.30
The 7.62 mm caliber is a nominal caliber used for a number of different cartridges. Historically, this class of cartridge was commonly known as .30 caliber, the imperial unit and customary unit equivalent, and was most commonly used for indicating a class of full-power military main battle rifle (MBR) cartridges. The measurement equals 0.30 inches or three decimal lines, written ''.3″'' and read as ''three-line''. 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 , although Soviet weapons commonly use a bullet, as do older British (.303 British) and Japanese ( 7.7×58mm Arisaka) cartridges. Pistol cartridges in 7.62 mm caliber Many pistol cartridges are in this caliber; the most common are: * 7.62×25mm Tokarev, also known as 7.62 mm TT, is used in the Tokarev pistol, and many of the World War II Soviet submachine guns * 7.63×25mm Mauser ...

30-06 Springfield
The .30-06 Springfield cartridge (pronounced "thirty- aught-six" ), 7.62×63mm in metric notation, and called the .30 Gov't '06 by Winchester, was introduced to the United States Army in 1906 and later standardized; it remained in military use until the late 1970s. The ".30" refers to the caliber of the bullet in inches. The "06" refers to the year the cartridge was adopted, 1906. It replaced the .30-03, 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. It remains a very popular sporting round, with ammunition produced by all major manufacturers. History In the early-1890s, the U.S. military adopted the smokeless powder .30-40 Krag rimmed cartridge. The 1894 version of that cartridge used a round-nose bullet. Around 1901, the U.S. started developing an experimental ri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
303 British
The .303 British (designated as the 303 British by the C.I.P. and SAAMI) or 7.7×56mmR, is a calibre rimmed rifle cartridge. The .303 inch bore diameter is measured between rifling lands as is the common practice in Europe which follows the traditional black powder convention. It was first manufactured in Britain as a stop-gap black powder round put into service in December 1888 for the Lee–Metford rifle. From 1891 the cartridge used smokeless powder which had been the intention from the outset, but the decision on which smokeless powder to adopt had been delayed. It was the standard British and Commonwealth military cartridge for rifles and machine guns from 1889 until the 1950s when it was replaced by the 7.62×51mm NATO. Cartridge specifications The .303 British has 3.64 ml (56 grains H2O) cartridge case capacity. The pronounced tapering exterior shape of the case was designed to promote reliable case feeding and extraction in bolt-action rifles and machine guns ...

308 Winchester
The .308 Winchester is a smokeless powder rimless bottlenecked rifle cartridge widely used for hunting, target shooting, police, military, and personal protection applications globally. It is similar but not identical to the 7.62×51mm NATO cartridge. History During the 1940s, the .300 Savage became the basis for experiments on behalf of the U.S. military that resulted in the development of the T65 series of experimental cartridges. The original experimental case design by the Frankford Arsenal was designated the T65 and was similar to the .300 Savage case, but with less taper. The experimental cases were made from standard .30-06 Springfield cases which gave a little less capacity than standard .300 Savage cases because the Frankford Arsenal cases had slightly thicker case walls. The later T65 iterations were lengthened compared to the original T65 case and provided a ballistic performance roughly equal to the U.S. military .30-06 Springfield service cartridge. Over forty ye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
30 Carbine
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 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. (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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
M1 Carbine
The M1 carbine (formally the United States Carbine, Caliber .30, M1) is a lightweight semi-automatic carbine that was a standard firearm for the U.S. military during World War II, the Korean War and the Vietnam War. The M1 carbine was produced in several variants and was widely used by paramilitary and police forces around the world, and also became a popular civilian firearm after World War II. The M2 carbine is the selective-fire version of the M1 carbine, capable of firing in both semi-automatic and full-automatic. The M3 carbine was an M2 carbine with an active infrared scope system. Despite having a similar name and physical outward appearance, the M1 carbine is not a carbine version of the M1 Garand rifle. On July 1, 1925, the U.S. Army began using the current naming convention where the "M" is the designation for "Model" and the number represents the sequential development of equipment and weapons. Therefore, the "M1 carbine" was the first carbine developed under t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
300 AAC Blackout (7
The .300 AAC Blackout (designated as the 300 BLK by the SAAMI and 300 AAC Blackout by the C.I.P. or 300 AAC Blackout'' C.I.P. TDCC sheet 300 ACC Blackout/ref>), also known as 7.62×35mm, is an intermediate cartridge developed in the United States by Advanced Armament Corporation (AAC) for use in the M4 carbine. The cartridge yields increased performance in shorter barrels and effective subsonic performance for suppressor use when compared to 5.56mm NATO. The 300 AAC Blackout utilizes standard 5.56mm NATO magazines and components with the exception of the barrel. History While 5.56×45mm NATO has enjoyed widespread acceptance in military circles, the nature of the missions encountered by some special operations groups often demand a round that provides better performance than that available in the high-energy, standard velocity rounds, and subsonic performance greater than standard 9×19mm Parabellum (the ubiquitous pistol and submachine gun) round. To meet this demand, AAC dev ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cartridge (weaponry)
A cartridge or a round is a type of pre-assembled firearm ammunition packaging a projectile (bullet, shot, or slug), a propellant substance (usually either smokeless powder or black powder) and an ignition device ( primer) within a metallic, paper, or plastic case that is precisely made to fit within the barrel chamber of a breechloading gun, for the practical purpose of convenient transportation and handling during shooting. Although in popular usage the term "bullet" is often informally used to refer to a complete cartridge, it is correctly used only to refer to the projectile. Cartridges can be categorized by the type of their primers – a small charge of an impact- or electric-sensitive chemical mixture that is located: at the center of the case head (centerfire); inside the rim ( rimfire); inside the walls on the fold of the case base that is shaped like a cup (cupfire, now obsolete); in a sideways projection that is shaped like a pin (pinfire, now obsolete); or a ...

Caliber
In guns, particularly firearms, caliber (or calibre; sometimes abbreviated as "cal") is the specified nominal internal diameter of the gun barrel bore – regardless of how or where the bore is measured and whether the finished bore matches that specification. It is measured in inches or in millimeters. In the United States it is expressed in hundredths of an inch; in the United Kingdom in thousandths; and elsewhere in millimeters. For example, a "45 caliber" firearm has a barrel diameter of roughly . Barrel diameters can also be expressed using metric dimensions. For example, a "9 mm pistol" has a barrel diameter of about 9 millimeters. Since metric and US customary units do not convert evenly at this scale, metric conversions of caliber measured in decimal inches are typically approximations of the precise specifications in non-metric units, and vice versa. In a rifled barrel, the distance is measured between opposing lands or between opposing grooves; groove meas ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mosin–Nagant
The Mosin–Nagant is a five-shot, bolt-action, internal magazine–fed military rifle. Known officially as the 3-line rifle M1891 and informally in Russia and former Soviet Union as Mosin's rifle ( ru , винтовка Мосина, ISO 9: ), it is primarily found chambered for its original 7.62×54mmR cartridge. Developed from 1882 to 1891, it was used by the armed forces of the Russian Empire, the Soviet Union and various other states. It is one of the most mass-produced military bolt-action rifles in history, with over 37 million units produced since 1891. In spite of its age, it has been used in various conflicts around the world up to the present day. History Initial design and tests During the Russo-Ottoman War of 1877–1878, Russian troops armed mostly with Berdan single-shot rifles suffered heavy casualties against Turkish troops equipped with Winchester repeating rifles, particularly at the bloody Siege of Pleven. This showed Russian commanders the need to m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Lee–Metford
The Lee–Metford rifle (a.k.a. ''Magazine Lee–Metford'', abbreviated ''MLM'') was a bolt-action British army service rifle, combining James Paris Lee's rear-locking bolt system and detachable magazine with an innovative seven groove rifled barrel designed by William Ellis Metford. It replaced the Martini–Henry rifle in 1888, following nine years of development and trials, but remained in service for only a short time until replaced by the similar Lee–Enfield. Design Lee's bolt action mechanism was a great improvement over other designs of the day: - The rear-mounted lugs placed the operating handle much closer to the rifleman, over the trigger. This made it much quicker to operate than other, forward-mounted lug designs which forced the rifleman to move his hand forward to operate the bolt. It also enabled the rifleman to operate the trigger with his middle finger while still holding the bolt between thumb and index finger. - The bolt's distance of travel was identical ...

SVD (rifle)
The SVD (russian: Сна́йперская Винто́вка систе́мы Драгуно́ва образца́ 1963 года, lit=Sniper Rifle, System of Dragunov, Model of the Year 1963, translit=Snáyperskaya Vintóvka sistém'y Dragunóva obraz'tsá 1963 goda), GRAU index 6V1, is a semi-automatic marksman rifle chambered in the fully-powered 7.62×54mmR cartridge, developed in the Soviet Union. The SVD was designed to serve a squad support role to provide precise long-range engagement capabilities to ordinary troops following the Warsaw Pact adoption of the 7.62×39mm intermediate cartridge and assault rifles as standard infantry weapon systems. At the time, NATO used battle rifles chambered in 7.62×51mm NATO as standard infantry weapon systems and had not yet adopted an intermediate cartridge and assault rifle of their own, allowing them to outrange their Warsaw Pact counterparts. It was developed through 1958–1963 and selected as the winner of a contest that ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
327 Federal Magnum
The .327 Federal Magnum is a cartridge introduced by Federal Premium Ammunition and also sold by Sturm, Ruger & Co. It is intended to provide the power of a .357 Magnum in a six-shot, compact revolvers, whose cylinders would otherwise only hold five rounds. The .327 has also been used in full-sized revolvers with a capacity of seven rounds or more. Development Introduced by the Federal Cartridge company, now known as Federal Premium Ammunition, the .327 Federal Magnum was an attempt to improve on the .32 H&R Magnum introduced in 1984. Like the .32 H&R, the .327 Federal is a lengthened version of the original .32 S&W cartridge, which dates back to 1878. In 1896, the .32 S&W Long was introduced, which generated slightly higher velocities. The introduction of the .32 H&R increased pressures from 15,000 psi to 21,000 CUP, giving velocities of approximately . Based on the .32 H&R Magnum, with a 1/8-inch longer case, a strengthened web at the base of the case, thicker case walls, ...
