50 caliber BALL loads show the tremendous difference in barrel length and twist. My TC ThunderHawk thru chronograph. Never use FFFg powder in a rifle unless the manufacturer specifies it. Balls cannot compete with conicals and saboted conicals in speed and energy in today's high twist, short barrels. They simply are not heavy enough to allow large powder loads to burn completely in the barrel.
Balls require a long, low twist barrel.
The balls in the above chart are all the same size and weight. My TC ThunderHawk thru chronograph. Suggested loading data from back of Lyman 335 grain hollowpoint sabot package. Never use FFFg powder in a rifle unless the manufacturer specifies it. The 180g ball loads show the immense difference that powders, barrel length and twist make.
