In the cartridge's name, ".30" refers to the nominal caliber of the bullet in inches; "06" refers to the year the cartridge was adopted, 1906. It replaced the .30-03 Springfield, 6mm Lee Navy, and .30-40 Krag cartridges. The .30-06 remained the U.S. Army's primary rifle and machine gun cartridge for nearly 50 years before being replaced by the 7.62×51mm NATO and 5.56×45mm NATO, both of which remain in current U.S. and NATO service. The cartridge remains a very popular sporting round, with ammunition produced by all major manufacturers.

1948 Arab–Israeli War
The 1948 Arab–Israeli War, also known as the First Arab–Israeli War, followed the 1947–1948 civil war in Mandatory Palestine, civil war in Mandatory Palestine as the second and final stage of the 1948 Palestine war.

Rifle
A rifle is a long gun, long-barreled firearm designed for accurate shooting and higher stopping power, with a gun barrel, barrel that has a helical or spiralling pattern of grooves (rifling) cut into the bore wall. In keeping with their focus on accuracy, rifles are typically designed to be held with both hands and braced firmly against the shooter's shoulder via a buttstock for stability during shooting. Rifles are used in warfare, law enforcement, hunting and shooting sports, target shooting sports. The invention of rifling separated such firearms from the earlier smoothbore weapons (e.g., arquebuses, muskets, and other long guns), greatly elevating their accuracy and general effectiveness. The raised areas of a barrel's rifling are called ''lands''; they make contact with and exert torque on the projectile as it moves down the bore, imparting a spin. When the projectile leaves the barrel, this spin persists and lends gyroscopic stability to the projectile due to conservatio ...

Tapering (firearms)
In firearms,Tapering refers to components that narrow down, similar to that of a conical fashion hence the name taper. Barrels In barrels, this centralises mass to the operator. Not only to reduce weight from the muzzle but also to increase accuracy/ acquisition and stabilise the balance handling of the weapon. Also the fact that chamber pressures are higher at the rear of the barrel. Rifling In rifling, a Tapered bore/Conical bore is where the caliber narrows off to increase velocity of the round. Cartridges In cartridges, this usually helps in chambering/unloading the weapon. This differs than shouldering/bottleneckingCartridges and Firearm Identification By Robert E. Walker.

Rim (firearms)
A rim is an external flange that is machined, cast, molded, stamped, or pressed around the bottom of a firearms cartridge. Thus, rimmed cartridges are sometimes called "flanged" cartridges. Almost all cartridges feature an extractor or headspacing rim, in spite of the fact that some cartridges are known as "rimless cartridges". The rim may serve a number of purposes, including providing a lip for the extractor to engage, and sometimes serving to headspace the cartridge. Types There are various types of firearms rims in use in modern ammunition. The main types are categorized as rimmed, rimless, semi-rimmed, rebated, and belted. These describe the size of the rim in relation to the base of the case. Rimmed The rimmed cartridge, sometimes called flanged cartridge, is the oldest of the types and has a rim that is significantly larger in diameter than the base of the cartridge. Rimmed cartridges use the rim to hold the (usually straight sided) cartridge in the chamber of th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
SAAMI
The Sporting Arms and Ammunition Manufacturers' Institute (SAAMI, pronounced "Sammy") is an association of American manufacturers of firearms, ammunition, and components. SAAMI is an accredited standards developer that publishes several American National Standards that provide safety, reliability, and interchangeability standards for commercial manufacturers of firearms, ammunition, and components. In addition, SAAMI publishes information on the safe and responsible transportation, storage, and use of those products. History The origins of SAAMI date back to World War I and the Society of American Manufacturers of Small Arms and Ammunition (SAMSAA). In 1913, the US War Department encouraged the firearms and ammunition industry to establish an organization to share new technology and establish common standards for small arms and ammunition. SAMSAA was officially formed in 1918, however became inactive by the early 1920s. By the mid-1920s, the United States was still ...

It was a military escalation of the Sino–Indian border dispute. Fighting occurred along India's border with China, in India's North-East Frontier Agency east of Bhutan, and in Aksai Chin west of Nepal. There had been a series of border skirmishes between the two countries after the 1959 Tibetan uprising, when India granted asylum to the Dalai Lama.
