8 Mm Remington Magnum
The 8mm Remington Magnum belted rifle cartridge was introduced by Remington Arms Company in 1978 as a new chambering for the model 700 BDL rifle. The 8mm Remington Magnum's parent case is the .375 H&H Magnum. It is a very long and powerful cartridge that cannot be used in standard length actions, such as those that accommodate the .30-06 Springfield. Background The 8mm Remington Magnum was intended to compete with the .300 Weatherby Magnum and .338 Winchester Magnum. Remington's decision to use a metric bullet may have been prompted by their past success with the 7 mm bore diameter. Even though the 8mm Remington Magnum has never been very popular, it is a very suitable cartridge for the hunting of elk, moose, caribou, and larger African antelope. However, the .338 Winchester Magnum had a 30-year head start on the market, and is short enough for medium length actions, which increases the models of rifles it could be produced in. It is also available with heavier bu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
308 Winchester
The .308 Winchester is a smokeless powder Rim (firearms), rimless bottlenecked rifle Cartridge (firearms), 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 7.62×51mm NATO#Development, T65 series of experimental cartridges. The original experimental case design by the Frankford Arsenal was designated "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 walls. The later T65 iterations were lengthened compared to the original T65 case and provided a ballistic performance roughly equal to the U.S. mi ...

Rifling
Rifling is the term for helical grooves machined into the internal surface of a firearms's barrel for imparting a spin to a projectile to improve its aerodynamic stability and accuracy. It is also the term (as a verb) for creating such grooves. The opposite of rifling is smoothbore. Rifling is measured in ''twist rate'', the distance the rifling takes to complete one full revolution, expressed as a ratio with 1 as its base (e.g., 1:). A shorter distance/lower ratio indicates a faster twist, generating a higher spin rate (and greater projectile stability). The combination of length, weight, and shape of a projectile determines the twist rate needed to gyroscopically stabilize it: barrels intended for short, large-diameter projectiles such as spherical lead balls require a very low twist rate, such as 1 turn in 48 inches (122 cm). Barrels intended for long, small-diameter projectiles, such as the ultra-low-drag 80-grain 0.223 inch bullets (5.2 g, 5.56&nb ...

Wildcat Cartridge
A wildcat cartridge, often shortened to wildcat, is a custom-made cartridge (weaponry), cartridge for which ammunition and/or firearms are not mass-produced. These cartridges are often created as experimental variants to optimize a certain ballistic performance characteristic (such as the power, size, or efficiency) of an existing commercial cartridge, or may merely be intended as novelty items. Developing and using wildcat cartridges does not generally serve a purpose in military or law enforcement; it is more a hobby for serious sport 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. ...

416 Remington Magnum
The .416 Remington Magnum is a .416 caliber (10.57 mm) Cartridge (firearms), cartridge of belted bottlenecked design. The cartridge was intended as a Big-game hunting, dangerous game hunting cartridge and released to the public in 1989. The cartridge uses the case of the 8 mm Remington Magnum as a parent cartridge. When the cartridge was released in 1988, author Frank Barnes (gunsmith), Frank C. Barnes considered the .416 Remington Magnum to be the "most outstanding factory cartridge introduced in decades". The cartridge was conceived as a less costly alternative to the .416 Rigby cartridge and was intended to replace the latter. While today the .416 Remington Magnum is considered in the field the most popular of the .416 cartridges, the .416 Remington did not replace the .416 Rigby as had been anticipated. Rather, it sparked a renewed interest in the .416 caliber (10.57 mm) cartridges which led to the revival of the .416 Rigby and the introduction of other .416 cartri ...

7mm Remington Ultra Magnum
The 7mm Remington Ultra Magnum or 7mm RUM is a 7mm rifle cartridge introduced by Remington Arms in 2001. Overview The 7mm RUM was created using the .404 Jeffery case which was also used to develop the .375 RUM .300 RUM, and .338 RUM . By necking down the .300 RUM to suit the .284 or 7mm projectile, Remington produced a non-belted case with a head diameter that is somewhat larger than the belt diameter of the original belted numbers. The resulting case has significantly more capacity than any conventional belted magnum. Compared to the 7mm Remington Magnum, top 7mm RUM loads deliver 25% more energy at 300 yards. Such performance demands a price and in this case, that is a large muzzle blast, sharp recoil and short barrel life. The 7mm Ultra Magnum boasts the largest case of any commercial 7mm cartridge. The 7mm Ultra Magnum (7mmx72) is a different cartridge than the similarly named 7mm Short Action Ultra Magnum cartridge (7mmx51). The two are not interchangeable. See also ...

Lazzeroni
Lazzeroni Arms Company is a US firearms and firearm cartridge maker based in Tucson, Arizona. Lazzeroni was founded by John Lazzeroni and is known for designing and producing long range hunting rifles and high speed cartridges. Lazzeroni rifles Initially Lazzeroni rifles were made using Remington Model 700 actions, but due to feeding problems and concerns about the action's strength, the company subsequently used a specially modified McBros action with a custom magazine assembly. More recently, the company has used specially made SAKO actions. Lazzeroni's standard rifle, the L2000ST, has a barrel and weighs without a scope. The company's lightweight mountain rifle, the L2000SA, has a barrel and weighs without a scope.

7mm Shooting Times Westerner
The 7mm Shooting Times Westerner, sometimes referred to as the 7mm STW, began as a wildcat rifle cartridge developed by Layne Simpson, Field Editor of Shooting Times, in 1979. It is an 8mm Remington Magnum The 8mm Remington Magnum belted rifle cartridge was introduced by Remington Arms Company in 1978 as a new chambering for the model 700 BDL rifle. The 8mm Remington Magnum's parent case is the .375 H&H Magnum. It is a very long and powerful ... case that has been "necked down" (narrowing the case opening) by 1 mm to accept 7 mm caliber, 7 mm (.284 in) bullets. Background The first major company to produce the 7mm STW was A-Square in 1994. The 7mm STW graduated to commercial status when it was officially recognized by SAAMI in 1996, and the Remington Arms Company started to produce it in 1997, with other ammunition manufacturers following. As of 2019, Federal Premium Ammunition is the only major manufacturer to still offer it on a regular basis, but smaller manufac ...

8×64mm S
The 8×64mm S (also unofficially known as the 8×64mm S Brenneke) (the S means it is intended for 8.2 mm (.323 in) groove diameter bullets) is a rimless bottlenecked centerfire cartridge developed as a military service round for the German Army who never issued it. As is customary in European cartridges the 8 denotes the 8 mm bullet caliber and the 64 denotes the 64 mm (2.52 in) case length. The 8×64mm is a hunting cartridge in central Europe and can due to its maximal overall length fairly easily be chambered in standard sized military Mauser Gewehr 98 bolt-action rifles. In such military M98 bolt actions the magazine boxes, however, have to be adapted by a competent gunsmith to function properly with the 8×64mm S cartridge, since the M98 internal magazine boxes feature an internal magazine length of .

325 WSM
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 and 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 c ...

8×68mm S
The 8×68mm S Rim (firearms), rebated rim bottlenecked centerfire rifle Cartridge (firearms), cartridge was developed in the 1930s by August Schüler of the ''August Schüler Waffenfabrik, Suhl, Germany'' as a magnum hunting cartridge that would just fit and function in standard-sized Mauser 98 bolt-action rifles. The bore has the same lands and grooves diameters as the German 7.92×57mm Mauser service cartridge (designated as "S-bore"). This is one of the early examples where a completely new rifle cartridge (the 6.5×68mm and 8×68mm S have no other cartridge as parent case) was developed by a gunsmith to fit a specific popular and widespread type of rifle. History The German ammunition manufacturer introduced both cartridges commercially in the spring of 1939. With the official certification of the .375 Hölderlin and the 8.5×68mm Fanzoj this German 68 mm "family" of magnum rifle cartridges that all share the same basic cartridge case got expanded in the 21st century. ...
