7.62×45mm
The 7.62×45mm (designated as the 7,62 × 45 by the C.I.P.) is a rimless bottlenecked intermediate rifle cartridge developed in Czechoslovakia. It is fired by the Czech Vz. 52 rifle, Vz. 52 light machine gun, and ZB-530 machine gun. The cartridge was later dropped from use when the Czech converted to the standard 7.62×39mm Warsaw Pact cartridge of the Soviet Union. Its muzzle velocity and muzzle energy are slightly higher than that of the 7.62×39mm cartridge, and is on par with the .30-30 Winchester cartridge, with equivalent projectiles. Cartridge dimensions The 7.62×45mm has a 2.79 mL (43.1 gr H2O) cartridge case capacity. The exterior shape of the case was designed to promote reliable case feeding and extraction in bolt-action and semi-automatic rifles and machine guns alike, under extreme conditions. 7.62×45mm maximum C.I.P. cartridge dimensions. All sizes in millimeters (mm). Americans would define the shoulder angle at alpha/2 ≈ 24.9 degrees. The com ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Intermediate Cartridge
An intermediate cartridge is a rifle/ carbine cartridge that has significantly greater power than a pistol cartridge but still has a reduced muzzle energy compared to fully powered cartridges (such as the .303 British, 7.62×54mmR, 7.65×53mm Mauser, 7.92×57mm Mauser, 7.7×58mm Arisaka, , or 7.62×51mm NATO), and therefore is regarded as being "intermediate" between traditional rifle and handgun cartridges. As their recoil is significantly reduced compared to full-power cartridges, fully automatic rifles firing intermediate cartridges are relatively easy to control. However, even though they are less powerful than a traditional full-power cartridge, the external ballistics are still sufficient for an effective range of , which covers most typical infantry engagement situations in modern warfare. This allowed for the development of the assault rifle, a type of versatile selective fire small arms that is lighter and more compact than traditional battle rifles that fire f ...

ZB-530
The ZB-53 was a Czechoslovak machine gun. A versatile weapon, it was used both as a squad support weapon, as a mounted machine gun for tanks and other armoured vehicles, and on fixed positions inside Czechoslovak border fortifications. Adopted before World War II by the armies of Czechoslovakia (as Těžký kulomet vz. 37, heavy machine gun model 37) and Romania, it was also license-built in the United Kingdom as the Besa machine gun. Following the German invasion of Czechoslovakia, large quantities of the weapon were captured by the Wehrmacht and used during the war under the designation of MG 37(t). History The ZB-53 was designed as a private venture by Václav Holek and Miroslav Rolčík of the Zbrojovka Brno works as a replacement for the Schwarzlose machine gun of World War I origin. Czechoslovakia purchased 500 for testing giving them the designation Vz.35 ("1935 Model"). Based on these tests some improvements were requested and the improved ZB-53 was adopted by the Czech ...

Unlike rimfire cartridges, the centerfire primer is typically a separate component seated into a recessed cavity (known as the ''primer pocket'') in the case head and is replaceable by reloading the cartridge. Centerfire cartridges have supplanted the rimfire cartridge, with the exception of a few small calibers.

Wildcat Cartridge
A wildcat cartridge, often shortened to wildcat, is a custom-made cartridge (weaponry), cartridge for which ammunition and/or firearms are not mass-produced. These cartridges are often created as experimental variants to optimize a certain ballistic performance characteristic (such as the power, size, or efficiency) of an existing commercial cartridge, or may merely be intended as novelty items. Developing and using wildcat cartridges does not generally serve a purpose in military or law enforcement; it is more a hobby for serious sport shooting, hunting, gunsmithing and handloading enthusiasts, particularly in the United States. There are potentially endless varieties of wildcat cartridge: one source of gunsmithing equipment has a library of over 6,000 different wildcat cartridges for which they produce equipment such as chamber reamers. Development of a wildcat Often, wildcats are commercially sold rounds that have been modified in some way to alter the cartridge's performance. ...

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 ...

300 Savage
The .300 Savage cartridge is a rimless, .30 caliber rifle cartridge developed by Savage Arms in 1920. It was designed to replace the less powerful .303 Savage in their popular Savage Model 1899 hammerless lever-action rifle, which they started to produce again as Model 99, as well as the new Savage Model 1920 bolt-action rifle. Despite having a short case in order to fit the original Model 99 magazine and a rather stumpy neck, the cartridge is capable of propelling a bullet at over with an effective range of over . Performance Pressure level for the .300 Savage is set by SAAMI at 46,000 CUP.Reloading data at Accurate Powder Official |
220 Swift
The .220 Swift (5.56×56mmSR) is a semi-rimmed rifle cartridge developed by Winchester and introduced in 1935 for small game and varmint hunting. It was the first factory-loaded rifle cartridge with a muzzle velocity of over . Description The velocity of the cartridge ranges from up to about . The Swift is a large-cased .224 caliber cartridge and bullet that was created for small game such as prairie dogs, groundhogs, marmots and other vermin (or "varmints" in the US). When introduced it was faster than its nearest varmint-hunting competitor, which was the .22 Hornet (also .224 caliber). It was found to be an extremely accurate cartridge as well. Due to its very high velocity its bullet drop allows precise sighting to ranges out to , and it is still considered an excellent cartridge for taking varmints by experienced Swift shooters. The original factory load from Winchester provided a bullet launched at . Handloaders could marginally improve on this but only at maxim ...

308 Winchester
The .308 Winchester is a smokeless powder Rim (firearms), rimless bottlenecked rifle Cartridge (firearms), 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 7.62×51mm NATO#Development, T65 series of experimental cartridges. The original experimental case design by the Frankford Arsenal was designated "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 walls. The later T65 iterations were lengthened compared to the original T65 case and provided a ballistic performance roughly equal to the U.S. mi ...
