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"

I-beam or a T-beam; or for attachment to another object, as the flange on the end of a pipe, steam cylinder, etc., or on the lens mount of a camera; or for a flange of a rail car or tram wheel. Thus flanged wheels are wheels with a flange on one side to keep the wheels from running off the rails. The term "flange" is also used for a kind of tool used to form flanges

The .38 ACP (Automatic Colt Pistol) also known as the .38 Auto was introduced at the turn of the 20th century for the John Browning-designed Colt M1900. It was first used in Colt's Model 1897 prototype, which he did not produce. The metric designation for the round is 9×23 mm SR (Semi Rimmed) (not to be confused with the later 9×23mm Winchester).Contents1 History 2 .38 Super 3 Firearms chambered for .38 ACP 4 See also 5 References 6 External linksHistory[edit] Initial loadings of this cartridge were quite powerful. Reported ballistics for the first commercial loads were a 130-grain bullet at 1,260 ft/s (380 m/s), and some experimental loads ran as high as 1,350 ft/s (410 m/s).[2] However, these ballistics proved too violent for the Colt Model 1900 pistol, and velocities were soon lowered to below 1,200 ft/s (370 m/s). Subsequent commercial loadings varied considerably in power

A combination gun is a hunting firearm that comprises at least one rifled barrel and one smoothbore barrel, that is typically used with shot or some types of shotgun slug. Most have been break-action guns, although there have been other designs as well. Combination guns using one rifled and one smoothbore barrel usually are in an over and under configuration. Side-by-side versions are referred to as cape guns. A drilling (German for "triplet") is a combination gun that has three barrels. A vierling (German for "quadruplet") has four barrels. Combination guns generally use rimmed cartridges, as rimless cartridges are more difficult to extract from a break-action weapon.Contents1 Use 2 Firing mechanisms 3 Layouts3.1 Combination guns 3.2 Cape guns 3.3 Drillings 3.4 Vierlings4 See also 5 Notes 6 ReferencesUse[edit] Combination guns have a long history in Europe, Africa, and Asia, dating back to the early days of cartridge firearms.

A magazine is an ammunition storage and feeding device within or attached to a repeating firearm. Magazines can be removable (detachable) or integral (internal/fixed) to the firearm. The magazine functions by moving the cartridges stored within it into a position where they may be loaded into the barrel chamber by the action of the firearm. The detachable magazine is often colloquially referred to as a clip, although this is technically inaccurate.[1][2][3] Magazines come in many shapes and sizes, from tubular magazines on lever-action rifles that hold only a few rounds,[not in citation given] to detachable box and drum magazines for automatic rifles and machine guns that can hold more than one hundred rounds

The .22 Hornet
.22 Hornet or 5.6×35mmR[2] is a varmint, small-game, predator, and competition centerfire rifle cartridge commercially introduced in 1930. It is considerably more powerful than the .22 WMR
.22 WMR and the .17 HMR, achieving higher velocity with a bullet twice the weight of the .17 HMR
.17 HMR bullet. The Hornet also differs very significantly from these in that it is not a rimfire but a centerfire cartridge. This makes it handloadable and reloadable, and thus much more versatile. It was the smallest commercially available .22 caliber centerfire cartridge until the introduction of the FN 5.7×28mm. The .22 Hornet
.22 Hornet fills the gap between such popular varmint/predator cartridges as the .22 WMR

A firearm is a portable gun (a barreled ranged weapon) that inflicts damage on targets by launching one or more projectiles driven by rapidly expanding high-pressure gas produced by exothermic combustion (deflagration) of propellant within an ammunition cartridge.[1][2][3] If gas pressurization is not achieved via propellant combustion but through mechanical gas compression, then the gun is technically an air gun, not a firearm.[4] The first primitive firearms originated in 10th-century China when bamboo tubes containing gunpowder and pellet projectiles were mounted on spears into the one-person-portable fire lance,[5], which was later used as a shock weapon to good effect in the Siege of De'an. In 13th century, the Chinese invented the metal-barrelled hand cannon, widely considered to be the true ancestor of all firearms. The technology gradually spread through the rest of East Asia, South Asia, the Middle East, and Europe

The system of imperial units or the imperial system (also known as British Imperial[1] or Exchequer Standards of 1825) is the system of units first defined in the British Weights and Measures Act of 1824, which was later refined and reduced. The Imperial units
Imperial units replaced the Winchester Standards, which were in effect from 1588 to 1825.[2] The system came into official use across the British Empire. By the late 20th century, most nations of the former empire had officially adopted the metric system as their main system of measurement, although some imperial units are still used in the United Kingdom, Canada
