Jack O'Connor mentions

From the June/July 2018 FIELD & STREAM magazine section “Cheers & Jeers” letters (Mike Smith, Grangeville, ID):

“I’m now 74 and was raised on Ted Trueblood and Jack O’Connor.
My family didn’t have a lot of money, but we did have magazines and books, and I learned the joy of reading through them.”

From the July/August 2018 RIFLESHOOTER magazine article “Reset To Zero” (Craig Boddington):

“Jack O’Connor, who hunted before there were laser rangefinders or computer ballistic tables, advised hunters to sight in between two and 2.5 inches high at 100 yards and be done with it.
Depending on bullet speed and BC, with reasonably flat shooting cartridges the O’Connor “formula” will put you dead-on between about 200 and 250 yards. Somewhere around 300 yards you’ll have to raise your hold, but you won’t need to worry about holding low in the middle ground.
For most shooting, that’s fine. With a flat-shooting non-magnum cartridge like the .270 Win., I get as close to 2.5 inches high at 100 yards as I can. With the .30-06 it depends on the bullet weight and the purpose, but I never sight in higher than O’Connor suggested.”

From the August 2018 Petersen’s HUNTING magazine column “Guns & Loads” (Joseph Benedikt):

“Jack O’Connor maintained that 7.5 pounds (with scope) was just right for a mountain rifle, and he’s still not wrong.”

From the October 2018 SHOOTING TIMES magazine column “Shooter’s Showcase” (Terry Wieland):

“Jack O’Connor, who made his living from writing about big-game hunting, would, every so often, include a throwaway line like, “It’s all for fun and games anyway...” I doubt he really meant it. In fact, I’m sure he didn’t.

Reading Ruark or O’Connor, the best parts are rarely the actual kill, regardless of how big the trophy. It’s always what went before, what came after, and how much fun it all was - even if, perhaps, it did not seem so at the time.”

From the September 2018 HUNTING magazine article “Enough Gun for Elk” (Craig Boddington):

“Coming from me, this conclusion may shock you, so let me give you another surprise. I think Jack O’Connor, the great champion of the .270, would agree. He never questioned the adequacy of his .270 for elk, nor do I, but he was also a lifelong.30-06 fan and privately conceded its superiority for elk sized game.”

From the January/February 2019 RIFLE SHOOTER magazine article ‘Plenty of Gun’ (Craig Boddington):

“Jack O’Connor was a lifelong .375 fan, but he also had, among other big bores, a .416 Rigby.”

O'Connor believed in using the right rifle for the task at hand. Perhaps Bradford could comment on this but I've always believed Jack was more enamored of a particular rifle not so much the caliber of that rifle.
