coat with graphite. My cost is about $6 per pound give or take a few cents. Loads of information on Youtube from expert powder makers. Merry Christmas to you and yours and keep your powder dry....whatever it is!
