I'm new to this area but am interested in the study of ballistics.
I recently read where the .50cal BMG cartridge with a bullet weight of 750gr. at 2,700 fps has a ft. lb. energy rating, at the
muzzle of 12,143.
My question is : Why is it that the Federal 10ga. 1.75oz slug at a
slightly larger 766gr. and with a fps at a little less than one half (1,280), rates only at 2,785 ft. lbs. of energy or less than one quarter of the .50BMG. Does 2X the speed equal 4X the impact?
I'd appreciate any clarification. Thanks.
Mike
