I notice they didn’t have a line for the 22 mag. That friend of mine has told me he shot it through a 4 inch phone book. Better penetration than .38 or 9 in fmj. Of course it’s not doing the same damage going through, but I was impressed enough to stop laughing at the little thing.
As I understand it the 22 will kill you through blood loss. Not through shock or major organ damage. That translates to the attacker having time to fire back.
