Is there any hard evidence? Why don't people CC them then? How come when butchers kill cattle they use a bolt gun that shoots out a spike powered by a blank instead of a live 22?

Edit: I found a medical book called Traumatic Brain Injury by Granacher. Not linking to google docs. It says 22 can penetrate and bounce around in the skull like the old stories says. But it also says many people survive suicide attempts with 22 (and 25/32) but seems to be because the put the gun in the wrong place. Mortality rate is 25% for anteroposterior vs 83% for lateral according to the text.

Maybe ear could work but eye would be better. Or underneath the chin past the mandible.

I was listening to an old podcast about terminal injuries interviewing a trama doctor in Chicago I think? Some gangbanger shithole city. Anyway it had all kinds of weird outcomes. Like a 22lr went under a guy's skin and traveled from his torso up to his neck (killing him) but a girl got shot point blank in the head with a 45 and it bounced off her skull. The only thing I learned for certain was the niggers always use the cheapest fjm they can find. I can't remember the name of podcast though.
