Whisper (cartridge Family)
The Whisper family of firearm cartridges is a group of wildcat cartridges developed in the early 1990s by J.D. Jones of 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 ba ...

45-70
The .45-70 rifle cartridge, also known as the .45-70 Government, was developed at the U.S. Army's Springfield Armory for use in the Springfield Model 1873, which is known to collectors as the "Trapdoor Springfield." The new cartridge was a replacement for the stop-gap .50-70 Government cartridge, which had been adopted in 1866, one year after the end of the American Civil War. Nomenclature The new cartridge was completely identified as the ''.45-70-405'', but was also referred to as the ".45 Government" cartridge in commercial catalogs. The nomenclature of the time was based on three properties of the cartridge: * .45: nominal diameter of bullet, measured in decimal inches, i.e., 0.458 inches (11.63 mm); * 70: weight of black powder, measured in grains, i.e., 70 grains (4.56 g); * 405: weight of lead bullet, measured in grains, i.e., 405 grains (26.38 g). The minimum acceptable accuracy of the .45-70 from the 1873 Springfield was approximately at , however, the heavy, slo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
30 Mauser
3 (three) is a number, numeral and digit. It is the natural number following 2 and preceding 4, and is the smallest odd prime number and the only prime preceding a square number. It has religious or cultural significance in many societies. Evolution of the Arabic digit The use of three lines to denote the number 3 occurred in many writing systems, including some (like Roman and Chinese numerals) that are still in use. That was also the original representation of 3 in the Brahmic (Indian) numerical notation, its earliest forms aligned vertically. However, during the Gupta Empire the sign was modified by the addition of a curve on each line. The Nāgarī script rotated the lines clockwise, so they appeared horizontally, and ended each line with a short downward stroke on the right. In cursive script, the three strokes were eventually connected to form a glyph resembling a with an additional stroke at the bottom: ३. The Indian digits spread to the Caliphate in the 9th ...

7mm-08 Remington
The 7mm-08 Remington is a rifle cartridge that is almost a direct copy of a wildcat cartridge developed around 1958 known as the 7mm/308. As these names would suggest, it is the .308 Winchester case necked down to accept 7 mm (.284) bullets with a small increase in case length. Of cartridges based upon the .308, it is the second most popular behind only the .243 Winchester. However, the .308 is more popular than both. In 1980, the Remington Arms company popularized the cartridge by applying its own name and offering it as a chambering for their Model 788 and Model 700 rifles, along with a limited-run series within their Model 7600 pump-action rifles during the early 2000s. Handloading The popularity of the cartridge means there is a fairly wide selection of factory loads, making it a choice even for those who do not handload. Bullets weighing from 100 to 195 grains are available. Bullets in the 120 to 160-grain range will suit most hunting applications while long-range sho ...

308 Winchester
The .308 Winchester is a smokeless powder rimless bottlenecked rifle cartridge widely used for hunting, target shooting, police, military, and personal protection applications globally. It is similar but not identical to the 7.62×51mm NATO cartridge. History During the 1940s, the .300 Savage became the basis for experiments on behalf of the U.S. military that resulted in the development of the T65 series of experimental cartridges. The original experimental case design by the Frankford Arsenal was designated the T65 and was similar to the .300 Savage case, but with less taper. The experimental cases were made from standard .30-06 Springfield cases which gave a little less capacity than standard .300 Savage cases because the Frankford Arsenal cases had slightly thicker case walls. The later T65 iterations were lengthened compared to the original T65 case and provided a ballistic performance roughly equal to the U.S. military .30-06 Springfield service cartridge.

223 Remington
The .223 Remington (designated as the 223 Remington by the SAAMI and 223 Rem by the CIP) is a rimless, bottlenecked rifle cartridge. It was developed in 1957 by Remington Arms and Fairchild Industries for the U.S. Continental Army Command of the United States Army as part of a project to create a small-caliber, high-velocity firearm. The .223 Remington is considered one of the most popular common-use cartridges and is currently used by a wide range of semi-automatic and manual-action rifles as well as handguns. History The development of the cartridge, which eventually became the .223 Remington, was linked to the development of a new lightweight combat rifle. The cartridge and rifle were developed by Fairchild Industries, Remington Arms, and several engineers working toward a goal developed by U.S. Continental Army Command (CONARC). Development began in 1957. A project to create a small-caliber, high-velocity (SCHV) firearm was created. Eugene Stoner of ArmaLite was al ...

338 Lapua
The .338 Lapua Magnum (8.6×70 mm or 8.58×70 mm) is a rimless, bottlenecked, centerfire rifle cartridge. It was developed during the 1980s as a high-powered, long-range cartridge for military snipers. It was used in the War in Afghanistan and the Iraq War. As a result of this, it has become widely available. The loaded .338 cartridge is in diameter (rim) and long. It can penetrate better-than-standard military body armor at ranges of up to , and has a maximum effective range of about with C.I.P. conforming ammunition at sea level conditions. Muzzle velocity is dependent on barrel length, seating depth, and powder charge, and varies from for commercial loads with bullets, which corresponds to about of muzzle energy.

510 Whisper
The .510 Whisper 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 (13×47 mm) is the second of two 1/2 inch caliber 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 0.4 inch (10 mm) 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 500 yards. This gives it more downrange energy at that distance than traditional .30 caliber rounds such as the .308 Winchester and .300 Winchester Magnum.
