The six.5mm Grendel is really an intermediate cartridge jointly made by British-American armorer Bill Alexander, aggressive shooter Arne Brennan (of Houston, Texas) and Lapua ballistician Janne Pohjoispää, for a minimal-recoil, higher-precision rifle cartridge especially for the AR-15 System at medium/extended range (two hundred–800 garden). It is an enhanced variation from the six.5mm PPC. The 6.5mm Grendel cartridge was initially unveiled in May well 2003 within the Blackwater Training Facility in North Carolina, exactly where it remained supersonic at one,200 yd (1,a hundred m) selection and out-shot the seven.62mm NATO with only fifty percent the recoil. Since its introduction, it's proven to get a flexible cartridge and is also now growing into other firearm design and style platforms together with bolt-action rifles plus the Kalashnikov method.
The title "Grendel" is inspired through the legendary monster antagonist from the Previous English epic poem Beowulf. It absolutely was a trademark owned by Alexander Arms (Bill Alexander's organization in Radford, Virginia) and made at Radford Arsenal, until legally unveiled in 2010 for SAAMI standardization with collaboration from Hornady. The intention from the 6.5mm Grendel style and design was to create a highly effective STANAG journal-duration cartridge for the AR-15 platform that can arrive at 200–800 yd (180–730 m) and surpass the functionality with the indigenous five.56mm NATO/.223 Remington cartridge. Constrained by the dimension from the STANAG Publications, the Grendel's designers chose to make use of a shorter, much larger-diameter circumstance for bigger powder quantity while permitting Area to the prolonged, streamlined, substantial ballistic coefficient six.5mm (.264 cal.) bullets. Firing manufacturing facility-loaded ammunition with bullets ranging from 90 to 129 grains (5.8 to 8.four g), its muzzle velocity may differ from two,five hundred ft/s (760 m/s) with 129- and one hundred thirty-grain (eight.4 g) bullets to 2,900 ft/s (880 m/s) with 90 gr (five.eight g) bullets (very similar in velocity to Buy 6.5 Grendel Ammo Online the seventy seven-grain (five.0 g) five.fifty six mm round). Dependant upon their situation content and bullet bodyweight, 6.5mm Grendel cartridges weigh 14.seven to seventeen.8 grams (227 to 275 gr).
The case head diameter of the Grendel is similar to that of your five.6×39mm (.220 Russian), 7.sixty two×39mm and six.5mm PPC circumstances. This diameter is greater compared to 5.fifty six×45mm NATO, therefore necessitating the usage of a non-regular AR-fifteen bolt. The amplified scenario diameter leads to a small reduction during the journal ammo capacities. A 6.5mm Grendel journal Along with the very same dimensions to be a thirty-round STANAG journal will maintain 26 rounds of Grendel ammunition.
