Swine Flu

[Hoofhurr]

See it's my opinion that a shotgun does more to increase infection rates than to increase personal safety in the event of a zombie epidemic due to the obvious increase in splatter-radius of blood and brain matter. It's really a surefire way to infect your loved one's who have been cornered in their bedrooms by a raving mad zombie. A rogue, errant fleck of blood in little Timmy's eye and blammo you're the star actor in your own personal familicide horror movie.

It's a medium caliber round to brain stem, spine, or kneecaps imo.
