I know, I was just being silly.
Fair enough, on the internet you never can tell if someone's being silly or just stupid.
I was just arguing semantics really. If you came across a machine gun with .50 calibre bullets and had plenty of them then this principle of mounting at a higher height to get a better "chance" of getting a headshot will increase the average amount of bullets that hit the head because you move the bullet to air density up the body. Any kind of LMG puts off rounds that punch through bodies so if fruitful circumstances arise then this could be a better application then simply walking around with it.
I'd probably save it for home defense (And probably use it against human attackers more than zombies)- if I find a machine gun, I'm likely to find several assault rifles and pistols nearby, which would be more useful for zombies.
I would think dead people smell horrible, were not exactly grain fed beef! (unless your a vegetarian, then your just good eats)
Generally zombies don't tend to rot, or if they do it's at a lot slower rate than normal corpses. So at worst you're likely to be burning meat that's only slightly rotten. The difference in smell to fresh meat would be very little, I think. And I know several blacksmiths with first hand experience who tell me human flesh smells like bacon when it cooks.
