Had the Whelen came out in the 1930's by Winchester it would be more popular than it is today. The powders were available for it then ( 4064, 4320, and 4895), and Roy Weatherby hadn't changed any minds yet. By the 1950's, shooters had changed. Powders like 4831 and 4350 had changed the playing field, and the riflescope made the playing field somewhat more even. Once the great .338 Winchester had arrived, the Whelen did not have a hope. The competition with the .338 Winchester and the .375 H&H was too great. Winchester backed the .338 and the .375. Loaded ammo could be purchased anywhere. The loading companies took note and delivered good bullets, and reloading equipment that extended their versatility. The Whelen had Remington dip their toe in the water at best. Too little, too late.
