Cooper’s Load
In his book, To Ride, Shoot Straight, and Speak the Truth, Cooper stated, “All scouts up to now have been in caliber .308, and the chronograph insists that the proper loading can start a 150-grain bullet from a 19 inch barrel at a couple clicks over 2700 f/s. These ballistics served Theodore Roosevelt and Steward Edward White very well in Africa, and they still can.”
