6×45mm SAW
The 6×45mm SAW describes an experimental series of rimless bottlenecked intermediate cartridges developed in the 1970s for the U.S. Army. The cartridges were produced in a variety of sizes and from a variety of materials. The intent was to develop a cartridge that would replace all 5.56×45mm NATO weapons as well as most 7.62×51mm NATO rifles and machine guns in the U.S. military. Eventually, the 5.56mm was retained and only the machine gun portion of the SAW (Squad Automatic Weapon) competition was successful. That program led to the M249 light machine gun. Note that the dimensions listed to the right are for 6×45mm SAW rounds. Three versions were produced for testing in the early 1970s. An aluminum-cased version was developed, as well as the about longer 6mm SAW Long. Design and development During the 1970s, the U.S. Army was looking to develop a new squad automatic weapon (SAW) that was lighter than the M60 machine gun with an effective range out to .

7mm BR Remington
The 7mm BR Remington / 7.2x38mm, commonly called the 7mm BR or the 7mm Benchrest Remington in long form, was an intermediate cartridge developed by Remington for the Remington XP-100 single-shot bolt-action handgun. The cartridge was developed for the Unlimited Class in the sport of Metallic silhouette shooting. Later it was introduced in the Remington Model XB-40 single-shot bolt-action rifle, which was specifically designed for the benchrest shooting community. The 7mm BR is based on previous Remington benchrest cartridges 6mm BR Remington and the .22 BR Remington cartridges. These cartridges in turn trace their origin to .308 Winchester via the .308×1.5-inch Barnes cartridge. The 7mm BR was designed by merely necking up the pre-existing 6mm BR Remington to accept a .28 caliber (7 mm) bullet. The cartridge is capable of developing with a bullet or with a bullet in a barrel. As a hunting cartridge it is adequate for smaller deer species and ranges under . With ...

M249 Light Machine Gun
The M249 SAW (Squad Automatic Weapon), formally the Light Machine Gun, 5.56 mm, M249, is the United States Armed Forces adaptation of the Belgian FN Minimi, a light machine gun manufactured by FN Herstal (FN). The M249 SAW is manufactured in the United States by the subsidiary FN Manufacturing LLC, a company in Columbia, South Carolina (FN America), and is widely used in the U.S. Armed Forces. The weapon was introduced in 1984 to address a lack of sustained automatic fire capability at the squad level. The M249 SAW combines the rate of fire of a machine gun with the accuracy and portability of an assault rifle. The M249 SAW is gas operated and air-cooled. It features a quick-change barrel (enabling the operator to rapidly replace an overheated or obstructed barrel) and a folding bipod attached to the front of the weapon (an M192 LGM tripod is also available.) The M249 SAW is normally belt-fed, although it is technically compatible with STANAG magazines (such as those used ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

6×45mm
The 6×45mm is a rimless, bottlenecked Cartridge (firearms), cartridge based on the .223 Remington or 5.56 NATO cartridge necked up to .243 (6mm). The cartridge is also known as the 6mm-223 Remington or 6mm/223. History Soon after the release of the .223 Remington as a commercial cartridge, shooters began experimenting with the cartridge in an attempt to improve its performance. Several of these experimenters necked up the .223 Remington to 6mm as the caliber bullets provided better external ballistic performance over caliber bullets. While several variations existed between early versions of these cartridges, the 6×45mm as we know it today became the standard version of the cartridge which is simply a necked up version of the .223 Remington without any further modifications or improvements made to it. General Information The cartridge's inherent accuracy was a carry over from the .222 Remington which already had a loyal following in benchrest shooting fraternity. Benchrest ...

Rodman Laboratories XM235
The Rodman Laboratories XM235 was one of the contenders for the squad automatic weapon (SAW) trials in 1975–1976. Development The Fabrique Nationale Minimi (designated XM249), Heckler & Koch HK23 (designated XM262), and a heavy-barreled version of the M16 (designated the XM106) were used as a control group. They were supposed to be used to figure out a baseline for the SAW contenders, which were the experimental group. They were already eliminated from consideration because they were chambered for the 5.56mm NATO cartridge.https://sadefensejournal.com/ordnance-oddities/ The XM235 they designed was merely a prototype and Rodman Laboratories didn't have the facilities or expertise to copy and mass produce it. When the XM235 was selected for the 5.56mm SAW trials, Maremont Corporation and Ford Aerospace and Communication bid on the rights to make an improved model rechambered in 5.56mm designated the XM238.

Aluminium
Aluminium (or aluminum in North American English) is a chemical element; it has chemical symbol, symbol Al and atomic number 13. It has a density lower than that of other common metals, about one-third that of steel. Aluminium has a great affinity towards oxygen, passivation (chemistry), forming a protective layer of aluminium oxide, oxide on the surface when exposed to air. It visually resembles silver, both in its color and in its great ability to reflect light. It is soft, magnetism, nonmagnetic, and ductility, ductile. It has one stable isotope, 27Al, which is highly abundant, making aluminium the abundance of the chemical elements, 12th-most abundant element in the universe. The radioactive decay, radioactivity of aluminium-26, 26Al leads to it being used in radiometric dating. Chemically, aluminium is a post-transition metal in the boron group; as is common for the group, aluminium forms compounds primarily in the +3 oxidation state. The aluminium cation Al3+ ...

Squad Automatic Weapon
A squad automatic weapon (SAW), also known as a section automatic weapon or light support weapon (LSW), is a man-portable automatic firearm attached to infantry squads or sections as a source of rapid direct firepower. Weapons fulfilling this role can be light machine guns, or modified selective-fire rifles fitted with a heavier barrel, bipod and a belt/ drum-fed design. Squad automatic weapons usually fire the same cartridge (though heavier- bullet variants are preferred) as the assault rifles or battle rifles carried by other members of the unit. This reduces logistical requirements by making it only necessary to supply one type of service ammunition to a unit. These weapons are light enough to be carried and operated by one infantryman, unlike medium machine guns (such as the M1919 Browning) that require a crew to operate at full effectiveness; or heavy machine guns (such as the M2 Browning or the DShK) which fire more powerful cartridges but are also crew-s ...

280 British
The .280 British was an experimental rimless bottlenecked intermediate rifle cartridge. It was later designated 7 mm MK1Z, and has also been known as .280/30, .280 Enfield, 7 mm FN Short and 7×43mm. Like most armed forces in the immediate post-World War II era, the British Army began experimenting with lighter rounds after meeting the German StG 44 in combat. The Army began development in the late 1940s, with subsequent help from Fabrique Nationale in Belgium and the Canadian Army. The .280 British was tested in a variety of rifles and machine guns including the EM-2, Lee–Enfield, FN FAL, Bren, M1 Garand and Taden gun. Despite its success as an intermediate cartridge, the .280 British was not considered powerful enough by the US Army and several variants of the .280 British were created in an attempt to appease the US Army. However, the US Army continued to reject these variants, ultimately adopting the cartridge that was then designated the 7.62×51mm NA ...
