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]
It appears that this round can drastically improve the performance of any AR-15 weapon chambered to .223/5.56 mm.

For projectiles in unpowered flight, its velocity is highest at leaving the muzzle and drops off steadily because of air resistance.Projectiles traveling less than the speed of sound (about 340 m/s (1,100 ft/s) in dry air at sea level) are subsonic, while those traveling faster are supersonic and thus can travel a substantial distance and even hit a target before a nearby observer hears the ...
For this, following a qualifying shoot, competitors shoot 10 shots at each of 300, 500 and 600 yards, followed by 15 at 900 and 1000 yards for the top 100 scorers after the short ranges. Fullbore target rifle also features in the Commonwealth Games shooting events with both individual and pairs events using the Kings Prize format.
Subdued tracers burn at full brightness after a hundred or more yards to avoid giving away the gunner's position. Dim tracers burn very dimly but are clearly visible through night-vision equipment.
