Using a ballistic calculator, they determined that a 55-grain bullet would have to be fired at 3,300 ft/s (1,006 m/s) to achieve the 500-yard performance necessary. [ 5 ] Robert Hutton (technical editor of Guns & Ammo magazine [ clarification needed ] ) started development of a powder load to reach the 3,300 ft/s (1,006 m/s) goal.
The 5.56 mm round had to penetrate a standard U.S. helmet at 500 yards (460 meters) and retain a velocity over the speed of sound while matching or exceeding the wounding ability of the .30 carbine cartridge. [50] This request ultimately resulted in the development of a scaled-down version of the Armalite AR-10, named the ArmaLite AR-15. [51]
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.

[citation needed] The cartridge fits single-stacked in a standard AR-15 magazine with a single-stack ...

For example, in Denmark rifle ammunition used for hunting the largest types of game there such as red deer must have a kinetic energy E 100 (i.e.: at 100 m (110 yd) range) of at least 2,700 J (2,000 ft⋅lbf) and a bullet mass of at least 9 g (140 gr) or alternatively an E 100 of at least 2,000 J (1,500 ft⋅lbf) and a bullet mass of at least ...

They also have a new modified gas system designed to reduce barrel vibration [14] and can shoot two-inch groups at 100 yards, which is 2 minute of angle (MOA) accuracy. [ 16 ] Around 2007 or 2008, Ruger added a heavier, larger-diameter barrel visibly tapered from gas block to muzzle.
