.300 RUM
The .300 Remington Ultra Magnum, also known as the .300 Ultra Mag, 7.62×72mm or .300 RUM is a 7.62 mm (.308 inch) rifle cartridge introduced by Remington Arms in 1999. The .300 Remington Ultra Magnum is one of the largest commercially available .30 caliber magnums currently being produced. It is a beltless, rebated rim cartridge, capable of handling all large North American game, as well as long-range shooting. Among commercially produced .30-caliber rifle chamberings, the .300 Remington Ultra Magnum is second only to the .30-378 Weatherby Magnum in cartridge-case capacity. Origin & History In the early 1980s Aubrey White and Noburo Uno of North American Shooting Systems (NASS) based in British Columbia Canada began experimenting with the full length .404 Jeffery by reducing the taper and necking it down to various calibers such as 7 mm, .308, 311, 338, 9.3 mm and .375. These cartridges were known variously as the Canadian Magnum or the Imperial Magnums. Rifles ...

Remington Arms Company
Remington Arms Company, LLC was an American manufacturer of firearms and ammunition, now broken into two companies, each bearing the Remington name. The firearms manufacturer is ''Remington Arms''. The ammunition business is called ''Remington''. The company which was broken up was called Remington Outdoor Company. Sturm, Ruger & Co. purchased the Marlin Firearms division of the Remington Outdoor Company in 2020. Founded in 1816 by Eliphalet Remington (as E. Remington and Sons) in Ilion, New York, it was one of the oldest gun makers in the US and claimed to be the oldest factory in the US that still made its original product. The company was the largest rifle manufacturer in North America according to 2015 ATF statistics. The company developed or adopted more cartridges than any other gun maker or ammunition manufacturer in the world. History 19th century origins The Remington company was founded in 1816. Eliphalet Remington II (1793–1861) believed he could build ...

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 ...

This is a table of selected pistol/ submachine gun and rifle/ machine gun cartridges by common name. Data values are the highest found for the cartridge, and might not occur in the same load (e.g. the highest muzzle energy might not be in the same load as the highest muzzle velocity, since the bullet weights can differ between loads).

Overbore
Overbore cartridges are those with a relatively large case volume or case capacity, coupled with a relatively small diameter bullet. The case volume or case capacity and barrel bore area can be mathematically related to obtain a case volume to bore area ratio in metric or imperial units. = \frac where: * Volume_ = the cartridge case internal volume or case capacity (in ml or (for non-metric users) grains of water) * Area_ = barrel bore cross section area (in cm2 or in2) The higher the Oratio result, the more overbore a cartridge will be. As the ratio is expressed in units of length, relatively high Oratio is a good predictor of suitability for relatively long barreled guns. Oratio is also used to predict barrel life in cartridges of the same caliber, but not of different calibres, since the ratio is an extensive quantity that does not correlate to temperature or pressure (e.g. a .50 cal straight cartridge may have the same overbore as a highly necked down .17 cal cartridge).

Sporting Arms And Ammunition Manufacturers' Institute
The Sporting Arms and Ammunition Manufacturers' Institute (SAAMI, pronounced "Sammy") is an association of American manufacturers of firearms, ammunition, and components. SAAMI is an accredited standards developer that publishes several American National Standards that provide safety, reliability, and interchangeability standards for commercial manufacturers of firearms, ammunition, and components. In addition, SAAMI publishes information on the safe and responsible transportation, storage, and use of those products. History The origins of SAAMI date back to World War I and the Society of American Manufacturers of Small Arms and Ammunition (SAMSAA). In 1913, the US War Department encouraged the firearms and ammunition industry to establish an organization to share new technology and establish common standards for small arms and ammunition. SAMSAA was officially formed in 1918, however became inactive by the early 1920s. By the mid-1920s the United States was still suffe ...

404 Jeffery
The .404 Jeffery is a rifle cartridge designed for hunting large, dangerous game animals, such as the " Big Five" (elephant, rhino, cape buffalo, lion and leopard) of Africa. The cartridge is standardized by the C.I.P. and is also known as .404 Rimless Nitro Express. It was designed in 1905 by London based gunmaker W.J. Jeffery & Co to duplicate the performance of the .450/400 Nitro Express 3-inch in bolt-action rifles. The .404 Jeffery fired a bullet of .422 in (10.72 mm) diameter of either with a muzzle velocity of and muzzle energy of or with a muzzle velocity of and of energy. It is very effective on large game and is favored by many hunters of dangerous game. The .404 Jeffery was popular with hunters and game wardens in Africa because of its good performance with manageable recoil. By way of comparison, the .416 Rigby and .416 Remington Magnum cartridges fire .416 in (10.57 mm) bullets of 400 gr (26 g) at with a muzzle energy of approximately . These cartr ...

7 Mm STW
The 7mm Shooting Times Westerner, sometimes referred to as the 7mm STW began as a wildcat rifle cartridge developed by Layne Simpson in 1979.The 7mm STW (Shooting Times Westerner)
by Chuck Hawks
It is an case that has been "necked down" (narrowing the case opening) by 1 mm to accept 7 mm (.284 in) bullets. This cartridge is named after the magazine ''Shooting Times'' where Layne Simpson is a regular contributor.


Background

The 7mm STW graduated to commercial status when it was officially recognized by
