I caught this little news article about Zombie Bullets being marketed and with the recent hoard of flesh eating stories popping up it's probably not a bad idea.

"Yes, zombie bullets. Ammo maker Hornady has cleverly marketed a set of its bullets as "specifically designed to vaporize zombie varmints." Company owner Steve Hornady absolutely loves the horror genre and thought the gimmick might help sell product.
“After it gained some acceptance among [people], some of us here in the company got on board with the idea and we decided just to have some fun with a marketing plan that would allow us to create some ammunition designed for that … fictional world,” company spokesman Everett Deger told CBS Detroit."
