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.

Light weight non-expanding projectiles pushed at a relatively high rate of speed are also utilized, generally for close ranged applications well inside 100 yards. The light for caliber bullets will transfer energy to a given medium more rapidly, yet with consistent penetration characteristics relative to their sectional density and a constant ...
The cartridge that would become the 300 BLK already had a slow speed with its designated heavy bullets. SOCOM added a noise suppressor, and by lowering the bullet speeds further to below 1,000 feet per second (sub-sonic), a significant lowering of the noise level was achieved, while still meeting the minimum performance requirements.
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.

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 ...
The shooting is done at known distances of 100 to 1000 yards from the firing line depending on the format of the match. Some High Power Rifle matches are shot only at 200 yards, such as sometimes seen during specific M1 Garand matches, and Axis and Allies matches, although they are still shot from various positions (standing, sitting/kneeling ...
