It appears that this round can drastically improve the performance of any AR-15 weapon chambered to .223/5.56 mm. Superior accuracy, wounding capacity, stopping power and range have made this the preferred round of many special forces operators, and highly desirable as a replacement for the older, Belgian-designed 5.56×45mm SS109/M855 NATO round.
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 ...
In a study conducted by the Army Marksmanship Unit, they found that at a distance of 300 yd (270 m), the M16 achieved a 24 in (610 mm) grouping, and the M4 achieved a 32 in (810 mm) grouping, which dropped to 12 in (300 mm) and 18 in (460 mm) respectively when using match grade ammunition. [95]
HVP shells fired from 5-inch deck guns would travel at Mach 3, half the speed of a railgun but twice the speed of conventional rounds. [10] The rounds would be more expensive than unguided shells but cheaper than missile interceptors, and engage air and missile targets out to 10–30 nautical miles (12–35 mi; 19–56 km). [ 11 ]
In this instance, heavier bullets are loaded in standard ammunition, which reduces muzzle velocity below the speed of sound. As an example, the very common 9×19mm Parabellum standard military round is a 7.5 g (116 gr) bullet at velocities typically around 360 m/s (1,200 ft/s). Subsonic loads for 9×19mm Parabellum commonly use 9.5 g (147 gr ...
According to their 372-page report, the observed hit rate of the predominantly plastic weapon with the unsupported free-floating barrel drops down to a mere 7% at 100 metres when the temperature increases by 30 °C (86 °F) or more, whereas the Bundeswehr required a hit rate of 90% at that distance.

The US military commonly uses 5.56mm bullets, which have a relatively low mass as compared with other bullets (2,6-4,0 grams); however, the speed of these bullets is relatively fast (approximately 850 m/s (2,800 ft/s), placing them in the high velocity category).
The Ameli (abbreviated from the Spanish Ametralladora ligera or "light machine gun") is a 5.56mm light machine gun designed for the Spanish Army (Ejército de Tierra) by the nationally owned and operated Centro de Estudios Técnicos de Materiales Especiales small arms research institute (founded by the Spanish government in 1950).
