The Pedersen device was an experimental weapon attachment for the M1903 Springfield bolt action rifle that allowed it to fire a .30 caliber (7.62 mm) pistol-type cartridge in semi-automatic fire mode.
The cartridge did, however, make a reasonably light yet effective semiautomatic rifle possible. By early 1926, Pedersen had designed and built a prototype rifle. He had researched Army tactics and operational concepts, and had engineered the tooling for parts manufacture as an integral part of engineering the gun parts themselves.
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. [2]
A pump-action centerfire rifle was a peculiar choice to compete with a lever action. Most hunters preferred the simple lever-operated repeating rifles produced by Winchester, Marlin, and Savage. Remington tried to take the high ground by introducing the John Browning designed semi-automatic Model 8 in 1906, along with a new line of cartridges ...
Pedersen device drawing. During World War I, the United States secretly developed the Pedersen device attachment for the M1903 Springfield rifle that allowed it to fire the .30-18 Auto (7.65×20mm Longue) pistol cartridge in semi-automatic mode.
John Douglas Pedersen (May 21, 1881 – May 23, 1951) was a prolific arms designer who worked for Remington Arms, and later for the United States Government.Famed gun designer John Moses Browning told Maj.

The US .30 Pedersen cartridge (auto pistol ball cartridge caliber .30 Model of 1918 or .30-18 Automatic) used in the Pedersen device was the basis for the 7.65×20mm Long. The cartridge dimensions were identical, although Pedersen device cartridges were loaded with a slightly heavier 80 grains (5.2 g) bullet which achieved a velocity of 1,300 ...
