There is no "formula" that will predict bullet performance -- kenetic
energy, while scientifically sound (derived by Newton, from his laws of
motion) doesn't tell us how the bullet will perform.

As an example, a .223 (5.56X45 NATO) round has more kenetic energy than
a heavy .45 Colt load.  Yet the .45 Colt would be a more reliable
"stopper" in a fight.
