The .50 BMG (.50 Browning Machine Gun), also known as 12.7×99mm NATO, and designated as the 50 Browning by the C.I.P., [1] is a .50 in (12.7 mm) caliber cartridge developed for the M2 Browning heavy machine gun in the late 1910s, entering official service in 1921.
With normal bullet weights between 300 and 400 grains (19 and 26 g), overall cartridge length shorter than that of an AR-15 magazine well, and holding to pressures of 33,000 psi limited by the AR bolt strength system, [2] the .50 Beowulf is best described as a low-velocity, heavy caliber, making its ballistics roughly equivalent to those of ...
In a side-by-side comparison with the .50 BMG (43 g), the 15 gr (1 g) titanium round of any caliber released almost 2.8 times the energy of the .50 BMG (1 g at 10 000 m/s = 50 000 joules), with only a 27% mean loss in momentum. Energy, in most cases, is what is lethal to the target, not momentum.
Winchester improved the .50 caliber round to have similar performance. Ultimately, the muzzle velocity was 2,750 ft/s (840 m/s). [25] Efforts by Browning and Fred T. Moore resulted in the water-cooled, .50 caliber M1921 Browning machine gun and an aircraft version. These guns were used experimentally from 1921 until 1937.
Common rifle cartridges, from the largest .50 BMG to the smallest .22 Long Rifle with a $1 United States dollar bill in the background as a reference point.. This is a table of selected pistol/submachine gun and rifle/machine gun cartridges by common name.
The .50-90 Sharps is similar to the .50-100 Sharps and .50-110 Sharps cartridges. All three use the same 2.5-inch (64 mm) case, the latter two being loaded with more grains of black powder. All rifles made for the .50-90 Sharps should be able to use the .50-110 and .50-100 cartridges due to the case dimensions being nearly identical.
The fixed price for a traditional Hawken rifle was $22.50 - $25.00. Several of the fine engraved Hawken rifles sold for $38 between 1837-1842. A .70 caliber Hawken rifle, the largest caliber example known, that was once owned by Theodore Roosevelt and is set for auction in May of 2024 has an estimated auction value of US$55,000 to US$85,000.
