This revelation comes from Scott Bowen, a former editor at Field & Stream and author of the new "Vampire Survival Guide" by Skyhorse Press. (It's no surprise to me that Bowen wrote this book. Scott is very pale and seriously, I never saw him wear anything but all black. But, I think he's on our side). The "Vampire Survival Guide" is an entertaining read, along the lines of "Zombie Survival Guide" but funnier and more thoroughly imagined. As you might expect, given Scott's F&S background, there's a section on guns and loads. In it, he explains that vampires are no different from anything else. They will succumb to "massive tissue damage" even if that tissue is already undead.
