Introduction
Federal XM193 5.56x45mm 55 GR FMJ 500 Rounds, Federal American Eagle 5.56mm NATO Ammo 55 Grain Full Metal Jacket 1000 Rounds Bulk review offers the following information; Federal American Eagle Ammunition has been loaded and passed true NATO specifications.
Moreover, This is the same ammunition that is currently being used by the US Military and met their strict quality assurance standards and specifications. Thus, This Federal American Eagle 5.56mm M193 NATO ammunition is the perfect example of superiority that goes into making Federal ammo with its re-loadable brass casing and finely designed boxer primers.
In addition, Like any Federal product, the XM193 product is a brand new, original, first-quality product manufactured at Lake City Army Ammunition Plant for Federal Cartridges made to Federal specifications typical for commercial ammunition. furthermore, Shooters can have ease of mind knowing that all XM193 products are the same product, hence, made to the same specifications, regardless of the SKU or part number. (ie. XM193C is the same as XM193F, XM193CBP and etc…) again, the only difference is the package configuration. Thus, This is an added bonus for hunters and shooters who have calibrated firearms to match specific ammunition.
The 5.56mm ammo features brand new virgin never never-fired annealed brass casings, a lead core full metal jacket bullet that is not magnetic, and a non-corrosive primer. This Federal 5.56mm ammo can be reloaded up to 7 times for those shooters that reload their 5.56mm NATO ammunition. Federal XM193 5.56mm delivers a muzzle velocity of 3240 feet per second and muzzle energy of 1282 ft. lbs.
The British had extensive evidence through their own experimentation with intermediate cartridges since 1945 and were on the point of adopting the .280 (7 mm) cartridge when the selection of 7.62×51mm (.300) as the NATO standard was made. The FN company had also been involved in the development of the .280 round, including developing a version of the FN FAL in .280. Concerns about the recoil and overall effectiveness of 7.62 mm were overruled by the US, and the other NATO nations accepted that standardization was more important than the selection of a cartridge that was otherwise ideal.
The development of the cartridge that eventually became the .223 Remington (from which 5.56mm NATO would eventually be developed) would be intrinsically linked to the development of a new lightweight combat rifle. The cartridge and rifle were developed as one unit by Fairchild Industries, Remington Arms, and several engineers working toward a goal developed by the U.S. Continental Army Command (CONARC). Early development work began in 1957. A project to create a small-caliber, high-velocity (SCHV) firearm was created. Eugene Stoner of Armalite was invited to scale down the AR-10 (7.62mm) design. Winchester was also invited to participate. The parameters that were requested by CONARC:
- .22 caliber
- Bullet exceeding supersonic speed at 500 yards (457 metres)
- Rifle weight of 6 pounds (2.72 kilograms)
- Magazine capacity of 20 rounds
- Select fire for both semi-automatic and fully automatic use
- Penetration of US steel helmet through one side at 500 yd (457 m)
- Penetration of 0.135 inches (3.43 millimetres) steel plate at 500 yd (457 m)
- Accuracy and ballistics equal to M2 ball ammunition (.30-06 Springfield) out to 500 yd (457 m)
- Wounding ability equal to M1 carbine
Springfield Armory‘s Earle Harvey lengthened the .222 Remington cartridge case to meet the requirements. It was then known as the .224 Springfield. Concurrently with the SCHV project, Springfield Armory was developing a 7.62mm rifle. Harvey was ordered to cease all work on the SCHV to avoid any competition for resources.
Eugene Stoner of Armalite (a division of Fairchild Industries) had been advised to produce a scaled-down version of the 7.62mm AR-10 design. In May 1957, Stoner gave a live-fire demonstration of the prototype of the AR-15 for General Willard G. Wyman, Commander-in-Chief of CONARC. As a result, CONARC ordered rifles to be tested. Stoner and Sierra Bullet’s Frank Snow began work on the .222 Remington cartridge. Using a ballistic calculator, they determined that a 55-grain bullet would have to be fired at 3,300 ft/s (1,006 m/s) to achieve the 500-yard performance necessary.
Robert Hutton (technical editor of Guns & Ammo magazine) started the development of a powder load to reach the 3,300 ft/s (1,006 m/s) goal. He used DuPont IMR4198, IMR3031, and an Olin powder to work up loads. Testing was done with a Remington 722 rifle with a 22-inch Apex barrel. During a public demonstration, the round successfully penetrated the U.S. steel helmet as required. However, testing showed chamber pressures to be excessively high.
Stoner contacted both Winchester and Remington about increasing the case capacity. Remington created a larger cartridge called the “.222 Special”, which was loaded with DuPont IMR4475 powder. During parallel testing of the T44E4 (future M14) and the AR-15 in 1958, the T44E4 experienced 16 failures per 1,000 rounds fired compared to 6.1 for the AR-15.
Due to several different .222 caliber cartridges being developed for the SCHV project, the 222 Special was renamed .223 Remington in 1959. In May of that year, a report was produced stating that five- to seven-man squads armed with AR-15 rifles had higher hit probabilities than 11-man squads armed with M-14 rifles. At a 4th of July picnic, Air Force General Curtis LeMay fired an AR-15 and was very impressed with it. He ordered a number of them to replace M2 carbines that were in use by the Air Force. By November, testing at Aberdeen Proving Ground showed that the AR-15 failure rate had declined to 2.5 failures per 1,000 rounds, resulting in the M-16 being approved for Air Force Trials.
Marksmanship testing in 1961 comparing the M-16 to the M-14 indicated that 43% of M-16 shooters achieved “expert” while only 22% of M-14 shooters did. General LeMay subsequently ordered 80,000 rifles.
In the spring of 1962, Remington submitted the specifications of the .223 Remington to the Sporting Arms and Ammunition Manufacturers’ Institute (SAAMI). In July 1962, operational testing ended with a recommendation for the adoption of the M-16 rifle chambered in a .223 Remington.
In September 1963, the .223 Remington cartridge was officially accepted and named “Cartridge, 5.56mm ball, M193”. The specification includes a Remington-designed bullet and the use of IMR4475 powder which resulted in a muzzle velocity of 3,250 ft/s (991 m/s) and a chamber pressure of 52,000 psi.
In 1970, NATO members signed an agreement to select a second, smaller caliber cartridge to replace the 7.62×51mm NATO cartridge. Of the cartridges tendered, the .223 Remington (M193) was the basis for a new design created by FN Herstal. The FN-created cartridge was named “5.56×45mm NATO” with a military designation of SS109 in NATO and M855 in the U.S.These new SS109 ball cartridges required a 228 mm (1-in-9 inch) twist rate while adequately stabilizing the longer L110 tracer projectile required an even faster, 178 mm (1-in-7 inch), twist rate.
The Belgian 62 gr SS109 round was chosen for standardization as the second NATO standard rifle cartridge which led to the October 1980 STANAG 4172. The SS109 used a 62 gr full metal jacket bullet with a seven-grain mild steel tip to move the center of gravity rearward, increasing flight stability and thereby the chances of striking the target tip-first at longer ranges, in part to meet a requirement that the bullet be able to penetrate through one side of a WWII U.S. M1 helmet at 800 meters (which was also the requirement for the 7.62×51mm NATO). An actual helmet was not used for developmental testing, but an SAE 1010 or SAE 1020 mild steel plate, positioned to be struck at exactly 90 degrees. It had a slightly lower muzzle velocity but better long-range performance due to higher sectional density and a superior drag coefficient. This requirement made the SS109 (M855) round less capable of fragmentation than the M193.
The .223 Remington cartridge inspired an international tendency toward relatively small-sized, lightweight, high-velocity military service cartridges that allow a soldier to carry more ammunition for the same weight compared to their larger and heavier predecessor cartridges, have favorable maximum point-blank range or “battle zero” characteristics, and produce relatively low bolt thrust and free recoil impulse, favoring lightweight arms design and automatic fire accuracy. Similar intermediate cartridges were developed and adopted by the Soviet Union in 1974 (5.45×39mm) and by the People’s Republic of China in 1987 (5.8×42mm).
