They often have a caliber comparable to or greater than 7.5 mm (0.30 in) and a maximum effective range of at least 800 m (870 yd), [1] and are intended for engaging targets (large game animals) beyond 300 m (330 yd). However, cartridges with calibers as narrow as 6.5 mm (0.26 in) have been described as being a full-power rifle cartridge.

These cartridges offer better ballistic performance and greater effective range than the 7.62×51mm. Though they are not as powerful as .50 caliber cartridges, rifles chambered for these cartridges are not as heavy as those chambered for .50 caliber ammunition, and are significantly more powerful than rifles chambered for 7.62×51mm.

M24 sniper rifle, equipped with an AN/PVS-10 Sniper Night Sight (SNS) [9] Maximum effective range is given as 800 meters (875 yd), but record shots have been made with the M24 at over 1,000 meters (1,094 yd). Meanwhile, the standard optical sight has a maximum elevation adjustment of 1,000 meters (1,094 yd). M24 SWS system components (U.S. Army ...

According to the U.S. Navy this ammunition should increase the maximum effective range of .300 Winchester Magnum sniper rifle systems to 1,500 yards (1,370 m), decrease wind deflection on bullets in flight and use Hodgdon H1000, a reduced muzzle flash propellant that remains temperature stable across an operational temperature range of −25 ...
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.
With the improved ballistic coefficient – (G1 BC) of approximately 0.321 to 0.337 (ballistic coefficients are somewhat debatable) – of the new bullet, the 1903 pattern cartridge had an improved maximum effective range and a flatter trajectory, and was therefore less critical of range estimation compared to the M/88 cartridge.
