I have been shooting these things for about 45 years and have tried every different brand that came my way during this time. These include DuPont, GOEX, Curtis & Harvey, Elephant, Schuetzen, Swiss, and probably a couple more. My all-time favorite was the Green River black powder made by Western Technology, Roosevelt, Utah, back during the 1970's. Wonderful stuff....clean, consistant, and hot. Their powder works blew up , with the loss of several lives, and was never rebuilt. I still have a couple of unopened pound cans of it. The closest thing I've used since has been the Swiss.
