This exit in the rib cage of a bulle Elk is from a 440 grain flast point hard cast from a 500 JRH at 960 FPS for only 888 FPE
Energy figures on a piece of paper mean exactly dick
I wouldn't exactly say they mean dick. In fact the energy is the basis of many other equations to predict terminal ballistics. The energy tells you how much energy will need to be expended to stop the bullets travel, simple as that. The "energy expended" to stop the bullet first comes from the air then the ripping apart of the flesh of your prey and if the bullet goes completely through the animal then its comes from air again.
The caliber, mass, bullet type, etc clearly also each play a factor. I just haven't calculated some of the others (like TKO) for this .45-90 hot load yet.
