I just came back from the range. Shot my Encore .50 with 245 grain power belts. I used Pyrodex pellets and 777 pellets. Two pellets each, don't believe three will all be burned up or make much difference. Either way, I had almost the same point of impact with the 777 as the Pyrodex. The difference was negligible, maybe an inch at 100 yards. The 777 pellets looked a little smaller than the Pyrodex and they didn't have that heavy sulfer smell in the smoke. I am sure the 777 is less corrosive on the barrel. Some say the 777 is much cleaner in the barrel, however, based on my between shot patches, I would say 777 is only about 25% cleaner than the Pyrodex. I am going to give the 777 a whirl this season, after four years of Pyrodex.
