RE: Who Has Used Pinnacle Powder?
It depends on the rifle and what I am shooting. In my Wolverine LK-II I used to shoot 80 grains of Pinnacle 3f powder and a 240 grain XTP with good accuracy. When I shot roundball I used 90 grains of powder and the roundball.
It did not shoot conicals real well, but it is very clean, had good power, and I kind of liked it. Although some of my rifles hated the stuff.. I works real good in black powder revolvers by the way.
