I remember he recommended sighting in 3 inches high at 100 yards to maximize point blank range. I did for years until I realized 100 was about the maximum range I could shoot.
I first embraced that same piece of JOC's advice circa 1967 and continue to use it for the majority of my deer hunting rifle 50 years later. Despite the improvements in technology that we've seen since JOC shared the bit of advice, it has stood the test of time and is as valid today and it was when he first offered it for the vast majority of the average North American deer hunters.
