Reply #20: It's NOT a .50

[one-eyed fat man]

If you are still talking about the picture with the smug chica in the purple pants. It is a Browning M1919A4 and from the looks of the belt, it is in .30-06. .30-06 was the US service cartridge from 1903 until 1957 and also Mexican service cartridge up through 80's. The US government furnished the Mexican government with box car loads of them. It was chambered for a wide variety of military cartridges including .303 British, 7.65 Argentine, 7.65 Belgian, 7x57 Mauser, 8x57 Mauser, 7.62 NATO, 6.5x55 Swede, and 7.62x54R Russian.

One of the advantages of having an M1919 series gun is that they also made cloth belts an addition to the disintegrating metal link belts like in the picture. The bolt face on the .30-06 caliber gun accommodates rimless cartridges with a .473 head diameter. By simply changing barrels and setting the headspace correctly the gun can easily be converted to shoot 7.62 NATO, or 8mm Mauser. The same applies to the M1917 water-cooled version.

Most of the 1919's were left hand feed with the charging handle on the right. The last of the series, the M37 which saw US service primarily as a tank coax machinegun had a bolt and feed that was switchable and could be fed from either side. There some of these Browning design guns still in service that sixty and seventy years old and work as well now as the day they were built.
