Yeah, the walmart people dont know anything.I asked one guy if they had any s&w500 in stock.He said, "Whoa,you have a 50 cal? Thats huge! But sorry,we dont have any ammo for assault weapons.......just normal guns." What a bloomin idiot. And he was standing right infront of several boxes of 223rem, and 7.62x39mm. A 5 shot assault weapon huh?
