About this powder

Trail Boss was engineered from the ground up for cowboy action shooting — reduced-velocity, lead-bullet loads in large pistol and rifle cartridges. Its unique donut-shaped flakes fill the case so completely that a double charge is physically impossible in most applications, making it exceptionally safe for competition use. Perfect for .38 Spl, .44-40, .45 Colt, and lever-rifle loads.
