The .308 Winchester
.308 Winchester
(pronounced: "three-oh-eight") is a rimless, bottlenecked rifle cartridge and is the commercial cartridge from which the 7.62×51mm NATO
7.62×51mm NATO
round was derived. The .308 Winchester
.308 Winchester
was introduced in 1952, two years prior to the NATO

adoption of the 7.62×51mm NATO
7.62×51mm NATO
T65. Winchester branded the cartridge and introduced it to the commercial hunting market as the .308 Winchester. Winchester's Model 70 and Model 88 rifles were subsequently chambered for the new cartridge. Since then, the .308 Winchester
.308 Winchester
has become the most popular short-action, big-game hunting cartridge worldwide.[2] It is also commonly used for civilian hunting, target shooting, metallic silhouette, bench rest target shooting, palma, metal matches, military sniping, and police sharpshooting. The relatively short case makes the .308 Winchester
.308 Winchester
especially well-adapted for short-action rifles. When loaded with a bullet that expands, tumbles, or fragments in tissue, this cartridge is capable of high terminal performance.[3][4][5] Although very similar to the military 7.62×51mm NATO
7.62×51mm NATO
specifications, the .308 cartridge is not identical, and there are special considerations that may apply when mixing these cartridges with 7.62×51mm NATO, and .308 Winchester
.308 Winchester
chambered arms.[6] Their interchange is, however, considered safe by the Sporting Arms and Ammunition Manufacturers Institute (SAAMI).[7]

Cartridge dimensions[edit] The .308 Winchester
.308 Winchester
has 3.64 ml (56.0 grains) cartridge case capacity.[8] 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.

cartridge dimensions. All dimensions in millimeters (mm) and inches. Americans would define the shoulder angle at alpha/2 = 20 degrees. The common rifling twist rate for this cartridge is 305 mm (1 in 12 in), 4 grooves, Ø lands = 7.62 mm, Ø grooves = 7.82 mm, land width = 4.47 mm and the primer type is large rifle.[9] According to the official C.I.P.

.308 Winchester
is one of the most popular hunting cartridges in the United States, and possibly the world. It has gained popularity in many countries as an exceptional cartridge for game in the medium- to large-sized class.[12] In North America
North America
it is used extensively on whitetail deer, pronghorn and even the occasional caribou or black bear. Clay Harvey, an American gun writer, says it is usable on moose and elk.[13] Layne Simpson, an American who has hunted in Sweden, says he is surprised how many hunters there use the cartridge.[14] Craig Boddington was told by a Norma Precision executive that the .308 Winchester is one of Norma's best-selling calibers.[15] In Africa

is one of the most popular calibers among Bushveld

hunters and is used on anything from duiker right up to the massive eland (a small and large African antelope respectively). Proponents of the hydrostatic shock theory contend that the .308 Winchester has sufficient energy to impart hydrostatic shock to living targets when rapidly expanding bullets deliver a high rate of energy transfer.[3][5][16][17] While .308 Winchester
.308 Winchester
has traditionally been the most popular cartridge in the past, the development of lighter recoil chamberings with sufficient downrange energy, like the 7mm-08 Remington, .260 Remington, and 6.5 Creedmoor, is becoming more common for metallic silhouette shooting.[18] The PALMA shooting is a variant of full bore target shooting done with a bolt action rifle in 7.62mm NATO

caliber (.308 Winchester) and fire Match Grade 155 grain bullets using micrometer aperture (iron) sights at out to 1,000 yards.[19] F-Class is a variant of Fullbore Target Rifle

which permits optical telescopic sights and shooting rests in the front and rear like for instance like a bipod and/or bags. Competitions are fired at distances between 300 and 1200 meters (or yards), and the targets are half the size of those used in traditional Palma shooting. Based on equipment, competitors can choose to compete in one of the two classes Open or Standard: F-TR ("Target", Standard Class): A restricted class permitting a scope, bipod/ backpack and rear bag (no front rest), but the rifle has to be of either caliber .223 Remington or .308 Winchester. In addition, the weight limit including optics is 8.25 kg (18.15 lbs).[citation needed] The .308 Winchester
.308 Winchester
has slightly more drop at long range than the .30-06 Springfield, owing to its slightly lower (around 30 metres per second (100 ft/s)) muzzle velocity with most bullet weights. Cartridges with significantly higher muzzle velocities, such as the .300 Winchester Magnum
.300 Winchester Magnum
can have significantly less drop at long range, but much higher recoil.

Several more cartridges have been developed using the .308 Winchester as a parent case, some becoming very popular for hunting, particularly in North America.[9] These are the .243 Winchester, the .260 Remington (a.k.a. 6.5-08 A-Square), the 7 mm-08 Remington, the .338 Federal, and the .358 Winchester

(a.k.a. 8.8×51mm). In 1980, two rimmed cartridges based on the .308 Winchester
