.338 Marlin Express
The .338 Marlin Express is a cartridge developed by Marlin Firearms and Hornady. It is based on the .376 Steyr with a goal to duplicate the venerable .30-06 Springfield's performance in a cartridge compatible with lever-action firearms. The cartridge uses a slightly shorter, rimmed case to function in lever-action rifles with tubular magazines. As introduced in Hornady's LEVERevolution line of cartridges, it follows the design logic of the .308 Marlin Express which preceded it. The .338MX fires heavier .338 caliber bullets than the .308 Marlin Express at roughly the same velocity. It is chambered in Marlin's Model 338MX and 338MXLR rifles using the Marlin Model 336 action. Design History and Cartridge Performance Whereas the .308 Marlin Express began by modifying the .307 Winchester, Hornady and Marlin engineers started with a previous collaboration between Hornady and the Austrian arms maker Steyr, the .376 Steyr, when designing the .338 Marlin Express.

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 ...

444 Marlin
The .444 Marlin (10.9×57mmR) is a rifle cartridge designed in 1964 by Marlin Firearms and Remington Arms. It was designed to fill the gap left when the older .45-70 cartridge was not available in new lever-action rifles; at the time it was the largest lever-action cartridge available. The .444 resembles a lengthened .44 Magnum and provides a significant increase in velocity. It is usually used in the Marlin 444 lever-action rifle. Currently, Marlin, now owned by Ruger Firearms, does not offer the .444 chambering in any of their rifles. It remains to be seen if they will bring the chambering back into production. History In the mid-1960s the .45-70 had all but disappeared from the American marketplace. There was no big-bore cartridge available in a lever-action rifle in current production, so Marlin decided to create a new cartridge to fill this empty niche. They created what is essentially an elongated version of the .44 Magnum by making it nearly an inch longer to give it p ...

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 ...

300 Savage
The .300 Savage cartridge is a rimless, .30 caliber rifle cartridge developed by Savage Arms in 1920. It was designed to replace the less powerful .303 Savage in their popular Savage Model 1899 hammerless lever-action rifle, which they started to produce again as Model 99, as well as the new Savage Model 1920 bolt-action rifle. Despite having a short case in order to fit the original Model 99 magazine and a rather stumpy neck, the cartridge is capable of propelling a bullet at over with an effective range of over . Performance Pressure level for the .300 Savage is set by SAAMI at 46,000 CUP.Reloading data at Accurate Powder Official |
Foot-pound Force
The foot-pound force (symbol: ft⋅lbf, ft⋅lbf, or ft⋅lb ) is a unit of work or energy in the engineering and gravitational systems in United States customary and imperial units of measure. It is the energy transferred upon applying a force of one pound-force (lbf) through a linear displacement of one foot. The corresponding SI unit is the joule, though in terms of energy, one joule is not equal to one foot-pound. Usage The term ''foot-pound'' is also used as a unit of torque (see '' pound-foot (torque)''). In the United States this is often used to specify, for example, the tightness of a fastener (such as screws and nuts) or the output of an engine. Although they are dimensionally equivalent, energy (a scalar) and torque (a Euclidean vector) are distinct physical quantities. Both energy and torque can be expressed as a product of a force vector with a displacement vector (hence pounds and feet); energy is the scalar product of the two, and torque is the vector ...

Muzzle Energy
Muzzle energy is the kinetic energy of a bullet as it is expelled from the muzzle (firearm), muzzle of a firearm. Without consideration of factors such as aerodynamics and gravity for the sake of comparison, muzzle energy is used as a rough indication of the destructive potential of a given firearm or cartridge. The heavier the bullet and especially the Muzzle velocity, faster it moves, the higher its muzzle energy and the more damage it will do. Kinetic energy The general formula for the kinetic energy is E_\mathrm = \frac mv^2, where ''v'' is the velocity of the bullet and ''m'' is the mass of the bullet. Although both mass and velocity contribute to the muzzle energy, the muzzle energy is proportional to the mass while proportional to the ''square'' of the velocity. The velocity of the bullet is a more important determinant of muzzle energy. For a constant velocity, if the mass is doubled, the energy is doubled; however, for a constant mass, if the velocity is doubled, the ...

Muzzle Velocity
Muzzle velocity is the speed of a projectile (bullet, pellet, slug, ball/ shots or shell) with respect to the muzzle at the moment it leaves the end of a gun's barrel (i.e. the muzzle). Firearm muzzle velocities range from approximately to in black powder muskets, to more than in modern rifles with high-velocity cartridges such as the .220 Swift and .204 Ruger, all the way to for tank guns firing kinetic energy penetrator ammunition. To simulate orbital debris impacts on spacecraft, NASA launches projectiles through light-gas guns at speeds up to . Several factors, including the type of firearm, the cartridge, and the barrel length, determine the bullet's muzzle velocity. Projectile velocity For projectiles in unpowered flight, its velocity is highest at leaving the muzzle and drops off steadily because of air resistance. Projectiles traveling less than the speed of sound (about in dry air at sea level) are ''subsonic'', while those traveling faster are ''super ...

Grain (mass)
A grain is a unit of measurement of mass, and in the troy weight, avoirdupois, and apothecaries' systems, equal to exactly . It is nominally based upon the mass of a single ideal seed of a cereal. From the Bronze Age into the Renaissance, the average masses of wheat and barley grains were part of the legal definitions of units of mass. Expressions such as "thirty-two grains of wheat, taken from the middle of the ear" appear to have been ritualistic formulas. Another source states that it was defined such that 252.458 units would balance of distilled water at an ambient air-water pressure and temperature of and respectively. Another book states that Captain Henry Kater, of the British Standards Commission, arrived at this value experimentally. The grain was the legal foundation of traditional English weight systems, and is the only unit that is equal throughout the troy, avoirdupois, and apothecaries' systems of mass. The unit was based on the weight of a single grain of barl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Percussion Cap
The percussion cap, percussion primer, or caplock, introduced in the early 1820s, is a type of single-use percussion ignition device for muzzle loader firearm locks enabling them to fire reliably in any weather condition. Its invention gave rise to the caplock mechanism or percussion lock system which used percussion caps struck by the hammer to set off the gunpowder charge in rifles and cap and ball firearms. Any firearm using a caplock mechanism is a percussion gun. Any long gun with a cap-lock mechanism and rifled barrel is a percussion rifle. Cap and ball describes cap-lock firearms discharging a single bore-diameter spherical bullet with each shot. Description The percussion cap is a small cylinder of copper or brass with one closed end. Inside the closed end is a small amount of a shock-sensitive explosive material such as mercury fulminate (discovered in 1800; it was the only practical detonator used from about the mid-19th century to the early 20th century). ...

Tubular Magazine
A magazine, often simply called a mag, is an ammunition storage and feeding device for a repeating firearm, either integral within the gun (internal/fixed magazine) or externally attached (detachable magazine). The magazine functions by holding several cartridges within itself and sequentially pushing each one into a position where it may be readily loaded into the barrel chamber by the firearm's moving action. The detachable magazine is sometimes colloquially referred to as a " clip", although this is technically inaccurate since a clip is actually an accessory device used to help load ammunition into a magazine or cylinder. Magazines come in many shapes and sizes, from integral tubular magazines on lever-action and pump-action rifles and shotguns, that may hold more than five rounds, to detachable box magazines and drum magazines for automatic rifles and light machine guns, that may hold more than fifty rounds. Various jurisdictions ban what they define as " high-capa ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
