One Cartridge, Not a Box: .50 BMG (50 Caliber Browning Machine Gun) Slavo Squeeze Bore from Colt industries, used in internal experiments in the early 1970s.
The 5 projectiles (copper alloy) had a total weight of 710 grains, were enclosed in a plastic nylon shrink-wrap, then loaded into military cases from Twin Cities Ordnance Plant, Minneapolis, Minnesota with a “45 TW” head-stamp.With an approximate muzzle velocity of 3,000 feet per second, the fired projectiles would disperse over a 30 foot area at 600 yards, basically making this a long range scatter gun. To my limited knowledge, problems with barrel-wear and other issues ended the experiments and the program was never adopted.In the interest of historical accuracy, please feel free to correct me if I am wrong.
History of the .50 BMG cartridge:This is one of the most successful military cartridges of all time. This cartridge was invented in 1918 by John Browning, the .50 BMG, also known as the 50 Browning for the 50 Browning Machine Gun.Also known as the 12.7x99mm in Europe, has been used extensively in almost every U.S.A. conflict since its adoption in 1923.Adopted by the U.S. Military in 1923 the .50 BMG has been used longer than any other cartridge in military history. (Note: The .45 ACP is actually older, but was technically superseded.) Technically the .50 BMG is the biggest cartridge available to shooters without encumbrance legal restrictions. (There are other wider diameter cartridges, but none larger available)
