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.[2]
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 VII 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. Any Mark XIX Desert Eagle can be converted to .50 AE, but the .357 model will require a new bolt, barrel, and magazine.
The introduction of the .50AE in the US was met with a rocky start. US laws state that non-sporting firearms may not be over 0.500" in bore diameter (measured land to land) to meet title I regulations. The original .50 Action Express bore diameter was .500" with conventional rifling, but the switch to polygonal rifling on production Desert Eagles Pistols allowed the gauge plug to drop through, rendering the gun a destructive device under Bureau of Alcohol, Tobacco, Firearms and Explosives (BATFE) regulations. Nominal bullet diameter was reduced to the current 0.500 inch (12.7 mm) rather than the original .510".[3] Thus the noticeably tapered case.
Loaded .50 AE ammunition is currently available from CCI Ammunition, Speer, and IMI with the latter ammunition being imported into the US by Magnum Research under the "Samson Ultra" trademark. Fired from a standard six-inch Desert Eagle barrel, Speer's 300-grain load produces a muzzle velocity of over 1,500 ft/s, giving a muzzle energy of over 1,500 ft⋅lb (2,000 J).[4] Fired from a 10-inch barrel, the same load produces a muzzle velocity of over 1,600 ft/s, giving a muzzle energy of nearly 1,800 ft⋅lb (2,400 J).[4]
Recoil of the .50 AE in the Desert Eagle pistol is substantial, although only marginally more severe than the .44 Magnum, as the auto mechanism and weight of the gun smooth the recoil somewhat. Other firearms chambered for the .50 AE include the AMT AutoMag V, LAR Grizzly Win Mag, Freedom Arms model 555, and the Magnum Research BFR.
Performance
SAAMI specifies a maximum chamber pressure of 36,000 psi (248 MPa) for the .50 AE. Available factory loads can produce nearly 1,800 ft·lbf (2440 J) of muzzle energy.[4] Currently, only IMI (Samson), Speer/CCI, and Hornady manufacture .50 AE.[3] New, unprimed brass is available from Starline. Bullets are available from a few different manufacturers. Many of the bullets designed for the .500 S&W Magnum are too long for use in .50 AE semi-automatic pistols.
Use
Like other handgun cartridges of such magnitude, the principal uses of the .50 AE are metallic silhouette shooting and medium/big game hunting. It is unnecessarily powerful for tactical/defensive use, and the resulting heavy recoil and excessive muzzle flash actually make it less desirable than smaller cartridges for such purposes. However, like the .44 Magnum, .454 Casull, .460 S&W Magnum, and .500 S&W Magnum, it is well suited for defense against large predators, such as bears.[5]
