I have most of the hardcover books that O'Connor wrote, and used to lap up his magazine articles with gusto. I feel he was one of the best...called a spade a spade. Not too tolerant of egotistical people who thought they knew when, in fact, they did not. His 270 articles never pushed me to buy one, though, and I never owned a 270 till about 15 years ago, after Jack was gone. I feel it is a good chambering, but does not have any magical properties, just a Jack stated. His wife, Eleanor, took a lot of game with the 7x57 and the 30-06, the latter even accounting for a Lion in Africa. I miss writers like Jack. The current crop falls short, for the most part. Regards, Eagleye.
