Whelen was a colonel in the United States Army, contributing editor to Sports Afield, American Rifleman, Field and Stream, Outdoor Life, Guns & Ammo, and other magazines, and author of Telescopic Rifle Sights, The Hunting Rifle, Small Arms and Ballistics, Hunting Big Game (of which he was the editor), Amateur Gunsmithing, and Why Not Load Your Own. An autobiography, Mr. Rifleman, was begun by Whelen, but finished by his family and published after his death. He was a major influence in the autobiography of Walter Bell called Bell of Africa as explained in the introduction of that book. Bell had died in 1954 whilst working on his autobiography. Whelen edited and finished the work and wrote the introduction. An expert rifleman with few peers, Whelen could reportedly hit man-sized target at 200 yards using the bolt action, open-sighted M1903 Springfield .30-06 service rifle, scoring six hits in ten seconds flat, and could do it on command.
Colonel Whelen experimented with the service .30-06 Springfield cartridge while he was commanding officer of Frankford Arsenal in the early 1920s. Frankford Arsenal machine shop foreman James Howe, who later formed the rifle-making firm of Griffin & Howe, assisted Whelen modifying the .30-06 case to fire bullets of different calibers. Whelen was particularly interested in creating a cartridge to fire heavier bullets from M1903 rifle actions available from the Civilian Marksmanship Program.
