Jack O'Connor; America's greatest gun writer
Beginning in 1934 and flowing continuously from 1937 until his Outdoor Life retirement in 1972 and afterwards, American sportsmen read the words of gun writer Jack O'Connor. If you asked any WWII veteran who hunted afterwards if he'd ever heard of Jack O'Connor, you'd get the remark, "Oh, yeah, he's the .270 guy!" Indeed he was. Largely through his accounts of one-shot kills with a Model 54 Winchester in .270 Winchester, he popularized this single caliber.
