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., is a .50 in mm 1 caliber cartridge developed for the M2 Browning heavy machine gun in the late 1910s, entering official service in 1921. Under STANAG 4383, it is a standard service cartridge for NATO forces. The cartridge itself has been made in many variants: multiple generations of regular ball, tracer, armor-piercing (AP), incendiary, and saboted sub-caliber penetrator rounds. The rounds intended for machine guns are made into a continuous ammunition belt using metallic links.
The .50 BMG cartridge is also used in anti-materiel rifles. A wide variety of ammunition is available, and the availability of match grade ammunition has increased the usefulness of .50 caliber rifles by allowing more accurate fire than lower-quality rounds.Sweeney Patrick Gun Digest Book of Suppressors https://books.google.com/books?id=9nr5CgAAQBAJ&pg=PA177 December 21, 2015 F+W Media Iola, Wisconsin 978-1-4402-4540-4 177
History
In response to the need for new anti-aircraft weaponry during World War I, John Browning developed the .50 BMG. He wanted the round to be used in a machine gun based on a scaled-up version of the M1917 Browning.Skinner Stan Shooter's Bible Guide to Extreme Iron https://books.google.com/books?id=ZQYHBAAAQBAJ&pg=PT172 November 20, 2013 Skyhorse Publishing Company, Incorporated 978-1-62873-538-3 172
The development of the .50 BMG round is sometimes confused with the German 13.2 mm TuF, which Germany developed for an anti-tank rifle to combat British tanks during World War I and against aircraft. According to American Rifleman:
the Browning .50 originated in the Great War. American interest in an armor-piercing cartridge was influenced by the marginal French 11 mm design, prompting U.S. Army Ordnance officers to consult Browning. They wanted a heavy projectile at 2700 feet per second (f.p.s), but the ammunition did not exist. Browning pondered the situation and, according to his son John, replied, "Well, the cartridge sounds pretty good to start. You make up some cartridges and we'll do some shooting."The .50-cal. Browning Machine Gun—The Gun That Won The War https://www.americanrifleman.org/content/the-50-cal-browning-machine-gun-the-gun-that-won-the-war/ American Rifleman National Rifle Association of America 23 February 2017 8 May 2026 en
The American Rifleman further explains that development was:
[r]eputedly influenced by Germany's 13.2×92 mm SR (.53-cal.) anti-tank rifle, Ordnance contracted with Winchester to design a .50-cal. cartridge. Subsequently, Frankford Arsenal took over from Winchester, producing the historic .50 BMG or 12.7×99 mm cartridge. The Army then returned to John Browning for the actual gun. Teamed with Colt, he produced prototypes ready for testing and, ironically, completed them by Nov. 11, 1918—the Great War's end.
The round was put into use in the M1921 Browning machine gun. This gun was later developed into the M2HB Browning, which, with its .50 caliber armor-piercing cartridges, went on to function as an anti-aircraft and anti-vehicular machine gun, capable of penetrating 0.9 inch mm of face-hardened armor steel plate at 200 meters yards flip,MCWP 3-15.1 Machine Guns and Machine Gunnery https://archive.org/details/milmanual-mcwp-3-15.1-machine-guns-and-machine-gunnery/page/n183/mode/2up archive.org US Marine Corps 1 inch mm of rolled homogeneous armor at the same range,Browning Machine Gun Caliber .50 HB, M2 https://www.bits.de/NRANEU/others/amd-us-archive/FM23-65C2%2802%29.pdf bits.de Headquarters Department of the Army April 15, 2020 August 19, 2020 https://web.archive.org/web/20200819212746/https://www.bits.de/NRANEU/others/amd-us-archive/FM23-65C2%2802%29.pdf live and 0.75 inch mm at 547 yards meters.Barnes, Frank C.

During World War II, the .50 BMG was primarily used in the M2 Browning machine gun, in both its "light barrel" aircraft mount version and the "heavy barrel" (HB) version on ground vehicles, for anti-aircraft purposes. An upgraded variant of the M2 Browning HB machine gun used during World War II is still in use today. Since the mid-1950s, some armored personnel carriers and utility vehicles have been designed to withstand 12.7 mm machine-gun fire, thereby limiting the destructive capability of the M2. It still has more penetrating power than lighter weapons such as general-purpose machine guns, though it is significantly heavier and more cumbersome to transport. Its range and accuracy, however, are superior to light machine guns when fixed on tripods. It has not been replaced as the standard caliber for Western vehicle-mounted machine guns (Soviet and CIS armored vehicles mount 12.7×108mm NSVs, which have similar dimensions to .50 BMGs).
Decades later, the .50 BMG was chambered in high-powered rifles as well. The Barrett M82 rifle was developed during the 1980s and, along with later variants, has upgraded the anti-materiel power of the military sniper.
Typical uses
The primary military use of this round is in the M2 Browning machine gun and anti-materiel rifles such as the Barrett M82.McNab Chris The Barrett Rifle: Sniping and Anti-materiel Rifles in the War on Terror Bloomsbury Publishing 2016 9781472811028
The U.S. Coast Guard uses .50 BMG rifles onboard armed helicopters to disable the engines on boats during interdictions. Similarly, .50 BMG weapons have attracted attention from law enforcement agencies; they have been adopted by the New York City Police Department and the Pittsburgh Police. A .50 BMG round can effectively disable a vehicle when fired into the engine block. A .50 BMG round will penetrate most commercial brick walls and concrete cinder blocks.https://www.youtube.com/watch?v=aX05bSn59uo 50 BMG vs Concrete Wall 2017-12-14 Kentucky Ballistics 2025-02-19 YouTube
The .50 BMG round was used as a sniper round as early as the Korean War.Senich Peter R. U.S. Marine Corps Scout-sniper: World War II and Korea 1993 Paladin Press Boulder 978-0-87364-710-6 225–227 Several world records for the longest confirmed kills were set with the .50 BMG. Eventually, purpose-built sniper rifles were developed specifically for this round.Walter John The Sniper Encyclopaedia: An A-Z Guide to World Sniping 2019 en-US
In addition to long-range and anti-materiel, the U.S. military uses .50 BMG weapons to detonate unexploded ordnance from a safe distance. It can disable most unarmored and lightly armored vehicles.Cutshaw Charles Q.

Power
A common method for understanding the actual power of a cartridge is the comparison of muzzle energies. The .30-06 Springfield, the standard caliber for American soldiers in both World Wars and a popular caliber amongst American hunters for medium to large game animals, can produce muzzle energies between 2,000 and 3,000 ftlbf 1 in. The .50 BMG round can produce between 10,000 and 15,000 ftlbf, depending on its powder and bullet type, as well as the weapon it is fired from. Due to the high ballistic coefficient of the bullet, the .50 BMG's trajectory also suffers less "drift" from crosswinds than smaller and lighter calibers, making the .50 BMG a good choice for high-powered sniper rifles.Michaelis Dean The Complete .50-caliber Sniper Course: Hard-Target Interdiction March 1, 2000 Paladin Press Boulder, Colorado 978-1-58160-068-1 26–34

United States
The specified maximum diameter of an unfired .50 BMG bullet is 0.510 in mm; while this appears to be over the .50 inch (12.7 mm) maximum allowed for non-sporting Title I firearms under the U.S. National Firearms Act, the barrel of a .50 BMG rifle is only .50 inch (12.7 mm) across the rifling lands and slightly larger in the grooves. The oversized bullet is formed to the bore size upon firing, forming a tight seal and engaging the rifling. Despite political controversy over the cartridge's great power (it is the most powerful commonly available cartridge not considered a destructive device under the National Firearms Act), it remains popular among long-range shooters for its accuracy and external ballistics. While the .50 BMG round can deliver accurate shot placement (if match grade ammunition is used) at ranges over 1000 yd on, smaller-caliber rifles produce better scores and tighter groups in 1000 yd on competitions.http://www.gunweek.com/2006/feature0420.html SHOT Show 2006 New Rifles, Shotguns, Pistols Offer Enhanced Performance GunWeek.com April 10, 2008 https://web.archive.org/web/20080521043310/http://www.gunweek.com/2006/feature0420.html May 21, 2008 dead

Contrary to a persistent misconception within the United States Armed Forces, using .50 BMG directly against enemy personnel is not prohibited by the laws of war. http://www.mca-marines.org/gazette/killing-myth Killing A Myth Parks Maj W. Hays January 1988 Marine Corps Gazette February 20, 2014 https://web.archive.org/web/20140228114414/http://www.mca-marines.org/gazette/killing-myth February 28, 2014 dead mdy-all Writing for the Marine Corps Gazette, Major Hays Parks states: "No treaty language exists (either generally or specifically) to support a limitation on [the use of .50 BMG] against personnel, and its widespread, longstanding use in this role suggests that such antipersonnel employment is the customary practice of nations." Parks theorizes that the misconception originated in historical doctrine discouraging the use of the M8C spotting rifle—an integral .50-caliber aiming aid for the M40 recoilless rifle—in the antipersonnel role. This limitation was entirely tactical and intended to hide the vulnerable M40 and its crew from the enemy until the main anti-tank gun was ready to fire; however, Parks concludes that some U.S. troops assumed the existence of a legal limitation on the use of .50-caliber projectiles more generally.
