7-30 Waters
The 7-30 Waters cartridge was originally a wildcat cartridge developed by author Ken Waters in 1976 to give better performance to lever-action rifle shooters than the parent .30-30 Winchester cartridge, by providing a higher velocity and flatter trajectory with a smaller, lighter bullet. By 1984, Winchester introduced a Model 94 rifle chambered for the 7-30 Waters, establishing it as a commercial cartridge. In 1986, Thompson/Center began chambering 10-inch, 14-inch, and 20-inch Contender barrels for the cartridge. Development A review of the 7-08 Rem. (a .308 Win. case necked down to 7 mm), explains the design of the cartridge with the following: There are two primary reasons a 7 mm recoils less than an comparably effective .30 cal. cartridge: To match the 7 mm's ballistic coefficient requires a significantly heavier .30 cal bullet; and to drive that heavier .30 cal bullet at similar velocities (for kinetic energy and wind resistance ("time-to-target")), requires more powder ...

Spitzer Bullet
The spitzer bullet (or spire point) is a pointed projectile that is primarily used in small-arms. The pointed nose shape, which was developed for military purposes in the late 19th and early 20th century, was a major design improvement compared to earlier rounder or flatter-tipped bullets because pointed nose shapes were less susceptible to external ballistic factors like drag. By adding a point, projectiles made for fully-powered and intermediate rifle cartridges, obtain a lower drag coefficient which makes them decelerate less rapidly. Lowering the drag coefficient leads to improved external ballistic behaviour. The development of spitzer bullets and long-range volley sights for service rifles changed military doctrines. Area targets at ranges up to could be subject to rifle fire. With improvements in machine guns at the turn of the 20th Century, the addition of clinometers meant that fixed machine gun squads could deliver plunging fire or indirect fire at more than ...

Pistol And Rifle Cartridges
A pistol is a handgun, more specifically one with the chamber integral to its gun barrel, though in common usage the two terms are often used interchangeably. The English word was introduced in , when early handguns were produced in Europe, and is derived from the Middle French ''pistolet'' (), meaning a small gun or knife. In colloquial usage, the word "pistol" is often used to describe any type of handgun, inclusive of revolvers (which have a single barrel and a separate cylinder housing multiple chambers) and the pocket-sized derringers (which are often multi-barrelled). The most common type of pistol used in the contemporary era is the semi-automatic pistol, while the older single-shot and lever action, manual repeating pistols are now rarely seen and used primarily for nostalgic hunting and historical reenactment, and the fully automatic machine pistols are uncommon in civilian usage due to generally poor recoil-controllability and strict gun laws, laws and regulations ...

Nosler
Nosler, Inc. is an American manufacturing company based in Bend, Oregon, known for producing ammunition and handloading components and specializing in high performance hollow point and soft point hunting bullets. The current companies also include subsidiaries Nosler Custom and Nosler Reloading. Nosler's contributions to shooting sports include both polymer-tipped bullet designs and new manufacturing techniques used in their production. Early history John Amos Nosler was born on April 4, 1913 in Brawley, California. While hunting moose in British Columbia in 1946, the bullets he was using failed to penetrate deeply enough to reach vital organs and kill the animal quickly.Aaron Carter "John A. Nosler" ''American Rifleman'' January 2011 pp. 38–39 At the time, most jacketed bullets employed a single copper alloy envelope (the jacket) around a single lead alloy core. The jacket on most military bullets was closed in front and opened at the base. These full metal jacket ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Varmint Hunting
Varmint hunting or varminting is the practice of hunting vermin — generally small/medium-sized wild mammals or birds — as a means of pest control, rather than as games for food or trophy. The targeted animals are culled because they are considered economically harmful pests to agricultural crops, livestocks or properties; pathogen-carrying hosts/vectors that transmit cross-species/zoonotic diseases; or for population control as a mean of protecting other vulnerable species and ecosystems. The term "varminter" may refer to a ''varmint hunter'', or describe the hunting equipments (such as a varmint rifle) either specifically designed or coincidentally suitable for the practice of varmint hunting. Varmint hunters may hunt to exterminate a nuisance animal from their own property, to collect a bounty offered by another landowner or the government, or simply as a hobby. Targets of varmint hunting The term ''varmint'' is a US colloquial term for ''vermin'', though it refers ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metallic Silhouette
Metallic silhouette shooting is a group of target shooting disciplines that involves shooting at steel targets representing game animals at varying distances, seeking to knock the metal target over. Metallic silhouette is shot with large bore rifles fired freehand without support out to 500 meters, and with large bore handguns from the prone position with only body support out to 200 meters. Competitions are also held with airguns and black-powder firearms. A related genre is shot with bow and arrow, the metal targets being replaced with cardboard or foam. The targets used are rams, turkeys, pigs, and chickens, which are cut to different scales and set at certain distances from the shooter depending on the specific discipline. History Metallic silhouette is descended from an old Mexican sport, dating back to the early 1900s, wherein live game animals were staked out at varying distances as targets. By 1948, metal cutouts of the animals were used instead of live animals, birthing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Handgun Hunting
Handgun hunting is a form of hunting primarily done with specialized handguns that have long barrels and mounted scopes (optical aiming devices). Even the largest animals, such as elephants, can be killed with modern hunting handguns, although most handgun hunters only use handguns when hunting medium-sized game like deer and wild hogs. The .44 Magnum, developed in 1955, was the beginning of handgun hunting for mainstream hunters. Handgun hunters consider their activity more 'sporting' than using rifles. The comparatively short sight radius of a handgun and typically less powerful ammunition than used with rifles, means that any handgun hunter must stalk closer to the prey in order to kill the animal humanely, giving said animal more chance of detecting and avoiding the hunter. Most hunting handguns are either single-shot pistols, single-action revolvers, or double-action revolvers. Handgun hunting differs from rifle or shotgun hunting because a significant amount of shootin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Handloading
Handloading, or reloading, is the practice of making firearm cartridges by assembling the individual components (case, primer, propellant, and projectile), rather than purchasing mass-assembled, factory-loaded ammunition. The term ''handloading'' is the more general term, and refers generically to the manual assembly of ammunition. ''Reloading'' refers more specifically to handloading using previously fired cases and shells. The terms are often used interchangeably however, as the techniques are largely the same, whether the handloader is using new or recycled components. The differences lie in the initial preparation of cases and shells; new components are generally ready to load, while previously fired components often need additional procedures, such as cleaning, removal of expended primers, or the reshaping and resizing of brass cases. Reasons for handloading Economy, increased performance and accuracy, commercial ammunition shortages, and hobby interests are all ...

Thompson Center Arms
Thompson/Center Arms was an American firearms company based in Springfield, Massachusetts. The company was best known for its line of interchangeable-barrel, single-shot pistols and rifles. Thompson/Center also manufactures muzzle-loading rifles and was credited with creating the resurgence of their use in the 1970s. History In the 1960s, Warren Center developed an unusual break-action, single-shot pistol in his basement workshop that later became known as the Contender. Meanwhile, the K.W. Thompson Tool Company had been searching for a product to manufacture year-round. In 1965, Warren Center joined the K.W. Thompson Tool Company, and together, they announced Warren Center's Contender pistol in 1967. Although it sold for more than comparable hunting revolvers, the flexibility of being able to shoot multiple calibers by simply changing out the barrel and sights and its higher accuracy soon made it popular with handgun hunters. As K.W. Thompson Tool began marketing Center's Conte ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hornady Manufacturing Company
Hornady Manufacturing Company is an American manufacturer of ammunition cartridges, components and handloading equipments, based in Grand Island, Nebraska. History The company is currently run by Joyce Hornady's son, Steve Hornady, who took over after his father's death in a plane crash on January 15, 1981. The Piper Aztec, with Hornady at the controls flying in heavy fog, crashed into Lake Pontchartrain while on final approach to New Orleans Lakefront Airport. Pacific Tool Company Steve Hornady worked for Pacific Tool Company from 1960 to 1971, from the time the company moved from California to Nebraska until Pacific Tool was bought by Hornady. Pacific's DL-366 was their final progressive press and Hornady's first, and it is still manufactured by Hornady as the 366 Auto.

External Ballistics
External ballistics or exterior ballistics is the part of ballistics that deals with the behavior of a projectile in flight. The projectile may be powered or un-powered, guided or unguided, spin or fin stabilized, flying through an atmosphere or in the vacuum of space, but most certainly flying under the influence of a gravitational field. Gun-launched projectiles may be unpowered, deriving all their velocity from the propellant's ignition until the projectile exits the gun barrel. However, exterior ballistics analysis also deals with the trajectories of rocket-assisted gun-launched projectiles and gun-launched rockets; and rockets that acquire all their trajectory velocity from the interior ballistics of their on-board propulsion system, either a rocket motor or air-breathing engine, both during their boost phase and after motor burnout. External ballistics is also concerned with the free-flight of other projectiles, such as balls, arrows etc. Forces acting on the projectile W ...

Wildcat Cartridge
A wildcat cartridge, often shortened to wildcat, is a custom cartridge for which ammunition and/or firearms are not mass-produced. These cartridges are often created in order to optimize a certain performance characteristic (such as the power, size, or efficiency) of an existing commercial cartridge. Developing and using wildcat cartridges does not generally serve a purpose in military or law enforcement; it is more a hobby for serious 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. Barrels for the caliber are originally manufactured by gunsmiths specializing in barrel making. Ge ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
