Winchester WWII 50 AT rifle
This video discusses the undesignated Winchester .50 BMG semi-automatic antitank rifle developed during World War II. It highlights David Marshall Williams' involvement and the rifle's mechanical features, including its Garand-type rotating bolt and gas tappet short stroke action. The rifle used a 10-round detachable box magazine. Although tested by the Canadian military and performing well, it was never put into production, likely due to the .50 BMG cartridge's diminishing effectiveness against tanks by the war's end. The description also references other Winchester projects like the M1 Carbine and G30 series rifles.
