.204 Ruger
The .204 Ruger / 5.2x47mm is a centerfire rifle cartridge developed by Hornady and Ruger. At the time of its introduction in 2004, the .204 Ruger was the second-highest velocity commercially produced ammunition and the only centerfire cartridge produced commercially for bullets of .204 inch/5 mm caliber. Characteristics The .204 Ruger was developed from the .222 Remington Magnum, which has the second-largest case capacity in the family that began with the .222 Remington. Only the European 5.6×50mm Magnum is larger, which itself is a lengthened version of the .222 Remington Magnum. The .222 Remington Magnum provides about 5% more usable (below the neck) case capacity than the most popular member of the family, the NATO 5.56×45mm (.223 Remington). To make the .204 Ruger, the .222 Remington Magnum case was necked down to .204 inches (5 mm) and its shoulder moved forward and angle increased to 30 degrees. Bullets available in .204 caliber range from 24 to 55 grains (1. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Handloading
Handloading, or reloading, is the practice of making firearm cartridges by manually assembling the individual components ( metallic/ polymer case, primer, propellant and projectile), rather than purchasing mass-assembled, factory-loaded commercial ammunition. (It should not be confused with the reloading of a firearm ''with'' cartridges, such as by swapping detachable magazines, or using a stripper clip or speedloader to quickly insert new cartridges into a magazine.) The term ''handloading'' is the more general term, and refers generically to the manual assembly of ammunition cartridges. ''Reloading'' refers more specifically to handloading using previously fired cases and shotshells. 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 or shells — new components are generally ready to load straight out of the box, w ...

17 HMR
.17 Hornady Magnum Rimfire, commonly known as the .17 HMR, is a rimfire rifle cartridge developed by Hornady in 2002. It was developed by necking down a .22 Winchester Magnum Rimfire case to take a .17 caliber (4.5mm) projectile. Commonly loaded with a 17 grain (1.1 g) projectile, it can deliver muzzle velocities in excess of 775 m/s (2,650 ft/s). Development The .17 HMR round is similar to rounds developed by dedicated rimfire wildcatters who worked to create a rimfire cartridge with an exceptionally flat trajectory. These wildcatters were seeking to match the ballistics of the obsolete 5mm Remington Rimfire Magnum, which was made from 1970 to 1974, and was to that point the fastest rimfire cartridge ever produced. With 5 mm diameter barrels and bullets being virtually unavailable at the time (the 5mm RMR was the last commercial 5 mm round until the 2004 release of the centerfire .204 Ruger), the commercially available .17 caliber became their bullet of choice. The .22 W ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
17 Remington
The .17 Remington / 4.4x45mm is a rifle cartridge introduced in 1971 by Remington Arms Company for their Remington 700, model 700 rifles. Overview The .17 Remington is based on the .223 Remington case necked down to .172 in (4.37 mm), with the shoulder moved back. Extremely high initial velocity (over 4,000 feet per second, ft/s 1,200 m/s), flat trajectory and very low recoil are the .17 Remington's primary attributes. It has a maximum effective projectile, range of about on prairie dog-sized animals, but the small bullet's poor ballistic coefficients and sectional densities mean it is highly susceptible to crosswinds at such distances. The smaller .172 bullet typically has a much lower ballistic coefficient than other typical varmint calibers, such as that of the .223 Remington. Because of this, the .172 bullet loses velocity slightly sooner and is more sensitive to wind; but by no means does this render the cartridge useless. The tiny entrance wound and usual lack o ...

22-250 Remington
The symbol , known in Unicode as hyphen-minus, is the form of hyphen most commonly used in digital documents. On most keyboards, it is the only character that resembles a minus sign or a dash, so it is also used for these. The name ''hyphen-minus'' derives from the original ASCII standard, where it was called ''hyphen (minus)''. The character is referred to as a ''hyphen'', a ''minus sign'', or a ''dash'' according to the context where it is being used. Description In early typewriters and character encodings, a single key/code was almost always used for hyphen, minus, various dashes, and strikethrough, since they all have a similar appearance. The current Unicode Standard specifies distinct characters for several different dashes, an unambiguous minus sign (sometimes called the ''Unicode minus'') at code point U+2212, an unambiguous hyphen (sometimes called the ''Unicode hyphen'') at U+2010, the hyphen-minus at U+002D and a variety of other hyphen symbols for various uses.

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 ...

Benchrest Shooting
Benchrest shooting is a shooting sport discipline in which high-precision rifles are rested on a table or benchrather than being carried in the shooter's handswhile shooting at paper or steel targets, hence the name "benchrest". Both the forearm and buttstock of such a rifle are usually fully supported by bean bags, a bipod/ monopod (front/rear) combination, and/or a specially designed fixture device called shooting rest (which may be one- or two-piece depending on competition rules), so that the gun can remain stably pointing at the target without needing to be held by someone. When shooting, the shooter simply sits/stands comfortably behind the table/bench, operates the action and pulls the trigger, without needing to worry about carrying any weight of the gun. This is in contrast to other shooting disciplines, where the shooter has to bear at least part of the gun's weight while holding it steady to aim, even when using support devices such as bipods, tripods or sho ...

Minute Of Arc
A minute of arc, arcminute (abbreviated as arcmin), arc minute, or minute arc, denoted by the symbol , is a unit of angular measurement equal to of a degree. Since one degree is of a turn, or complete rotation, one arcminute is of a turn. The nautical mile (nmi) was originally defined as the arc length of a minute of latitude on a spherical Earth, so the actual Earth's circumference is very near . A minute of arc is of a radian. A second of arc, arcsecond (abbreviated as arcsec), or arc second, denoted by the symbol , is a unit of angular measurement equal to of a minute of arc, of a degree, of a turn, and (about ) of a radian. These units originated in Babylonian astronomy as sexagesimal (base 60) subdivisions of the degree; they are used in fields that involve very small angles, such as astronomy, optometry, ophthalmology, optics, navigation, land surveying, and marksmanship. To express even smaller angles, standard SI prefixes can be employed; the milliar ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Single Shot
In firearm designs, the term single-shot refers to guns that can hold only a single round of ammunition inside and thus must be reloaded manually after every shot. Compared to multi-shot repeating firearms ("repeaters"), single-shot designs have no moving parts other than the trigger, hammer/ firing pin or frizzen, and therefore do not need a sizable receiver behind the barrel to accommodate a moving action, making them far less complex and more robust than revolvers or magazine/ belt-fed firearms, but also with much slower rates of fire. The history of firearms began with muzzleloading single-shot firearms such as the hand cannon and arquebus, then multi-barreled designs such as the derringer appeared, and eventually many centuries passed before breechloading repeating firearms became commonplace. Although largely disappeared from military usage due to insufficient firepower, single-shot firearms are still produced by many manufacturers in both muzzleloading and ...

Ruger M77
The Ruger M77 is a bolt-action rifle produced by Sturm, Ruger & Co. It was designed by Jim Sullivan during his three years with Ruger. It was designed primarily as a hunting rifle featuring a traditional Mauser K98-style two-lugged bolt with a claw extractor. History Ruger's first bolt action rifle was introduced to the U.S. market back in 1968 after some years of design and innovation led by Jim Sullivan and influenced Bill Ruger himself, who hired Sullivan in 1965 primarily to develop the rifle. Investment casting was used to save on costs. Ruger M77's popularity rose fast due to features such as the Mauser type claw extractor that filled a gap in the market that occurred in 1964 when Winchester discontinued the controlled round feed version of the Model 70 in order to compete with the recently introduced Remington 700, as well as for the writings of the late Jack O'Connor favoring the rifle.

Bolt Action
Bolt action is a type of manual firearm action that is operated by ''directly'' manipulating the turn-bolt via a bolt handle, most commonly placed on the right-hand side of the firearm (as most users are right-handed). The majority of bolt-action firearms are rifles, but there are also some variants of shotguns and handguns that are bolt-action. Bolt action firearms are generally repeating firearms, but many single-shot designs are available particularly in shooting sports where single-shot firearms are mandated, such as most Olympic and ISSF rifle disciplines. From the late 19th century all the way through both World Wars, bolt action rifles were the standard infantry service weapons for most of the world's military forces, with the exception of the United States Armed Forces, who used the M1 Garand Semi-automatic rifle. In modern military and law enforcement after the Second World War, bolt-action firearms have been largely replaced by semi-automatic and selec ...
