Who really cares which cartridge beats out another by a few fps or foot pounds. The fact of the matter is, and the purpose of the thread, we are all overgunned when it comes to hunting whitetail deer.

If we were to use the same energy per pound of animal that the 270 generates on a 200 pound deer to hunt cape buffalo we would need to use a cartridge capeable of propelling a 1000 grain bullet at about 2600 fps generating 15000 foot pounds of energy.



Or how about a 160 grain 7mm STW on a 110 pound antelope?
That's 2670 foot pounds of energy at 200 yards as loaded by Federal.
That comes out to 1.46 grains per pound and 24.27 foot pounds per pound of animal.

Take those numbers and use them on a 1500 pound animal.
That's a 2190 grain bullet at 2740 fps. generating 36,405 foot pounds at impact.

Anyone care to build a rifle that will equal the on game performance of the "deer cartridges" on larger game like buffalo, elephants, rhinos, etc.?????
