If you have any doubt that we live in the best of all possible worlds, take a look at this. The five (yes, five) shots in the single hole in the bull were put there during the NBRSA Nationals in St. Louis. They were fired by a contractor from California named Tom Libby, and his rifle of choice was a 6 PPC. The group measures .093-inch, and the big sockdolaper is, it was shot at 200 yards.
I am indebted to Mr. M. Coleman, gunsmith, raconteur, and philosopher, for the photo and the info.
