.50 BMG

The .50 Browning Machine Gun (.50 BMG) or 12.7×99mm NATO is a cartridge developed for the Browning .50 caliber machine gun in the late 1910s. Entering service officially in 1921, the round is based on a greatly scaled-up .30-06 cartridge. Under STANAG 4383, it is a standard cartridge for NATO forces as well as many non-NATO countries. The cartridge itself has been made in many variants: multiple generations of regular ball, tracer, armor-piercing, incendiary, and saboted sub-caliber rounds. The rounds intended for machine guns are linked using metallic links.

The .50 BMG cartridge is also used in long-range target and sniper rifles, as well as other .50-caliber machine guns. The use in single-shot and semi-automatic rifles has resulted in many specialized match-grade rounds not used in .50-caliber machine guns. A McMillan Tac-50 .50 BMG sniper rifle was used by Canadian Army Corporal Rob Furlong of the PPCLI to achieve what was then the longest-range confirmed sniper kill in history, when he shot a Taliban combatant at 2,430 meters (2,657 yards) during the 2002 campaign in the Afghanistan War. (This was surpassed in 2009 by a British sniper in Afghanistan with 2,475 meters (2,707 yards) using a .338 Lapua Magnum (8.58×70 mm) rifle.)

IMI Desert Eagle

The IMI Desert Eagle is a semi-automatic handgun notable for chambering the largest centerfire cartridge of any magazine fed, self loading pistol. It has a relatively unique design with a triangular barrel and large muzzle. MRI is the most recent company to design and develop the Desert Eagle, having done so for more than 25 years. The design was refined and the actual pistols were manufactured by Israel Military Industries until 1995, when MRI shifted the manufacturing contract to Saco Defense in Saco, Maine. In 1998, MRI moved manufacturing back to IMI, which later reorganized under the name Israel Weapon Industries. Since 2009, the Desert Eagle Pistol has been produced in the United States at MRI's Pillager, MN facility. Kahr Arms acquired Magnum Research in the middle of 2010. The Desert Eagle has been featured in roughly 500 motion pictures and TV films, along with several video games (especially the Resident Evil series, Counter-Strike series, Grand Theft Auto series), and Call Of Duty series, making it well known in popular culture.

.50 Action Express

The .50 Action Express (AE, 12.7×33mm) is a large caliber handgun cartridge. It was developed in 1988 by Evan Whildin of Action Arms. The .50 AE is one of the most powerful pistol cartridges in production.

Overview

The Magnum Research Desert Eagle was the first handgun chambered for the .50 AE. The actual cartridge has a .547 inch (13.9 mm) diameter base, with a rebated rim. The rim diameter of the .50 AE is the same as the .44 Remington Magnum cartridge. A Mark XIX Desert Eagle in .50 AE can be converted to .44 with nothing more than a barrel and magazine change. The .357 and .44 Mark VII guns have a smaller frame and can not be converted to .50 AE without the fitting of a Mark XIX slide assembly and a few other miscellaneous parts at the factory. Any Mark XIX Desert Eagle can be converted to .50 AE, but the .357 model will require a new bolt, barrel, and magazine; some hand-loaders turn their rims down to .357 Magnum dimensions, so that only a new barrel and magazine are needed.
