The 6.5mm Creedmoor is a centerfire rifle cartridge introduced by Hornady in 2007 as a modification of the .30 TC. It was designed specifically for rifle target shooting competition although it is also achieving success in hunting. Bullet for bullet it achieves a slower muzzle velocity than longer cartridges such as the 6.5-284 Norma or magnums such as the 6.5mm Remington Magnum. However, due to its 2.825 inch overall length, the 6.5mm Creedmoor is capable of being chambered in short-action bolt rifles and AR-10 rifles.
6.5 mm (.264") bullets, in general, are known for their relatively high sectional density and ballistic coefficients, and have seen success in rifle competition. For some loads the 6.5mm Creedmoor is capable of duplicating the muzzle velocity or trajectory of the .300 Winchester Magnum while generating significantly lower recoil, based on lighter projectile weight. As this cartridge is designed for a bolt face diameter of .473 inches (roughly 12 mm), conversion of a short action rifle to it from 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.
This is a medium power cartridge comparable to the .260 Remington and 6.5x47mm Lapua. Three hundred yard energy using 129 grain Hornady SST bullets is listed by an independent reviewer as 1641 ft. lbs. For the 140 grain bullet at 2700 feet per second initial velocity another reviewer reports an MPBR of 265 yards and reports a manufacturer claim of "almost 1600 ft. lbs." of retained energy at 300 yards using a 24 inch barrel SAAMI test data confirms 6.5 mm Creedmoor (fifteen foot from muzzle) velocity of 2,940 fps for the 129 grain bullet and 2,690 for the 140 grain bullet (which compares to .300 Winchester magnum data of 2,930 fps for a 200 grain bullet and 2,665 fps for a 210 grain bullet). Long-range shooter Ray "RayDog" Sanchez summarised the bolt-action Tubb 2000 rifle in 6.5mm Creedmoor as "boringly accurate" at 914 metres. He asserted the rifle and ammunition combination he used was able to maintain sub-MOA groups at over 900 meter distances.
