You all continue to confuse the absolute realtionship and 100% correlation between energy and penetration when discussing solid bullets and everything else.

Recall, two identicle bullets fired at two velocities; the faster will penetrate deeper. (and so cause greater damage as well, by means of a longer - and likely wider too - wound channel)

Discussing Taylor's tables, he uses momentum rather than energy to come up with his KO values. Momentum relies on velocity rather than velocity squared and so emphasises bullet weight in his formula, which it ought to. But use his formula and two identical bullets at two different speeds and - guess what? - you will come up with two different KO values, the greater of which reflects the greater velocity.

Velocity is a critical element of the mathematical calculation of energy. Ignoring velocity, and so energy, is ignoring a huge factor in penetration and capability of any solid bullet. Leads to dumb ass arguements along the lines of 45-70 = 458wm = 458 Lott = 460Wby. Nothing could be farther from the truth. But for best results, follow the Brit lead of 110 years ago and forego "too much" velocity for bullet weight and keep near the SD = +.305, MV = ~2150fps and move up in bullet diameter, weight and stopping power for given recoil rather than more penetration than is required.
