".….Didn't that Muslim yelling alah akbar at fort hood kill dead a bunch of people with a piss ant FN 5.7?."
You just made the argument we are all talking about. FN shooting 40gr VMax around 1800 fps. Does a lot more damage than a 22LR shooting 40gr HP at 1200 fps.
And well below 2000 fps. Velocity matters, even under 2K fps.
