One of the interesting finds pointed out to me by an ammunition collector at Knob Creek is this interesting tidbit of history. The .5 Vickers is a semi rimmed round that was invented in the last year of World War One by necking down a .600 Nitro Express round. It was intended for the water cooled Vickers heavy machine gun and was initially needed for anti-aircraft gunners to take down German bombers over London that could sustain multiple hits from the .303 cartridge being fired by Vickers anti-aircraft crews at the time. Although the round is the same caliber as the 50 BMG, the two are not interchangeable.
