I have had a jug of pulldown powder (8208) for quite some time and am seeking some information as to its burning rate. I know it is a long shot, but I hate to see it go to waste. It came from the estate of the late Raymond Brunet and I believe that he shot it in a 6 PPC. Any help would be very appreciated. I am thinking of using it with a 6 BR with 68 grain bullets. James
