Which load is better?
I have a .38 Special for which I have 2 bullet choices: a 158gr LSWC and a 125gr JHP. Both are equally accurate.
The 158gr velocity is 836 fps, which delivers 245 ft-lb of muzzle energy.
The 125gr velocity is 895 fps, which delivers 222 ft-lb of muzzle energy.
Since the accuracy is equal and the difference in energy is not impressive, how does one predict which one delivers a more efficient terminal defensive effect at the same target distance?
