Good suggestion, Bindi2. A 730 @ 2,500fps, by the formula, produces 10,133fpe - so that number and designation actually means that bullet developes the energy required to move 10,133 pounds, 1 foot.
I don't happen to believe that it will do that. You shouldn't either. It is a meaningless number in relation to a bullet. The formula is flawed and should not be used to describe anything to do with bullets.
This post is not meant to belittle the potential killing power of a 730gr. bullet at 2,500fps, just that the formula does not produce meaningful numbers to explain or express that power.
