Barrett claims that this cartridge is capable of propelling a 398 gr solid brass boattail spitzer bullet out of the 32-inch (810 mm) barrel of a Model 99 single-shot rifle at 960 m/s (3,150 ft/s), giving it a ballistic coefficient of .720, and keeping the projectile supersonic out to 1,737 meters (1,900 yards, ~1.2 miles).

The M16 rifle (officially designated Rifle, Caliber 5.56 mm, M16) is a family of assault rifles adapted from the ArmaLite AR-15 rifle for the United States military. The original M16 rifle was a 5.56×45mm automatic rifle with a 20-round magazine.
Most VLD bullets are used in rifles. VLD bullets typically have a ballistic coefficient greater than 0.5, although the threshold is undefined. [1] Bullets with a lower drag coefficient decelerate less rapidly. A low drag coefficient flattens the projectile's trajectory and also markedly decreases the lateral drift caused by crosswinds. The ...
The average ballistic coefficient of the 419 grain (27.15 g) is 0.945 over 3,825 yards (3,500 m). Jamison International stated the G1 BC of this bullet on their websitein 2009 at 0.940. Currently (2024) the average ballistic coefficient of the 419 grain (27.15 g) is stated by CheyTac USA at 0.949 over 3,500 yards (3,200 m).
In ballistics, the ballistic coefficient (BC, C b) 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 acceleration—the drag on the body is small in proportion to its mass.
A guide to the recoil from the cartridge, and an indicator of bullet penetration potential. The .30-06 Springfield (at 2.064 lbf-s) is considered the upper limit for tolerable recoil for inexperienced rifle shooters.

Assault rifles are full-length, select fire rifles that are chambered for an intermediate-power rifle cartridge that use a detachable magazine. Assault rifles are currently the standard service rifles in most modern militaries. Some rifles listed below, such as the AR-15, also come in semi-auto models that would not belong under the term ...
Battle rifles are full-length, semi-automatic or select fire rifles that are chambered for a full-power rifle cartridge, [1] and have been adopted by a nation's military. The difference between a battle rifle and a designated marksman rifle is often only one of terminology with modifications to the trigger and accuracy enhancements; many of the weapons below are currently still in use and have ...
