Zombies. It's for zombies.

Zombie Rinos maybe. Around my corner of the interwebz we judge 22mag to be the premo zombie stopper. Only head shots count and you need to pack a lot of rounds, so 22 mag is the blessed cartridge. Many choose 22lr, but I give the human head more credit in the toughness dept. Muzzle report is a factor too, as well as action noise...we came up with a lever action 22mag with a muffler and spike bayonette as the best tool for zeds.
4 lulz.

I did a fantasy short story once where a necromancer brought horses back from the dead with carnivorous tendencies.

Their bites were horrifying.

What about the Zeds from "Monster Island?" If they kept feeding they'd get huge. Or the Zeds in riot gear? Don't forget the "LAMOES" (Last Man On Earth Syndrome) from WWZ. Just in case I'd pack something a little more substantial. 5.56 seems like a good round for the zombie apocalypse. (though I'd have a hard time finding a gun in 5.56 that I'd take during the zombie end of the world.)

They make a Saiga .223/5.56, don't they?

Good call, indeed they do, but don't those have problems with the mags? Anyone got any experience with them? I'd love a Sig .223, but I was thinking about guns I could afford. Same thing for an HK 416, love it, but could never get one. For some reason, .223 is the round of the AR and that would be the last weapon I'd choose for any end of the world scenario. Loose one little pin and you're screwed royally. One of these air guns would be pretty sweet though if you're just dealing with zeds.

Well, in MHI Zeds are also delt with effectively with large bladed weapons. They can't grab you if hey have no arms... they can't bite you if they have no mandible.

My anti Zed kit is my AK, Native American gunstock club. It's from Cold Steel and can bash and the spike gives it skull punching power. I don't know why it's a Japanese chick holding an Indian weapon, but I aint complaining.
