theres this book, movie soon, i havent read it but my friend loves it, that describes in detail the logistics of shooting up zombies.
most likely, it wont work. does anybody know the actual ammount of ammunition produced? theres then the matter of shooting moving targets, crisis moments, where tooons of covering fire may be wasted, especially if the zombies figure out to use guns, who knows
remember, even the nazis figured out they couldnt use simple bullets to kill the jews of the world, which at the time counted a few tens of millions.
youve seen the movies also, in any little small band of survivors, some jackass is gonna get himself scratched, and soon transform. we'd be doomed
