The .223 is not a common hunting round, unless you're talking about varmints and squirrels. While it is legal for deer in many jurisdictions, it isn't a good round, as it has been designed to wound enemies, and cause enemy forces to spend their resources treating wounded, rather than fighting. Deer are about the same size as soldiers, so tend to be wounded by the round, rather than dropped in their tracks.

It's hard to say the same about the .30-06.

Folks that have never been under fire, have never had to disarm someone threatening them with a firearm, and have never calculated a ballistics table, are poor sources of advice regarding what works, and what doesn't in such situations.

Also, the first threat to the shooter was an unarmed man. He did the right thing, which was to attempt to engage the shooter point blank, where his firearms couldn't provide much advantage.

IIRC, that was when the shooting stopped. I could be wrong. However, if he'd been armed, he could have stopped the shooting for certain then.

The balance of your remarks are right on.
