There is a reason that the skull is sometimes referred to as the cranial vault. More than a few .22lr have bounced off a skull, or skittered around it under the skin.
Thanks, but I'll use a real caliber. There is a reason that police agencies use 9 mm and up.
more than a few .22's have also pierced the skull, and bounced around inside a bit. or cut arteries, or torn aortas.
.22's killed alot of nazis during WWII while being used by the resistance.
