Rare Box US Military .276 Pederson Ammunition

 Very rare box of .276 Pederson ammunition manufactured at Frankford arsenal in 1929. Box is unopened but has seen considerable stress hence the clear wrap to keep it intact.

Developed in 1923 in the United States, the .276 was intended to replace the .30-06 Springfield in new semi-automatic rifles and machine guns. When first recommended for adoption, M1 Garand rifles were chambered for the .276 Pedersen, which held ten rounds in its unique en-bloc clips. The .276 Pedersen was a shorter, lighter and lower pressure round than the .30-06, which made the design of an autoloading rifle easier than the long, powerful .30-06. The U.S. Army Chief of Staff Gen. Douglas MacArthur rejected the .276 Pedersen Garand in 1932 after verifying that a .30-06 version was feasible.
