I think we all know this is not a man stopper round. Nobody, including the OP disagrees with that.
Still, Christopher McCandless took down a moose with it, and suffered no damage from the moose.
Point being, if I were unarmed and attack seemed imminent, and one were to throw me a firearm chambered in .22LR, I'd hardly throw it back at him.
(Unless I were looking to inflict as much damage as possible with it, right?)
