This recipe on one charge had come from a friend of mine who had issued it with the help of a handladdnings programs. How about that?
Cartridge : .416 Rem. Mag.
Bullet : .416, 350, Barnes 'TSX' 41686
Cartridge O.A.L. L6 : 3.600 inch or 91.44 mm
Barrel Length : 24.0 inch or 609.6 mm
Powder : Norma 203B
Predicted data by increasing and decreasing the given charge,
incremented in steps of 2,0% of nominal charge.
CAUTION: Figures exceed maximum and minimum recommended loads !
