Myself and my buddies grew up with Jack O'Connor, reading every book and article we could lay our hands on. I suspect that he could have been much closer to one of us LR hunters then we might think….. were he exposed to the same progress and evolution of the technology. In his day, his was somewhat of a black sheep, adopting his favorite 270 Winchester cartridge using 130gr bullets at the highest velocity he could squeeze out of it. His articles frequently justified/promoted his use of high velocity/smaller projectiles to the larger caliber/lower velocity, traditionalist crowd. He was well practiced and prepared for the 300 yard shot which back then was considered far for a high certainty shot considering firearm/optics technology, bullet design, and the lack of precise ranging/atmospherics equipment. Who's to say that 300 yards back then(60's) isn't the equivalent of 700 yards today. Skill was(is) required in either case. Having also been a bow hunter and muzzleloader hunter, I don't buy the stalking skill dramatization. You choose and adapt how you deploy your skills be it shooting, stalking, or both. I stalk close enough to take a skilled and confident shot with the equipment I'm using, and use a similar strategy for choosing a stand/hide. We never know for sure, but it's quite possible Jack O'Connor did the same in his day. He was a "Rifleman".
' IMO.
