This is the exit in the off side rib cage of a 6X7 bull Elk from a 180 grain fired from a 300 win mag the impact energy was aproximately 2700 FPE. I am holding a loaded 300 win cartridge for size comparison
The is the exit in the same Bull Elk from a 500 JRH shooting a 440 grain wide meplat hard cast at about 950 FPS for a muzzle energy of 888 FPE
Again I am holding a loaded 300 win mag round for size comparison
The larger wound was caused by a round with about 1/3 of the amount of energy of the 300 win
Energy is a very poor indicator of lethality
