The six.5mm Grendel is really an intermediate cartridge jointly created by British-American armorer Invoice Alexander, aggressive shooter Arne Brennan (of Houston, Texas) and Lapua ballistician Janne Pohjoispää, being a reduced-recoil, high-precision rifle cartridge specifically for the AR-15 System at medium/long range (two hundred–800 lawn). It can be an improved variation from the six.5mm PPC. The 6.5mm Grendel cartridge was initial unveiled in Might 2003 within the Blackwater Teaching Facility in North Carolina, in which it remained supersonic at one,200 yd (one,100 m) selection and out-shot the 7.62mm NATO with only 50 percent the recoil. Because its introduction, it's got confirmed being a versatile cartridge which is now expanding into other firearm layout platforms including bolt-action rifles as well as Kalashnikov program.
The identify "Grendel" is inspired with the legendary monster antagonist in the Outdated English epic poem Beowulf. It absolutely was a trademark owned by Alexander Arms (Bill Alexander's corporation in Radford, Virginia) and created at Radford Arsenal, until finally lawfully produced in 2010 for SAAMI standardization with collaboration from Hornady. The objective on the six.5mm Grendel style and design was to create a highly effective STANAG journal-duration cartridge with the AR-15 platform that might access two hundred–800 yd (a hundred and eighty–730 m) and surpass the overall performance on the indigenous five.56mm NATO/.223 Remington cartridge. Constrained via the dimension of the STANAG magazines, the Grendel's designers decided to make use of a shorter, more substantial-diameter scenario for bigger powder quantity while permitting Room for your extended, streamlined, substantial ballistic coefficient 6.5mm (.264 cal.) bullets. Firing manufacturing facility-loaded ammunition with bullets ranging from 90 to 129 grains (5.8 to eight.four g), its muzzle velocity may differ from two,five hundred ft/s (760 m/s) with 129- and one hundred thirty-grain (8.4 g) bullets to two,900 ft/s (880 m/s) with ninety gr (5.8 g) bullets (equivalent in velocity to some 77-grain (5.0 6.5 Grendel Ammo For Sale g) five.fifty six mm spherical). Dependant upon their scenario content and bullet fat, 6.5mm Grendel cartridges weigh 14.seven to seventeen.8 grams (227 to 275 gr).
The case head diameter from the Grendel is similar to that of your five.6×39mm (.220 Russian), 7.sixty two×39mm and six.5mm PPC situations. This diameter is more substantial as opposed to 5.56×45mm NATO, thus necessitating the usage of a non-normal AR-15 bolt. The increased circumstance diameter ends in a small reduction in the journal ammo capacities. A 6.5mm Grendel magazine While using the similar dimensions as being a 30-spherical STANAG journal will maintain 26 rounds of Grendel ammunition.
