Winchester branded the cartridge and introduced it to the commercial hunting market as the .308 Winchester. The dimensions of .308 Winchester are almost the same as 7.62×51mm NATO. The chamber of the former has a marginally shorter headspace and thinner case walls than the latter due to changed specifications between 1952 and 1954.
The 7.62 mm designation refers to the internal diameter of the barrel at the lands (the raised helical ridges in rifled gun barrels). The actual bullet caliber is often 7.82 mm (0.308 in), although Soviet weapons commonly use a 7.91 mm (0.311 in) bullet, as do older British (.303 British) and Japanese (7.7×58mm Arisaka) cartridges.
The .308 Winchester has a 3.64 mL (56 gr H 2 O) cartridge case capacity. [9] The exterior shape of the case was designed to promote reliable case feeding and extraction in bolt-action rifles and machine guns alike, under extreme conditions. .308 Winchester maximum C.I.P. cartridge dimensions. All dimensions in millimeters (mm) and inches.
The below table gives a list of firearms that can fire the 7.62×51mm NATO cartridge. This ammunition was developed following World War II as part of the NATO small arms standardization, it is made to replicate the ballistics of a pre-WWII full power rifle cartridge in a more compact package. Not all countries that use weapons chambered in this ...
The difference in diameter is less than 1/128 of an inch (0.2 mm), or approximately the thickness of two human hairs. [32] In addition, both the 6.8 × 51mm and the 7mm-08 Remington share the same parent case of the 7.62x51mm NATO, necked down to accept the respective bullet of each cartridge. [32]
The 308 Winchester and 7.62X51 are identical cartridgesThe cartridege was developed in the USA as a commercial round with an Imperial measurement ie .308 inches.The cartridge was adopted in Europe where all military calibers- even in the UK who still use miles instead of kilometres- all calibers are metric hence 7.62x51 millimetres.
An intermediate cartridge is a rifle/carbine cartridge that has significantly greater power than a pistol cartridge but still has a reduced muzzle energy compared to fully powered cartridges (such as the .303 British, 7.62×54mmR, 7.65×53mm Mauser, 7.92×57mm Mauser, 7.7×58mm Arisaka, .30-06 Springfield, or 7.62×51mm NATO), and therefore is ...
This evolved into the 7.62×40mm CETME M53, which was identical aside from the smaller diameter bullet. Eventually [when?] they decided on a variant of the new 7.62×51mm NATO cartridge that they designated the 7.62×51mm CETME. The 7.62mm CETME had a lighter full-metal-jacketed, plastic-cored lead bullet with a reduced powder charge.
