 Yeah again, Dunn starts groaning and moving and bang another bullet to the head. I mean really guns have more than one bullet why would he suddenly stop doing the only thing proven to put Dunn out. I'm sorry for being snarky but it seemed like a very very VERY obvious solution to me. If you knock a guy out and he starts to wake up and you want to knock him out again then you just hit him. I mean how could you not immediately assume that. Also I did say this: Which I admit isn't terribly clear but it does strongly suggest that I had acknowledged the fact Dunn would wake up relatively soon after the shot to the head and that more would be required to keep him in that state. Edit: Eventually yes. Right away not so certain. McClain relies on bullets far more than fists. Fists are a fall back for when he doesn't have bullets. Which is why for me this is still a toss up. One or the other would have to get a fairly lucky break to become the winner. And Dunn has his own gun, and his own training in using it. So in a gunfight between Dunn and McClain, the guy who is bulletproof would win.
