Shot placement does not end with piercing the skin. Shot placement is three dimensional, and penetration is a must. Sure, you have to get the round in a vital area, but if it doesn't go deep enough you will not win. Ironically, a .22 to the brain or high spinal cord is often just as effective as a .44 magnum in stopping the encounter.
Many people look at gel tests and see that their self defense choice will penetrate 12 inches and for some reason that defies logic, they are happy with that. According to the FBI, twelve inches is the absolute minimum
acceptable penetration in gel testing, and the round must do it consistently before it is deemed even marginally acceptable.
When we choose a self defense round should we consider the barrier testing done by the FBI? That's a tough one. If you live in an area where road rage is common you might want to take a long look at windshield penetration testing. The law does consider a car a deadly weapon, and if someone is trying to run you down deadly force may be a necessary option. You know where you drive, you know how you drive, and you know how frequently you manage to tick off other drivers. Choose accordingly.
