The 6.5mm Grendel is an intermediate cartridge jointly designed by British-American armorer Bill Alexander, competitive shooter Arne Brennan (of Houston, Texas) and Lapua ballistician Janne Pohjoispää, as a low-recoil, high-precision rifle cartridge specifically for the AR-15 platform at medium/long range (200–800 yard).
The 6.5mm Creedmoor designated as 6.5 Creedmoor by SAAMI, and as 6,5 Creedmoor by the C.I.P. [ 4 ] is a centerfire rifle cartridge introduced by Hornady in 2007. [ 6 ] It was developed by Hornady senior ballistics scientist Dave Emary in partnership with Dennis DeMille, the vice-president of product development at Creedmoor Sports, hence the name.
The 300 AAC Blackout was designed to achieve energies similar to the 7.62×39mm Soviet in an AR-15 while using standard AR magazines at their full capacity. The 7.62 Soviet's cartridge taper prevented reliable feeding in AR magazines and created wear on the bolt.
These wildcats also push forward the shoulder of the same necked Grendel case similar to the Turbo 40, yielding more powder capacity. 6.5 g (100 gr) or heavier grain VLD boat-tail bullets have to be seated deeply within the case neck, however, rendering some of these volume gains illusory but there is an increase in volume even with the longer ...
Magpul has been granted a patent [47] for a STANAG-compatible casket magazine, [48] and such a magazine was also debuted by SureFire in December 2010, and is now sold as the MAG5-60 and MAG5-100 high capacity magazine (HCM) in 60 and 100 round capacities, respectively, in 5.56mm for AR-15 compatible with M4/M16/AR-15 variants and other firearms ...
Not all AR-308 rifles use magazines compatible with the SR-25 pattern. For example, HK417 /MR308/MR762 uses a proprietary design. Notably, Armalite switched from their original pattern magazines to modified M14 magazines in 1996 with their new AR-10B model, [ 2 ] but reintroduced their original (SR-25 pattern) magazine design with the AR-10A ...
The 6mm ARC utilizes the same bolt head size as the 6.5mm Grendel, and 6.5mm Grendel-compatible AR-pattern box magazines have also been used successfully with the 6mm ARC. [8] The 6mm ARC therefore can also be a suitable chambering for shorter "mini-action" bolt-action rifles , such as the CZ 527 bolt action rifle mentioned previously.
With normal bullet weights between 300 and 400 grains (19 and 26 g), overall cartridge length shorter than that of an AR-15 magazine well, and holding to pressures of 33,000 psi limited by the AR bolt strength system, [2] the .50 Beowulf is best described as a low-velocity, heavy caliber, making its ballistics roughly equivalent to those of ...
