Frankly, I never bought into this hypothesis, and as the legend grew I became even more skeptical, firmly believing that the core reason for the success of the .243 Win. was the rifle in which it was initially offered: Winchester's immensely popular M-70. I've even stuck my neck out a few times with the suggestion that if the calibers had been reversed, with Winchester offering a .244-like caliber, 1-in-12-inch twist and all, it would still have been the winner because of the popularity of the rifle. By contrast, Remington's M-722 was a plain-looking thing with no checkering and a stamped and bent sheet-metal trigger guard. Accurate yes, at least on a par with the accuracy of a typical M-70, but those were the postwar days, when riflemen tended to dote on Mausers and '03 Springfields, of which the M-70 was kin and heir. Remington's "new look," an almost total abandonment of its prewar models, had yet to gain the widespread acceptance that would come later.
