When I got into handguns back in the mid eighties, my mentor was a retired gentleman who had been a long time bullseye competitor. In the Fifties and Sixties he shot in several bullseye leagues that were active here in Vermont at the time. He said that in one of the leagues, the Border Patrol agents from the station on the Canadian border would come and compete. At one point, Harlon Carter was stationed there for a while. My friend said that one time they asked Carter whether Elmer Keith really made the shots he wrote about. Carter's reply- "When you go through life shooting at everything in sight, you're bound to hit something now and then."
