We aren’t talking distance shooting. We’re talking close quarters ambush. Both are quite deadly. Yes, the AR will make more of a mess. The Virginia Tech shooter killed over twice as many people with 9mm pistols. There’s no such thing as killing someone twice as dead - dead is dead. And if you are going to the milk jug test a shotgun with slugs does more damage, much more, than an AR or a Pistol. But all three kill that milk jug dead.
No, we were talking about the effects of a rifle round vs a pistol round. I dont know why you want to argue.
As much as I like Clint Eastwood, Ramone was right:
When the man with a 45. meets the man with a Winchester, the man with a pistol is a dead man.
