Muzzle energy is the result of bullet mass (grains) multiplied by velocity. Or if you want to get technical kinetic energy which is 1/2(mass*velocity)squared.
.40S&W Federal Hydra-Shok 180gr.JHP 950fps 361 ft.lbs. Big slow bullet, less energy
.40S&W Rem.Golden Saber 165gr.JHP 1150fps 485 ft.lbs. Light fast bullet, more energy
