.30-03 Springfield
The .30-03 Springfield (7.62×65mm) was a short-lived cartridge developed by the United States in 1903, to replace the .30-40 Krag in the new Springfield 1903 rifle. The .30-03 was also called the .30-45, since it used a 45 grain () powder charge; the name was changed to .30-03 to indicate the year of adoption.''Cartridges of the World'' (11th Edition), Frank C. Barnes, Edited by Stan Skinner, Gun Digest Books, 2006, pp.130,164 It used a 220 grain () roundnose bullet. It was replaced after only three years of service by the .30-06, firing a spitzer bullet giving better ballistic performance. Initial development The .30-03 was developed to replace the .30-40 Krag cartridge used in the Krag–Jørgensen rifle, which was the first bolt action rifle adopted by the US military, and the first that used smokeless powder. The Krag–Jørgensen rifle had some serious limitations compared to the new Mauser rifles being used by European armies; it was loaded one round at a time, ...

Soft Point Bullet
A soft-point bullet (SP), also known as a soft-nosed bullet, is a jacketed expanding bullet with a soft metal core enclosed by a stronger metal jacket left open at the forward tip. A soft-point bullet is intended to expand upon striking flesh to cause a wound diameter greater than the bullet diameter. Jacketed soft point bullets are usually abbreviated ''JSP'' in the ammunition and reloading industry. Evolution Lead-alloy bullets used with gunpowder firearms were unsatisfactory at the bullet velocities available from rifles loaded with nitrocellulose propellants such as cordite. By the late 19th century, lead-alloy bullets were being enclosed within a jacket of stronger mild steel or copper alloyed with nickel or zinc to reliably impart stabilizing rotation in rifled barrels. The lead-alloy core was swaged into a cup of the stronger metal covering the front and sides of the core, but leaving some of the core exposed on the base of the bullet. The bullet jacket may be described ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
American Rifleman
''American Rifleman'' is a United States-based monthly shooting and firearms interest publication, owned by the National Rifle Association (NRA). It is the 33rd-most-widely-distributed consumer magazine and the NRA's primary magazine. The magazine has its headquarters in Fairfax, Virginia. History Arthur Corbin Gould, an avid shooter and member of the Massachusetts Rifle Association, published ''The Rifle'' in 1885 as an effort to focus discussion on the sport of rifle shooting. ''The Rifle'' later changed its title to ''Shooting and Fishing'' in 1888, branching out into other outdoor sports. In 1894, while the magazine was titled ''Shooting and Fishing'', Gould attended the National Rifle Association matches held at Sea Girt and was impressed with the level of competition, leading him to write several editorials urging the public to join. This call eventually led to the revitalization of the National Rifle Association and established a Board of Directors to help manage the ...

Pistol And Rifle Cartridges
A pistol is a handgun, more specifically one with the chamber integral to its gun barrel, though in common usage the two terms are often used interchangeably. The English word was introduced in , when early handguns were produced in Europe, and is derived from the Middle French ''pistolet'' (), meaning a small gun or knife. In colloquial usage, the word "pistol" is often used 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, while the older single-shot and lever action, manual repeating pistols are now rarely seen and used primarily for nostalgic hunting and historical reenactment, and the fully automatic machine pistols are uncommon in civilian usage due to generally poor recoil-controllability and strict gun laws, laws and regulations ...

280 Remington
The ''.280 Remington'', also known as the 7mm-06 Remington and 7mm Express Remington, was introduced in 1957 for the Remington model 740, 760, 721, and 725 rifles. History Having been released 32 years after the .270 Winchester, it had somewhat unspectacular sales. Remington renamed the cartridge in late 1978 to 7mm-06 Remington. but just before the end of the year, they renamed it again, calling it the 7 mm Express in an attempt to increase sales. This resulted in people confusing it with the 7 mm Remington Magnum, and Remington changed the name back to .280 in 1981.The Versatile 280 at Outdoor Life By Jim Carmichel, September 18, 2007 Specifications The .280 is based on the .30-06[...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
270 Winchester
The .270 Winchester is a rifle cartridge developed by Winchester Repeating Arms Company in 1923 and unveiled in 1925 as a chambering for their bolt-action Model 54The Complete Reloading Manual for the .270 Winchester, Loadbooks USA, Inc., 2004, pp.13,19 to become arguably the flattest shooting cartridge of its day, only competing with the .300 Holland & Holland Magnum, also introduced in the same year. As the .280 Remington, and the .30-06 Springfield, the .270 Winchester derived from the .30-03 parent case and the bore diameter was likely inspired by 7mm Mauser. The .270 Winchester uses a .270 inch (6.86 mm) bore diameter and a .277 inch (7.04 mm) bullet diameter. History Introduced in 1925 along with the Winchester Model 54 bolt action rifle under the name "270 WCF" (270 Winchester Centerfire), the .270 Winchester was not an immediate success due to the popularity of the relatively recently introduced .30-06 Springfield, chambered for the M1903 Springfield bolt ...

Firearm Action
In firearms terminology, an action is the functional mechanism of a breech-loading firearm that handles (loads, locks, fires, extracts and ejects) the ammunition cartridges, or the method by which that mechanism works. Actions are technically not present on muzzleloaders, as all those are single-shot firearms with a closed off breech with the powder and projectile manually loaded from the muzzle. Instead, the muzzleloader ignition mechanism is referred to as the ''lock'' (e.g. matchlock, flintlock, caplock). Actions can be categorized in several ways, including single action versus double action, break action versus bolt action, and others. The term action can also include short, long, and magnum if it is in reference to the length of the rifle's receiver and the length of the bolt. The short action rifle usually can accommodate a cartridge length of or smaller. The long action rifle can accommodate a cartridge of , and the magnum action rifle can accommodate cartridges ...

30-06
The .30-06 Springfield cartridge (pronounced "thirty-aught-six" ), 7.62×63mm in metric notation, and called the .30 Gov't '06 by Winchester, was introduced to the United States Army in 1906 and later standardized; it remained in military use until the late 1970s. The ".30" refers to the caliber of the bullet in inches. The "06" refers to the year the cartridge was adopted, 1906. It replaced the .30-03, 6mm Lee Navy, and .30-40 Krag cartridges. The .30-06 remained the U.S. Army's primary rifle and machine gun cartridge for nearly 50 years before being replaced by the 7.62×51mm NATO and 5.56×45mm NATO, both of which remain in current U.S. and NATO service. It remains a very popular sporting round, with ammunition produced by all major manufacturers. History In the early-1890s, the U.S. military adopted the smokeless powder .30-40 Krag rimmed cartridge. The 1894 version of that cartridge used a round-nose bullet. Around 1901, the U.S. started developing an experimental rimles ...

External Ballistics
External ballistics or exterior ballistics is the part of ballistics that deals with the behavior of a projectile in flight. The projectile may be powered or un-powered, guided or unguided, spin or fin stabilized, flying through an atmosphere or in the vacuum of space, but most certainly flying under the influence of a gravitational field. Gun-launched projectiles may be unpowered, deriving all their velocity from the propellant's ignition until the projectile exits the gun barrel. However, exterior ballistics analysis also deals with the trajectories of rocket-assisted gun-launched projectiles and gun-launched rockets; and rockets that acquire all their trajectory velocity from the interior ballistics of their on-board propulsion system, either a rocket motor or air-breathing engine, both during their boost phase and after motor burnout. External ballistics is also concerned with the free-flight of other projectiles, such as balls, arrows etc. Forces acting on the projectile W ...

30 Army
The .30-40 Krag (also known as .30 U.S. and .30 Army) was a cartridge developed in the early 1890s to provide the U.S. armed forces with a smokeless powder cartridge suited for use with modern small-bore repeating rifles to be selected in the 1892 small arm trials. Since the cartridge it was replacing was the .45-70 Government, the round was considered ''small-bore'' at the time. The design selected was ultimately the Krag–Jørgensen, formally adopted as the M1892 Springfield. It was also used in M1893 and later Gatling guns. History and development Though the U.S. Navy and Marine Corps had adopted limited numbers of smokeless powder and bolt-action rifles, the .30-40 was the first cartridge adopted by the US Army that was designed from the outset for smokeless powder. It was patterned after .303 British, to which it is very similar geometrically. After a brief experiment with a 230-grain bullet loading, the .30 Army loading was standardized in 1894 using a metal-jacketed ...

Gatling Gun
The Gatling gun is a rapid-firing multiple-barrel firearm invented in 1861 by Richard Jordan Gatling. It is an early machine gun and a forerunner of the modern electric motor-driven rotary cannon. The Gatling gun's operation centered on a cyclic multi-barrel design which facilitated cooling and synchronized the firing-reloading sequence. As the handwheel is cranked, the barrels rotate and each barrel sequentially loads a single cartridge from a top-mounted magazine, fires off the shot when it reaches a set position (usually at 4 o'clock), then ejects the spent casing out of the left side at the bottom, after which the barrel is empty and allowed to cool until rotated back to the top position and gravity-fed another new round. This configuration eliminated the need for a single reciprocating bolt design and allowed higher rates of fire to be achieved without the barrels overheating quickly. One of the best-known early rapid-fire firearms, the Gatling gun saw occasional use ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
