1918-2018 – 100 years of the Mauser 13 mm anti-tank and anti-aircraft rifle

Vlim,

I have been told for years that the 50 BMG round was based on the 30-06 cartridge. John Browning just upscaled the design to .50 caliber. Perhaps this complements rather than conflicts with the story of the Mauser tank round.
