Not saying it would be my choice for carry, but are you trying to factually state a hollow point bullet from a .22 WMR will not kill you?
No. I'm saying that the penetration from a .22 WMR hollowpoint is not up to standard, and may not cause an incapacitating wound if you use it.
Your better bet is solid nose in that caliber, if you have to carry it (which I wouldn't).
