As seen at the outstanding Internet web site isegoria.net and as extracted from same:
"The .276 Garand That Almost Was"
"Ian of Forgotten Weapons shows off the .276 Garand that almost was, the T3E2:"
"By 1932, the competition for the new US semiautomatic service rifle had been narrowed down to just two designs: John Pedersen’s delayed blowback toggle action and John Garand’s gas-operated action. Both rifles were chambered for Pedersen’s .276 caliber cartridge, and used 10-round en bloc clips. Twenty samples of each were made and sent out to infantry and cavalry units for field testing."
". . . The results of the trial was a preference for the Garand rifle, and the testing board got as far as writing a formal recommendation for its adoption before General MacArthur vetoed the whole .276 caliber idea for economic and logistical reasons (the US Army had a whole lot of .30-06 ammo and not a lot of spare cash). The result was ultimately a .30 caliber Garand rifle becoming the M1"
THE UNITED STATES ARMY INFANTRY DURING BOTH WW2 AND KOREA FOUGHT USING SMALL ARMS FIRING THAT THIRTY CALIBER ROUND IN TOTALITY!
That Garand rifle, the BAR [Browning Automatic Rifle] and the M1919 light machine-gun all having a commonality of ammunition, interchangeable!
THERE IS GREAT MERIT TO THIS AND IS NOT MERELY A COST SAVING MEASURE?
In this regard Mac Arthur cannot be faulted?
