The 6.5mm Creedmoor (6.5×48mm), [6] designated 6.5 Creedmoor by SAAMI, 6,5 Creedmoor by the C.I.P. [4] is a centerfire rifle cartridge introduced by Hornady in 2007. [7]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.
It retains greater terminal energy at extended ranges than either of these cartridges due to its higher ballistic coefficient (BC). [2] For example, the 123 gr (8.0 g) 6.5 mm Grendel bullet has more kinetic energy and better body armor penetration at 1,000 m (1,100 yd) than the larger and heavier 147 gr (9.5 g) bullet of the M80 7.62mm NATO round.
The opposite is true when comparing the .260 Remington to the 6.5mm Creedmoor: They are nearly-identical but the Creedmoor can take a higher chamber pressure than the .260 Remington, leading the Creedmoor to have more room for a longer bullet (more aerodynamically efficient, higher sectional density than most shorter bullets) in a given ...
2,745 ft⋅lbf (3,722 J) The 6.5mm Remington Magnum is a .264 caliber (6.7 mm) belted bottlenecked cartridge introduced in 1966. [2][3] The cartridge is based on a necked down .350 Remington Magnum which on turn is based on a shortened, necked down, blown out .375 H&H Magnum case. [4] The cartridge was one of the first short magnum cartridges.
In 2007, Hornady released the first 6.5mm Creedmoor Cartridge. The 6.5 Creedmoor was a joint development between former Marine Corps competitive shooter David Tubb and Hornady Ballistician David Emary. [11] Hornady Manufactures 6.5 Creedmoor cartridges, bullets and reloading dies.
Other 21st century cartridges, like the 6.5×47mm Lapua and the 6.5mm Creedmoor that have entered the market also are able to provide similar performance to factory 6.5×55mm ammunition. However, the extra case volume of the 6.5×55mm promotes a longer lifespan of the cartridge case when reloading, and will provide higher velocities when ...
Ballistic coefficient. A selection of bullets with different shapes, and hence, different ballistic coefficients. In ballistics, the ballistic coefficient (BC, Cb) of a body is a measure of its ability to overcome air resistance in flight. [1] It is inversely proportional to the negative acceleration: a high number indicates a low negative ...
