Continuing our discussion of good guns for the undead . . .
9. Lever-action rifle in .357 magnum or .45 Colt – Just like the last few minutes of the theatrical release version of Army of Darkness, you too can go after the undead with a modern replica of the frontier classic. Check out Cimarron Arms in Fredericksburg, TX for a great selection of extremely well-made western-style leverguns. Some of the longer barreled models even hold up to and include 10 rounds, which should put a significant dent in a squad of undead baddies. The benefit of a lever-action rifle is that you can shoot and cock the weapon without taking your eyes off the target, the guns are generally light and carry well, they have an unobtrusive look that makes you look less dangerous to the shell-shocked humans you would encounter on your scavenger journeys across the Wastelands.
Why not the .44 Magnum? Overkill . . . both on the zombie and your shoulder.
10. Pump action riot shotgun – Ah, we all love the classics. The pump-action shotgun – ubiquitous weapon of urban self-defense – is also a good choice for the undead. It provides a mess of firepower in a easy-to-use, easy-to-carry package. With a ‘00’-buck load, you also have the added benefit of taking out both the zombie you are aiming at, and the one next to him. Detractions include limited ammunition capacity (even with higher-capacity weapons you can still only hold so many rounds in your kit) and a hard kick (worse for new or younger shooters).
The good news is the scroungability of the 12 gauge shell. It’s so common you’d likely even find a few boxes of shells hidden away in the closet of even the most ardent gun control supporter.
