Who is the most famous hunter in America? If you’re over 30, the first names that come to mind are probably Sarah Palin, Ted Nugent or Dick Cheney. If you’re under 30, the answer is easier. The most famous hunter in America is Mark Zuckerberg, the billionaire founder of Facebook.

In May 2011 Mr. Zuckerberg made a pledge to consume, for one year, only meat he had hunted or slaughtered himself. He got a hunting license and shot a bison. “My personal challenge,” he explained, is “being thankful for the food I have to eat.”

If four new books are any indication, Mr. Zuckerberg is the decidedly nonmacho, non-pickup-driving embodiment of a new breed of American hunter. These young memoirists have loaded their rifles and shotguns for complicated reasons, including culinary one-upmanship. Nothing wows jaded dinner guests like a braised shank of calf moose that you’ve recently “harvested” and “dressed” — hunting euphemisms for killed, skinned and disemboweled — before bringing it to the table.
