Prototype Winchester WW1 .50 Cal Antitank Rifle
This video explores a rare prototype Winchester antitank rifle developed in late 1918, in response to the advent of tanks in World War I. The rifle, the only known surviving example, suffered a catastrophic failure during testing, with its receiver cracked in half. The description highlights its unique 1911-style pistol grip bolt handle and its role in the development of the .50 BMG cartridge, with captured German Tankgewehrs serving as the basis for US efforts. The video thanks the Cody Firearms Museum for access.
