A lot of talk when comparing calibers often revolves around bullet energy. While some argue that you need a larger round to be effective, in terms of energy, velocity counts exponentially more than mass. The formula:
E=1/2(mv^2) Shows the relationship between mass and velocity. You can see that a gain in velocity will produce a much larger gain in energy than a proportionately larger round.
For example, a 230 Grain .45 ACP traveling at 900 fps has 414 ft/lbs of energy. While a 146 Grain 9mm traveling at 1210 fps has 474 ft/lbs of energy.
If you really want a round that produces a large amount of energy, a 200 Grain 10mm traveling at 1300 fps, has 750 ft/lbs of energy.

If ye love wealth better than liberty, the tranquility of servitude than the animated contest of freedom — go home from us in peace. We ask not your counsels or arms. Crouch down and lick the hands which feed you. May your chains sit lightly upon you, and may posterity forget that you were our countrymen!
