.510 Whisper
The .510 Whisper (13×47mm) is a subsonic rifle cartridge developed by SSK Industries for use in suppressed rifles. It is capable of firing a .51 caliber bullet weighing at roughly . Overview The .510 Whisper (13×47mm) is the second of two rounds developed by J. D. Jones with a specific focus on the Thumper concept and subsonic use. Based on the .416 Rigby case, it is a non-belted and bottlenecked cartridge. Earlier J. D. Jones had already developed the similar .500 Whisper round, which has a roughly longer belted bottlenecked case based on the .378 Weatherby Magnum. Despite the large bullet, this round is very quiet when using a suppressor due to the subsonic nature of the cartridge. When used with a very high ballistic coefficient bullet, the round only loses about out to over . This gives it more downrange energy at that distance than traditional .30 caliber rounds such as the .308 Winchester and .300 Winchester Magnum.

Rifle
A rifle is a long gun, long-barreled firearm designed for accurate shooting and higher stopping power, with a gun barrel, barrel that has a helical or spiralling pattern of grooves (rifling) cut into the bore wall. In keeping with their focus on accuracy, rifles are typically designed to be held with both hands and braced firmly against the shooter's shoulder via a buttstock for stability during shooting. Rifles are used in warfare, law enforcement, hunting and shooting sports, target shooting sports. The invention of rifling separated such firearms from the earlier smoothbore weapons (e.g., arquebuses, muskets, and other long guns), greatly elevating their accuracy and general effectiveness. The raised areas of a barrel's rifling are called ''lands''; they make contact with and exert torque on the projectile as it moves down the bore, imparting a spin. When the projectile leaves the barrel, this spin persists and lends gyroscopic stability to the projectile due to conservatio ...

The .300 Win Mag remains the most popular . ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Pistol And Rifle Cartridges
A pistol is a type of handgun, characterised by a barrel with an integral chamber. The word "pistol" derives from the Middle French ''pistolet'' (), meaning a small gun or knife, and first appeared in the English language when early handguns were produced in Europe. In colloquial usage, the word "pistol" is often used as a generic term 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. The older single-shot and lever-action pistols are now rarely seen and used primarily for nostalgic hunting and historical reenactment. Fully-automatic machine pistols are uncommon in civilian usage because of their generally poor recoil-controllability (due to the lack of a buttstock) and strict laws and regulations governing their manufactur ...

Whisper Family Of Firearm Cartridges
The Whisper family of firearm cartridges is a group of wildcat cartridges developed in the early 1990s by J.D. Jones at SSK Industries. The Whisper family was developed as a line of accurate, multi-purpose cartridges using relatively heavy rifle bullets for a given caliber in subsonic loads. The intention was to create an extremely accurate cartridge family for military, police, competition and specialized hunting markets that could also be easily sound suppressed. While all cartridges in the Whisper family must be capable of accuracy using subsonic loads, most of the smaller caliber cartridges of the family (.308" and under) are also capable of being loaded to supersonic velocities using relatively lightweight bullets for their caliber, increasing their utility. Subsonic cartridges A subsonic cartridge is designed to fire its bullets at velocities slower than the speed of sound (1128 ft/s at 70 °F) to avoid the sonic crack caused by the bullet breaking the sound ...

Thompson Center Arms
Thompson/Center Arms is an American firearms company based in Rochester, New Hampshire. 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 Contende ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
SAKO
Sako Limited (natively ) is a Finnish firearm and ammunition manufacturer located in Riihimäki, Tavastia Proper in southern Finland. It also has owned the Tikka brand of bolt-action rifles since 1983, and is now owned by the Italian firearm holding company Beretta Holding. The name Sako comes from the company's former name (). History In 1919, two years after Finland declared independence from the Russian Empire, the Suojeluskuntain Yliesikunnan Asepaja (Civil Guard Supreme Staff Gun Works) opened in a former Helsinki brewery to repair private arms and recondition Russian military rifles for Finnish service. The rifle repair shop became financially independent of the civil guard in 1921. The Suojeluskuntain Yliesikunnan Asepaja moved from Helsinki to an ammunition factory in Riihimäki on 1 June 1927, and reorganized as SAKO in the 1930s. Sako started exporting pistol cartridges to Sweden in the 1930s and continued manufacturing submachine gun cartridges through World War ...

Standard Deviation
In statistics, the standard deviation is a measure of the amount of variation of the values of a variable about its Expected value, mean. A low standard Deviation (statistics), deviation indicates that the values tend to be close to the mean (also called the expected value) of the set, while a high standard deviation indicates that the values are spread out over a wider range. The standard deviation is commonly used in the determination of what constitutes an outlier and what does not. Standard deviation may be abbreviated SD or std dev, and is most commonly represented in mathematical texts and equations by the lowercase Greek alphabet, Greek letter Sigma, σ (sigma), for the population standard deviation, or the Latin script, Latin letter ''s'', for the sample standard deviation. The standard deviation of a random variable, Sample (statistics), sample, statistical population, data set, or probability distribution is the square root of its variance.

Minute Of Angle
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 milliarcsec ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Sako TRG
The Sako TRG (short for Finnish: "", " Precision Rifle G-series") is a bolt-action sniper rifle line designed and manufactured by Finnish firearms manufacturer SAKO of Riihimäki. It is the successor to the SAKO TR-6 target rifle, and thus the letter ''G'' within the rifle's name is meant to represent number 7 (since G is the seventh letter in alphabetical order). The TRG-21 and TRG-22 (A1) are designed to fire standard .308 Winchester (7.62×51mm NATO) sized cartridges, while the TRG-41 and TRG-42 (A1) are designed to fire more powerful and dimensionally larger .300 Winchester Magnum (7.62×67mm) and .338 Lapua Magnum (8.6×70mm) cartridges. They are available with olive drab green, desert tan/coyote brown, dark earth or black stocks, and are also available with a folding stock. The TRG-62 A1 was added to the product range as the third and largest iteration, designed to fire the even more powerful and dimensionally larger .375 CheyTac (9.5×77mm) cartridge. The sniper r ...
