That's O'Connor, not O'Conner. Yah you're right, Jack did shoot game with a 30/06. He also used a 375, 7mm Rem Mag, 338 Mag, 22/250, 30/40 Krag, 7mm Wby mag, 300 Wby, etc., etc. He was a gun editor for a national outdoors magazine. If he only used a 270 all the time you'd be complaining that he couldn't possibly know if any other calibers were good. "Waxing poetic" about the 270? Nope, he was just telling it the way it is. Try one, you'll like it.
