While you are right about the physics of the guns and how shotguns should probably do a hell of alot more damage, from a gameplay perspective I feel I should point this out: The M1014 benefits from having some of the most ridiculously common ammunition in the game. 12 gauge shells can be found in virtually any building in the game; the milspec ammo cannot. That is a fairly dramatic advantage in my experience so far. But yes, I'd like to see the shotguns actually do more damage... alot more damage at that. But I am biased; I always carry M1014's if I can possibly help it, because let's face it, what's a zombie apocalypse without a shotgun?
