In 1938, the Chief of Infantry requested that the Ordnance Department develop a "light rifle" or carbine, though the formal requirement for the weapon type was not approved until 1940. This led to a competition in 1941 by major U.S. firearm companies and designers. The prototypes for the carbine competition were chambered for a new cartridge, the .30 Carbine, a smaller and lighter .30 caliber (7.62 mm) round very different from the .30-06 in both design and performance. The .30 Carbine cartridge was intermediate in muzzle energy (ME) and muzzle velocity (MV). Essentially a rimless version of the obsolete .32 Winchester Self-Loading cartridge, the .30 Carbine had a round-nose 110 gr (7.1 g) bullet. From an 18 in (460 mm) barrel, the .30 Carbine cartridge produced a muzzle velocity of approximately 1,970 ft/s (600 m/s).
Winchester at first did not submit a carbine design, as it was occupied in developing the .30-06 Winchester M2 Military Rifle. The rifle originated as a design by Jonathan "Ed" Browning, brother of the famous firearm designer John Browning. A couple of months after Ed Browning's death in May 1939, Winchester hired David Marshall "Carbine" Williams who had begun work on a short-stroke gas piston design while serving a prison sentence at a North Carolina minimum-security work farm. Winchester, after Williams' release, had hired Williams on the strength of recommendations of firearms industry leaders, and hoped Williams would be able to complete various designs left unfinished by Ed Browning, including the Winchester .30-06 M2 rifle. Williams incorporated his short-stroke piston in the existing design. After the Marine Corps semi-automatic rifle trials in 1940, Browning's rear-locking tilting bolt design proved unreliable in sandy conditions. As a result, the rifle was redesigned to incorporate a Garand-style rotating bolt and operating rod, retaining Williams' short-stroke piston. By May 1941, Williams had shaved the M2 rifle prototype from about 9.5 lb (4.3 kg) to a mere 7.5 lb (3.4 kg).
这是维基百科上对于M1卡宾枪的一段描述，英文的哦。不是百度中文的。这是相关网址。http://en.wikipedia.org/wiki/M1_carbine
这真不是较真的问题，是很简单的时间点前后的逻辑问题。 |
