Yah, you can come crying to me when your face gets eaten off because you had to make a choice between a rifle and shotgun (carrying both, plus ammo, is quite a burden, and absolutely slows down your ability to escape and move undetected), and you chose the shotgun, and your place of refuge was quickly surrounded by hordes of the undead because one of them got inside and you unloaded both scattershot barrels in his head and alerted all the other zombies in the area, and were unable to pick them off from a safe location because, as I noted earlier, after about 10 feet, shotgun pellets are nothing but a minor annoyance to the undead, and by the time you were surrounded, it didn't matter how many scattershot rounds you had, because they kept on coming.
