People are stocking silver now in droves because they need it for the coming post-apocalypse melt down. Only silver can defend you against the waking Vampires of that time, and there will be more vamps than silver bullets.
I thought it was the werewolves your silver bullets will vanquish. I would expect a major run at Home Depot for stake wood, however...........
Hmm, might have to melt some down for silver teeth. Then all you'd have to do is smile at them. Although vampires can't come in unless you invite them, so I'd just stay home anyway.
I put my faith in God, AK-47, and plenty of long lasting sure fire Wolf ammo. A quality sword and knife are also handy.
An army of kids with .22's would be an asset. For rifles, I would go hollow point on the undead and FMJ for all else. To be prepared, I would alternate the types of rounds in the magazine.
