Okay. Is there ANY muzzle velocity out of ANY barrel length AR that would break up in someone’s skull at 10 feet?
And what would that be?
Because if he doesn’t have it, it didn’t do it.
It isn’t so much the velocity that is critical, it is the projectile construction. There are .223 /5.56 rounds that won’t fragment when they hit armor. There are others that will about turn into dust if they hit an apple.
Dude. Stop.
This is a criminal case and you are posting in a public forum.
If you won’t stop, please freepmail me your name and State of practice so I can avoid you like the plague.
