Шаблон:Short description Шаблон:Infobox firearm cartridge
The .30 Carbine (7.62×33mm) is a rimless carbine/rifle cartridge used in the M1 carbine introduced in the 1940s. It is a light rifle round[1][2][3][4] designed to be fired from the M1 carbine's 18-inch (458 mm) barrel.
History
Shortly before World War II, the U.S. Army started a "light rifle" project to provide support personnel and rear area units a weapon with more firepower and accuracy than the standard issue M1911A1 .45 ACP handgun and half the weight of the standard issue M1 Garand .30-06 rifle or the .45 ACP Thompson submachine gun.
The .30 Carbine cartridge was developed by Winchester and is basically a rimless .30 caliber (7.62 mm) version of the much older .32 Winchester Self-Loading cartridge of 1906 introduced for the Winchester Model 1905 rifle.[5] (The .30 Carbine's relatively straight case and round nose bullet have misled some to believe it was designed for use in pistols.) The .30 Carbine uses a lighter bullet (110 grain versus 165 grain) and improved powder. As a result, it has approximately 41% higher muzzle velocity with 27% more impact energy than the parent .32 WSL cartridge.
At first, Winchester was tasked with developing the cartridge but did not submit a carbine design. Other firms and individual designers submitted several carbine designs, but most prototypes were either unreliable or grossly off the target weight of five pounds. Army Ordnance Major Rene Studler persuaded Winchester that the Winchester M2 .30-06 rifle, a design started by Ed Browning and perfected by Winchester engineers including Marshall "Carbine" Williams, could be scaled down for the .30 Carbine cartridge. The result was the M1 carbine.[6]
The M1 carbine was issued to infantry officers; machine gun, artillery and tank crews; paratroopers; and other line-of-communications personnel in lieu of the larger, heavier M1 Garand. Cavalry Reconnaissance units were primarily armed with the carbine.[7] The weapon was originally issued with a 15-round detachable magazine. The carbine and cartridge were not intended to serve as a primary infantry weapon, nor was it comparable to more powerful intermediate cartridges later developed for assault rifles. The M2 carbine was introduced late in World War II with a selective-fire switch allowing optional fully automatic fire at a rather high rate (850–900 rpm) and a 30-round magazine.
The M1 and M2 carbines continued in service during the Korean War. A postwar U.S. Army evaluation reported that "[t]here are practically no data bearing on the accuracy of the carbine at ranges in excess of 50 yards. The record contains a few examples of carbine-aimed fire felling an enemy soldier at this distance or perhaps a little more. But they are so few in number that no general conclusion can be drawn from them. Where carbine fire had proven killing effect, approximately 95 percent of the time the target was dropped at less than 50 yards."[8] The evaluation also reported that "[c]ommanders noted that it took two to three engagements at least to settle their men to the automatic feature of the carbine so that they would not greatly waste ammunition under the first impulse of engagement. By experience, they would come to handle it semiautomatically, but it took prolonged battle hardening to bring about this adjustment in the human equation."[8]
Development
U.S. Army specifications for the new cartridge mandated the caliber to be greater than .27, with an effective range of 300 yards or more, and a midrange trajectory ordinate of Шаблон:Convert or less at 300 yards. With these requirements in hand, Winchester's Edwin Pugsley chose to design the cartridge with a .30 caliber, 100–120 grain bullet at a velocity of Шаблон:Convert. The first cartridges were made by turning down rims on .32SL cases and loading with .308 caliber bullets which had a similar profile to those of the U.S. military .45 ACP bullets. The first 100,000 cartridges manufactured were headstamped ".30 SL" (for "self-loading").[9]
Civilian use
The popularity of the M1 carbine for collecting, sporting, and re-enactment use has resulted in continued civilian popularity of the .30 Carbine cartridge. For hunting, it is considered a small-to-medium-game cartridge.[5]
Handguns
A number of handguns have been chambered for .30 Carbine ammunition. In 1944, Smith & Wesson developed a hand-ejector revolver to fire .30 Carbine. It went through 1,232 rounds without incident. From a four-inch (102 mm) barrel, it launched the standard GI ball projectile at Шаблон:Convert, producing an average group of Шаблон:Convert at Шаблон:Convert; the military decided not to adopt the revolver. The loud blast is the most oft-mentioned characteristic of the .30 Carbine cartridge when fired in a handgun.[10]
In 1958, the short-lived J. Kimball Arms Co. produced a .30 Carbine caliber pistol that closely resembled a slightly scaled-up High Standard Field King .22 target pistol. The Ruger Blackhawk revolver chambered for the .30 Carbine round has been in the catalogs since the late 1960s. Standard government-issue rounds reach over Шаблон:Convert, with factory loads, and handloads producing similar velocities or tuned for more efficient short-barrel performance without excessive blast.
Plainfield Machine Corp. made a .30 caliber pistol from 1964 to 1983 named the "Enforcer". While similar to the M1 carbine, it lacked the stock, thereby making it a handgun. Sold to Iver Johnson in 1983, the Enforcer continued in production until 1986. Other handguns chambered for this cartridge include the Thompson-Center Contender.
Plainfield Machine produced M1 carbines from 1960 to 1977, when they were bought out by Iver Johnson Corp, who has manufactured them at least until a 50th anniversary model in 1993. The Taurus Raging Thirty and AMT AutoMag III were also offered in .30 Carbine.[10]
Comparison
The .30 Carbine was developed from the .32 Winchester Self-Loading used in an early semi-auto sporting rifle. A standard .30 Carbine ball bullet weighs Шаблон:Convert; a complete loaded round weighs Шаблон:Convert and has a muzzle velocity of Шаблон:Convert, giving it Шаблон:Convert of energy when fired from the M1 carbine's 18-inch barrel.
By comparison, the .30-06 M2 cartridge for M1 Garand rifle fired a ball bullet weighing 152 grains (9.8 g) at a muzzle velocity of Шаблон:Convert and Шаблон:Convert of muzzle energy. Therefore, the M1 carbine is significantly less powerful than the M1 Garand. Another comparison is a .357 Magnum cartridge fired from an 18" rifle barrel, which has a muzzle velocity range from about Шаблон:Convert with energies at Шаблон:Convert for a Шаблон:Convert bullet at the low end and a Шаблон:Convert bullet on the high end.[11]

Cartridge types
Common types used by the military with the carbine include:
- Cartridge, caliber .30, carbine, ball, M1 - It originally came in cartons of 45 cartridges, divided into three fold-out sections of 15 rounds. The M1 Carbine had a magazine that contained exactly 15 rounds, so this prevented wastage or loss. It was changed to 50 rounds in 1942 to maximize the amount of ammo delivered.
- Cartridge, caliber .30, carbine, grenade, M6 [Crimped case] - The grenade blank was used with the M8 rifle grenade launcher. It came in individual-issue cartons of 6 cartridges or full cartons of 50 cartridges. The large cartons were made of plain chipboard and were bulk-packed in terneplate-lined wooden packing crates (later in metal "spam cans" from 1944). Individual-issue cartons were originally sealed and waterproofed with a wax coating and then packed in rifle grenade crates. This was found to be ineffective, as the seal would get broken in handling and compromise the contents to salt air and moisture. It was later replaced with a heat-sealed foil-lined kraftpaper wrapping.
From 1944 the M13 metal "spam can" was introduced. It was packed with an assortment of an individual 6-round carton of Carbine Grenade blanks M6, a 10-round carton of .30-06 Springfield Rifle Grenade blanks M3, and a 5-round packet of Grenade Auxiliary M7 cartridges. - Cartridge, dummy, caliber .30, carbine, M13 - The cartridge had one hole drilled through the case and had no primer. It came in cartons of 50 cartridges. It was used to safely teach loading and unloading the M1 carbine to recruits.
- Cartridge, caliber .30, carbine, ball, high pressure test, M18 [Tin-plated cartridge case] - This cartridge used the same spitzer-type bullet as the .30-06 Ball M2. It came in cartons of 50 rounds. First introduced in 1942, it was used to proof the carbine and its components at the factory or an army arsenal. The tinned case was adopted in 1943 to prevent its confusion with standard Ball ammunition.
- Cartridge, caliber .30, carbine, tracer, M27 [Red tipped bullet] - It came in cartons of 50 cartridges.
- 7,62mm Kurz [German > "Short"] - The NATO designation for .30 Carbine ball M1 ammunition. It was first issued to the West German police forces and the auxiliaries in the Western Occupied Zones of Berlin, explaining its German-language designation. France used ammunition with this designation in Algeria.

As a parent case
The .30 Carbine was the basis for Melvin M. Johnson's .22 Spitfire (5.7x33mm), necking the .30 Carbine's case down to a .22 caliber bullet. It was designed to improve the range and stopping power of the M1 carbine. The Plainfield Machine Company (later taken over by Iver Johnson's Arms) sold a sporting rifle copy of the M1 carbine chambered for this cartridge but only about 500 were made.
