I don’t believe the attacker was shot with the rifle, unless I missed something when I went to Ammoland. Also, ask Anthony Huber, Joseph Rosenstein about getting center punched by .223.
Nope I missed it and thank you for clarifying.
I remember Petraeus being shot by an M16 and they stitched him up and he walked away fine that same day. Seeing feral dogs shot with a .223/5.56 they always run away. Not so with other comparable cartridges where they drop instantly (5.45/7.62 Soviet).
