Washington Post reporter surprised to discover some guns more dangerous than others

For the better part of the last six centuries, from the first matchlock to the latest machine gun, gunsmiths have been trying to perfect the lethality of firearms. Somehow this is still news to the Washington Post.

A recent story in that paper cites new research which found a direct correlation between caliber size and shooting lethality. The bigger the bullet a gun fires, those researchers discovered, the more damage it will do to another human being. That’s enough for writer Christopher Ingraham to conclude that “not all guns are created equal.” But that is obvious, not groundbreaking.
