.255 Jeffery Rook
The .255 Jeffery Rook, also known as the .255 Jeffery Rook Rifle, is an obsolete small bore firearm Cartridge (firearms), cartridge. Overview The .255 Jeffery Rook is a Rim (firearms), rimmed Centerfire ammunition, centerfire cartridge. It was loaded with both black powder and smokeless powders, usually with a lead solid or hollowpoint bullet at a standard muzzle velocity of . The .255 Jeffery Rook was developed by W.J. Jeffery & Co and originally designed for use in rook rifles for hunting small game and target shooting. It gained an excellent reputation for accuracy and was widely used for target shooting before being superseded by the .22 Long Rifle as a miniature target round, and it was also chambered in some single-shot pistols. Percy Powell-Cotton, Major Percy Powell-Cotton carried a W.J. Jeffery & Co rook rifle chambered in .255 Jeffery Rook on a number of his expeditions stating it "is often better than the shot-gun for collecting specimens and providing for the pot. ...

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 rim, 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 cartridge in the chamber of the firearm, with the rim ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cartridge (firearms)
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); ...

Centerfire Ammunition
Two rounds of .357 Magnum, a centerfire cartridge; notice the circular primer in the center A centerfire cartridge is a firearm metallic cartridge whose primer is located at the center of the base of its casing (i.e. "case head"). 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. Centerfire cartridges have supplanted the rimfire variety in all but the smallest cartridge sizes. The majority of today's handguns, rifles, and shotguns use centerfire ammunition, with the exception of a few .17 caliber, .20 caliber, and .22 caliber handgun and rifle cartridges, small-bore shotgun shells (intended for pest control), and a handful of antique (and mostly obsolete) cartridges. History An early form of centerfire ammunition, without a percussion cap, was invented between 1808 and 1812 by Jean Samuel Pauly. This was also the first f ...

Black Powder
Gunpowder, also commonly known as black powder to distinguish it from modern smokeless powder, is the earliest known chemical explosive. It consists of a mixture of sulfur, carbon (in the form of charcoal) and potassium nitrate ( saltpeter). The sulfur and carbon act as fuels while the saltpeter is an oxidizer. Gunpowder has been widely used as a propellant in firearms, artillery, rocketry, and pyrotechnics, including use as a blasting agent for explosives in quarrying, mining, building pipelines and road building. Gunpowder is classified as a low explosive because of its relatively slow decomposition rate and consequently low brisance. Low explosives deflagrate (i.e., burn at subsonic speeds), whereas high explosives detonate, producing a supersonic shockwave. Ignition of gunpowder packed behind a projectile generates enough pressure to force the shot from the muzzle at high speed, but usually not enough force to rupture the gun barrel. It thus makes a good prop ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rook Rifle
The rook rifle, originally called the rook and rabbit rifle, is an obsolete English single-shot small calibre rifle intended for shooting small game, particularly rook shooting. Design The rook rifle was designed to be light enough to be carried for a walk in the country, accurate and powerful enough to take small game and usually elegant in balance, fit and finish. Almost always single shot, various actions were used including break-open actions, but the miniature Martini, a scaled-down version of the military Martini-Henry, was a favourite due to its strength and accuracy. The first rook rifles fired calibre bullets, although subsequently a number of cartridges were developed for this purpose ranging in calibre from and firing bullets at the usual black powder velocities of . History The rook rifle was developed in 1883 by the gun-makers Holland & Holland as a breech-loading equivalent of the muzzle-loading pea rifle. Holland & Holland made a particular specialty of p ...

22 Long Rifle
The .22 Long Rifle or simply .22 LR or 22 (metric designation: 5.6×15mmR) is a long-established variety of .22 caliber rimfire ammunition originating from the United States. It is used in a wide range of rifles, pistols, revolvers, smoothbore shotguns, and submachine guns. In terms of units sold it is by far the most common ammunition in the world today. Common uses include hunting and shooting sports. Ammunition produced in .22 Long Rifle is effective at short ranges, has little recoil, and is cheap to purchase, making it ideal for training. History American firearms manufacturer J. Stevens Arms & Tool Company introduced the .22 Long Rifle cartridge in 1887. The round owes its origin to the .22 BB Cap of 1845 and the .22 Short of 1857. It combined the case of the .22 Long of 1871 with a bullet, giving it a longer overall length, a higher muzzle velocity and superior performance as a hunting and target round, rendering the .22 Extra Long cartridges obsolete. The . ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
