Does anyone have a definitive answer as to Keith and Whelen being exposed to 9.3x62 and "conveniently" forgetting you don't need a 30-06 as a basis of a larger cartridge in .357 or .366 bore? I have one cow elk with 35 Whelen and one black bear with 9.3x62 so I am firmly in both camps.
Keith knew about the 9.3x74Rimmed cartridge and proceeded to make a 338 out of it....
Early on he did like the 9mm Mauser rifle cartridge.
I would suspect bullet and case availability to be the major problem of the time in regards to the 9.3x62
