There are a lot of Sources that report that Shotguns are THE BEST anti-zombie weapons. There is no reason to doubt the effectiveness of the shotguns in this role. But let's take a further look at the pro's and con's of shotguns as anti-zombie weapons.
Pros:
1.) Nothing says 'I'm a bad a**' more like the sound of a shotgun slide being racked. It's great boost to the moral of any member of your survivor group.
2.) It hits like a truck, and will knock down just about anything.
3.) Ammo is cheap and/or easy to find.
4.) They are easy to use and do not require a lot of skill to hit anything.
5.) It can take blow off legs it's not a kill shot but you can slow them down. At very close range you can almost be 100%sure of a headshot.
6.) Pump shotguns and single shot (double or single barrel) are more reliable than most.
Cons:
1.) Unless you are close to your target the chances of getting a headshot are slim.
2.) The range on a shotgun isn't great for headshot accuracy. Unless you are using specialized ammo then you run into another problem of availability (deer slugs, sabot rounds, ect).
3.) Noise, they make a lot of noise; everyone knows Zombies can be attracted to loud noises, drawing more of them to you.
4.) Limited ammo, you are going to run out. Most shotguns are not quick to reload or have limited ammo capacity.
Shotguns make good Anti-Zombie weapons and in certain situations they could be the best. They might not work well in horde situations, but against small groups it should do fine.
Blowing the legs off Zombies is pretty darn cool, but kill it off quick if you can. Zombies without legs will still chase you, just very slowly. Being low to the ground means there is a less likely chance you see them creeping up on you (stealthy zombies). Getting into or out of a vehicle becomes a risky situation when a hand reaches out to grab you from underneath it.
My Preference for shotgun types: (all are 12 gauge)
1.) Semi-Auto: SPAS-12, Remington 11-87, Beretta 1201, and Benelli M4 are good examples of Semi-Auto shotguns. You can get a good rate of fire
2.) Pump Actions: There are so many to choose from and you can’t go wrong with just about any of them.
3.) Full-Auto: There a few, but most are military only and are hard to get your hands on. I know, I know, lots of firepower! But goes through ammo fast, and additional recoil can really screw with your aim.
4.) Double Barrel: You have to reload too many times, but can be cut down short for a last ditch easy to carry weapon.
Good Hunting!
Some will disagree, but that's ok. It makes for good debate.
