How's that for a hole in the head? Saw this story in the New York Times which speculates a discovery may be the very first known gunshot victim in this hemisphere. Guess you could call this the first “whodunit” on this half of the globe. http://www.nytimes.com/2007/06/20/science/20inca.html “Less than an inch in diameter” is not exactly an accurate measurement, but just looking at that big ol’ hole in the Inca skull leads me to guess it was closer to an inch than a half-inch, which means the musket ball was larger than .50 caliber, maybe closer to .75 caliber. They musta had some serious size Spanish muskets back in those days. I guess what they lacked in accuracy they made up in “stopping power.” A slug that big is a serious “stopper.” I googled Spanish muskets of the 1500's and found references to a "12 bore" which is equivalent to 12 gauge and also to .75 caliber, which would be 3/4" diameter. It also said these early musket balls were "10 to the pound" so the hunk of lead weighed 1.6 ounces. That's a 699.999-grain hunk of lead. A serious "stopper."
