The cartridge was designed specifically for long-range target shooting,[7] although it has success in gamehunting.[8] Bullet-for-bullet, the 6.5mm Creedmoor achieves a slower muzzle velocity than longer cartridges such as the 6.5-284 Norma or magnum cartridges such as the 6.5mm Remington Magnum. However, due to its overall length of 2.825 inches (71.8 mm), it is capable of chambering in short-action rifles.
It was developed in partnership by Hornady Senior Ballistics Scientist Dave Emary and Dennis DeMille, VP of product development for Creedmoor Sports, hence the name.
Design considerations[edit]
In general, 6.5 mm (.264') bullets are known for their relatively-high sectional density[8] and ballistic coefficients, and see success in rifle competition. The 6.5mm Creedmoor was designed for target shooting at longer ranges, and as such, couples a sensible case volume (3.40 ml) to bore area (34.66 mm2/0.3466 cm2) ratio with ample space for loading relatively-long slender projectiles providing good aerodynamic efficiency and external ballistic performance for the projectile diameter.[4]For some loads, the 6.5mm Creedmoor is capable of duplicating the muzzle velocity[2] or trajectory[10] of the .300 Winchester Magnum while generating significantly-lower recoil, based on lighter projectile weight. This cartridge is designed for a bolt-face diameter of .473 inches (roughly 12 mm), conversion of a short action rifle to another caliber (such as the .22-250 Remington, .243 Winchester or .300 Savage) with similar bolt-face diameter generally requires little more than a simple barrel change, or on the Armalite-style AR-10 series, a complete upper-assembly.
Cartridge dimensions[edit]
The 6.5mm Creedmoor has 3.40 ml (52.5 grains H2O) cartridge case capacity.
6.5mm Creedmoor maximum C.I.P. cartridge dimensions. All sizes in millimeters (mm).[4]
Americans define the shoulder angle at alpha/2 = 30 degrees. The common rifling twist rate for this cartridge is 203 mm (1 in 8 in), 6 grooves, Ø lands = 6.50 mm (0.256 in), Ø grooves = 6.71 mm (0.264 in), land width = 2.29 mm (0.090 in), and the primer type is large rifle or small rifle depending on the cartridge case manufacturer.[4]
According to the official C.I.P. (Commission Internationale Permanente pour l'Epreuve des Armes à Feu Portatives) rulings, 6.5mm Creedmoor can handle up to 435.00 MPa (63,091 psi) Pmax piezo pressure. In C.I.P. regulated countries, every rifle cartridge combo has to be proofed at 125% of this maximum C.I.P. pressure to certify for sale to consumers.In CIP-regulated areas, 6.5mm Creedmoor chambered arms are proof-tested at 543.80 MPa (78,872 psi) PE piezo pressure.[4]
The SAAMI Maximum Average Pressure (MAP) for this cartridge is 62,000 psi (427.47 MPa) piezo pressure[11]
Performance[edit]
The 6.5mm Creedmoor is a medium-power cartridge comparable to the .260 Remington and 6.5×47mm Lapua.[12] Three-hundred yard energy using 129-grain Hornady SST bullets is listed by an independent reviewer as 1,641 foot-pounds force (2,225 J).[13] For the 140 grain bullet at 2,700 feet per second (823 m/s) initial velocity, another reviewer reports an MPBR[14] for a six-inch-high target of 265 yards (242 m), and reports a manufacturer-claim of 'almost 1,600 ft⋅lbf (2,169 J)' of retained energy at 300 yards (274 m) using a 24 inches (610 mm) barrel.[15] SAAMI test data confirms 6.5 mm Creedmoor, 15 feet (4.6 m) from muzzle, velocity of 2,940 ft/s (896 m/s) for the 129-grain bullet and 2,690 ft/s (820 m/s) for the 140-grain bullet (which compares to .300 Winchester Magnum data of 2,930 ft/s (893 m/s) for a 200-grain bullet and 2,665 ft/s (812 m/s) for a 210-grain bullet).[2] Long-range shooter Ray 'RayDog' Sanchez summarized the bolt-actionTubb 2000 rifle in 6.5mm Creedmoor as 'boringly accurate' at 1,000 yards (914 m). He asserted the rifle/ammunition combination he used maintained sub-MOA groups at 1,000 yards (914 m).[16]6.5mm Creedmoor can provide sub-half-minute of angle accuracy from factory ammo.
The ability to retain velocity keeps the 6.5mm Creedmoor with 140-grain match bullets in the supersonic range out to around 1,150 yards (1,052 meters), while the .308 Winchester with 168-grain match bullets hits the transonic window at about 975 yards (892 meters). [17]

Handloading[edit]
6.5 Mm Carcano
The longest 140gr bullets reach the neck-shoulder junction. Due to the relatively long neck, it can be reloaded with long target bullets without placing the base of the bullet below the neck. This eliminates the 'donut' problem seen by many cases after being reloaded over 20 times. Left to right: a Remington 140gr and a 123gr A-Max. Calipers are set to magazine length.
Handloading costs for the 6.5mm Creedmoor are roughly-equivalent to other 6.5 mm cartridges, such as the 6.5×47mm Lapua, due to the availability of Lapua small primer brass for both cartridges.[18][19] As of January 2020 Lapua is also manufacturing 6.5 Creedmoor brass with large rifle primers.[20] Norma makes brass for the cartridge, and Norma brass is available through several major-retailers at approximately the same cost as Lapua brass. Lapua brass for 6.5×47 lasts for about 12-to-20 reloads.[21] Starline sells brass cases with either large or small primer pockets, with small pocket brass costing slightly more.[22]
After the 6.5mm Creedmoor was introduced, it was advertised as a 60,000 psi capable case.[7] However, after it was placed into production, Hornady listed it as 62,000 psi, then registered it with SAAMI as such. For this reason, many hand loaders have poor experiences reloading for it. Blown primers on the first shot at 62,000 psi are not uncommon. Early shooting articles listed the ammo as loaded to 58,000 psi,[23] but later citings list it as 57,000 psi.[24] Hornady reduced the loads in its factory ammo because of complaints it was often blowing primers.[25]
Lapua delivered 6.5mm Creedmoor brass at Shot show 2017,[26] and production quantities became available via major retailers in second quarter 2017. The Lapua version has a small primer pocket.[18][27] Thus, load data for small-primer brass are not interchangeable with those for large-primer brass. A smaller diameter decapping rod is required to size and decap. As of January 2020 Lapua also manufactures its brass with large rifle primers addressing concerns that some small rifle primers may not efficiently ignite the powder charge in cold weather conditions causing hang fires or misfires. Large rifle primer Lapua brass also allows the use of a standard size decapping rod.[20]
The 6.5mm Creedmoor as parent case[edit]

The 6mm Creedmoor is a necked-down version of the 6.5mm Creedmoor using 6 mm (.243 inch) bullets, lighter than 6.5 mm bullets with similarly-reduced recoil.[28] John Snow at Outdoor Life designed it in 2009. As of May 2018, Savage Arms offers three bolt action rifles and one semiautomatic rifle chambered in 6mm Creedmoor.[29] As of May 2018, Hornady offers 87-gr Varmint Express, 103-gr Precision Hunter and 108-gr Match ammunition in 6mm Creedmoor.[30]
The 22 Creedmoor is another even further necked-down version of the 6.5mm Creedmoor using 22 (.224 inch) bullets, lighter than 6 mm bullets with even softer recoil.[31] It is easier to rather neck down 6mm Creedmoor brass, or fire forming.22-250 Rem. brass for it, although there are now a number of manufacturers producing brass casings for the 22 Creedmoor caliber.
Military use[edit]
In October 2017, Jixipix grungetastic 2 70 30. U.S. Special Operations Command (USSOCOM) tested the performance of 7.62×51mm NATO (M118LR long-range 7.62×51mm NATO load), .260 Remington, and 6.5mm Creedmoor cartridges out of SR-25, M110A1, and Mk 20 Sniper Support Rifle (SSR) rifles. SOCOM determined 6.5 Creedmoor performed the best, doubling hit-probability at 1,000 m (1,094 yd), increasing effective range by nearly-half, reducing wind drift by a third, with less recoil than 7.62×51mm NATO rounds. Tests showed the .260 Remington and 6.5mm Creedmoor cartridges were similarly accurate and reliable, and the external ballistic behavior was also very-similar. The prevailing attitude is there was more room with the 6.5mm Creedmoor to develop projectiles and loads.[32][33] Because the two cartridges (7.62×51mm NATO and 6.5 mm Creedmoor) have similar dimensions, the same magazines can be used, and a rifle can be converted with just a barrel change. This led to its adoption and fielding by special operations snipers to replace the 7.62×51mm NATO cartridge in their semi-automatic sniper rifles, planned in early 2019. In response to SOCOM's adoption, Department of Homeland Security also decided to adopt the round.[34][35] U.S. Special Operations Command will convert their 7.62×51mm NATO M110 Semi-automatic Sniper rifle (SASS) and Mk 20 Sniper Support Rifle (SSR) rifles to 6.5 Creedmoor in 2019, a process that requires just a new barrel.[36] In 2018, USSOCOM announced they would roll-out 6.5 mm Creedmoor in a long-range precision rifle, and use it in a carbine and assault machine-gun.[37] That means that the US Special Forces will use the same calibre for an assault rifle, light machine gun, and sniper rifle. That will give better penetration and terminal ballistics (because of high sectional density and retained energy), while providing longer range precision fire.
At the National Defense Industry Association’s annual Special Operations Forces Industry Conference (SOFIC), beginning May 20 2019, FN unveiled a prototype of its Mk 48 Mod 2 machine gun chambered in 6.5mm Creedmoor to fill a USSOCOM requirement. American special operations forces are interested in acquiring a lightweight belt-fed 'assault' machine-gun offering better range than existing weapons.[38][39]

The 6.5mm Grendel (6.5×39mm) is an intermediate cartridge designed by Arne Brennan, Bill Alexander and Janne Pohjoispää as a low-recoil, high-accuracy cartridge specifically for the AR-15 platform at medium/long range (200–800 yard). It is an improved variation of the 6.5mm PPC.[4] Since its introduction, it has proven to be a versatile design and is now expanding out into other firearms including bolt-action rifles and the Kalashnikov system.[5]
The name '6.5mm Grendel' was a trademark owned by Alexander Arms until it was legally released to allow the cartridge to become SAAMI standardized.[6][7]
Development and history[edit]
The 6.5mm Grendel design goal was to create an effective 200–800 yard STANAG magazine-length cartridge for the AR-15 that surpassed the performance of the native 5.56mm NATO/.223 Remington cartridge. Constrained by the dimension of the magazines, the Grendel designers decided to use a shorter, larger diameter case for higher powder volume while allowing space for long, streamlined, high-ballistic coefficient (BC) bullets. Firing factory-loaded ammunition with bullets ranging from 90 to 129 grains (5.8 to 8.4 g), its muzzle velocity varies from 2,500 ft/s (760 m/s) with 129- and 130-grain (8.4 g) bullets to 2,900 ft/s (880 m/s) with 90 gr (5.8 g) bullets (similar in velocity to a 5.56 mm 77-grain (5.0 g) round). Depending on their case material and bullet, 6.5 Grendel cartridges weigh 14.7 to 17.8 grams (227 to 275 gr).
The case head diameter of the Grendel is the same as that of the .220 Russian, 7.62×39mm and 6.5mm PPC cases. This diameter is larger than the 5.56×45mm NATO, thereby necessitating the use of a non-standard AR-15 bolt. The increased case diameter results in a small reduction in the capacity of standard size M16/AR-15 magazines. A Grendel magazine with the same dimensions as a 30-round STANAG magazine will hold 26 rounds of 6.5mm Grendel ammunition.
Performance[edit]
C-Products 26-round Grendel Magazine
Proponents assert that the Grendel is a middle ground between the 5.56×45mm NATO and the 7.62×51mm NATO. It retains greater terminal energy at extended ranges than either of these cartridges due to its higher ballistic coefficient.[2] For example, the 123 gr (8.0 g) 6.5 Grendel has more energy and better armor penetration at 1,000 meters than the larger and heavier 147 gr (9.5 g) M80 7.62 NATO round.[8][9][10][11]
In order to obtain ballistics that are superior to the 7.62×51mm cartridge, a weapon with a longer barrel and firing a heavier bullet is necessary. To achieve the same results from shorter length barrels, even heavier bullets are needed.[12]

As noted above, the Grendel case is very closely related to the .220 Russian case. In general, each additional grain of bullet weight will reduce muzzle velocity by 10.8 ft/s (6.1 m/s for each gram) and each additional inch of barrel length will increase muzzle velocity by 20 ft/s (2.4 m/s for each centimeter). Specific details are available as graphs derived from Alexander Arms' public domain load table linked below.
Army and police uses[edit]
Serbia is in process of adopting a rifle made by Zastava Arms[13] in 6.5 mm Grendel caliber as main armament for its armed forces. The rifle, designated M17, is a derivative of the previous-issue M70 rifle.[14] An American-manufactured rifle in 6.5mm Grendel caliber may also be adopted in armament for special forces units after it passes testing in Technical Testing Center.[citation needed] Three types of 6.5mm Grendel ammunition produced by Prvi Partizan Užice Serbia will be tested for use with these rifles.[15][16][17][18][19]
