The 5.56 NATO round is faster than any of these 22 caliber handgun rounds and it isn't a good shot stopper either. Fact is a determined attacker can continue to press an attack after his internal organs are destroyed for a period of time.
The only way to always effect an instant 1 shot stop is to take out the central nervous system.
It is as simple as that.
Damn, beat me to it, so according to the OP a 22 cal rifle is inadequate for a SHTF rifle, but a 22 cal pistol going at least 1,000 fps slower is a one shot killing machine on men?
Wow
