I haven't read all of this, but I remember an article by Robert Robel where he had a formula for calculating killing power for large game animals. He called it Momentum Value and the formula is bullet weight in grains X speed in hundreds of feet per second.

His examples:
250 grain bullet at 2600 fps at the muzzle = 65 MV at 300 yards = 52 MV
130 grain bullet at 3140 fps at the muzzle = 41 MV at 300 yards = 20 MV
175 grain bullet at 2860 fps at the muzzle = 50 MV at 300 yards = 37 MV

Probably way too simple to be of any value, but easy enough to figure and make some comparisons.
