I agree with Bettis, you use the name Elmer Keith and....
Start reading the books he co-wrote. But, I will suggest you take it with a grain of salt.
Then read of Jack O'Conner's books. For more salt.
Jack O'Connor pushed the .270 and will be remembered for that. Beyond that, his name should not be mentioned along with that of Elmer Keith.
Aside from Mr. O'Connor's odd personality as compared to Keith's jovial and friendly manner, Keith had a broad base of experience and knowledge across the disciplines of shotgunning, rifles and hunting and, of course, handguns and handgun hunting. Keith's experience was far more broad than O'Connor. Keith certainly had a less polished writing style, but what he lacked in form was easily made up in substance. Thus, while O'Connor should have his due for his conservation efforts and his promotion of the .270 rifle cartridge, there is just no doubt that he and Keith did not play in the same ball park.
About the most they had in common was that they both wrote articles for gun magazines. Keith was an experimenter who came up with new ideas for ammo and guns, and he got companies to bring his ideas to the general public.
Thus, while O'Connor is remembered as Mr. Outdoor Life and for his conservation efforts and his sheep hunting and promotion of the .270, Keith is remembered for his involvement with the .357 Magnum, the .44 Magnum and the .41 Magnum revolvers and cartridges and for a host of other things related to hunting, shooting, safaris and the like. Keith pushed rifle calibers in the .338 range and could never really understand why the .270 should be used instead of a .30-06.
It really doesn't make good sense, does it? They are both long actions, but the "ought-six" takes a wider range of bullet weights and can do more, all in a rifle of equal weight and identical features. Thus, why would you really want a less versatile rifle?
Oh well, it doesn't really matter. The evidence is right in front of us. O'Connor barely gets mentioned in articles these days, while there is still a "larger than life" fascination with Elmer.
