6mm

The 6.5mm Creedmoor, designated 6.5 Creedmoor by SAAMI, 6,5 Creedmoor by the C.I.P. or 6.5 CM or 6.5 CRDMR for short, is a centerfire rifle cartridge introduced by Hornady in 2007 as a modification of the 6.5 Carcano and the .30 TC, and is based on the .308 Winchester. 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. The cartridge was designed specifically for long-range target shooting, although it has success in game hunting. 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.
