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.
Compared to the 6.8×43 mm Special Purpose Cartridge, another round made to have increased stopping power over the 5.56 NATO, the 300 Blackout has different capabilities. The 300 BLK was designed with a specific shorter-range focus to have equal or more energy than the 7.62 Soviet and work reliably with suppressors.
United States Army Special Forces personnel filed battlefield reports lavishly praising the AR-15 and the stopping power of the 5.56 mm cartridge, and pressed for its adoption. [44] The damage caused by the 5.56 mm bullet was originally believed to be caused by "tumbling" due to the slow 1 turn in 14-inch (360 mm) rifling twist rate. [67]
The Taylor knock-out factor, also called Taylor KO factor or TKOF, is a formulaic mathematical approach for evaluating the stopping power of hunting cartridges, developed by John "Pondoro" Taylor in the middle of the 20th century.
The Heckler & Koch HK417 is a battle rifle designed and manufactured by Heckler & Koch. [1]Being the larger caliber version of the Heckler & Koch HK416, and chambered for the 7.62×51mm NATO rifle cartridge, it is intended for use where the penetrative power, stopping power, and range of the 5.56×45mm NATO HK416 would otherwise be insufficient.
Variability reduces the predictive power of a determination of V0. If for example, the v 0 of an armor design is measured to be 1,600 ft/s (490 m/s) with a 9 mm FMJ bullet based on 30 shots, the test is only an estimate of the real v 0 of this armor. The problem is variability.
Bill Wylde of Greenup, Illinois, compared the two cartridges and changed the chamber of the rifle's barrel to a specification he called the .223 Wylde chamber. The chamber is made with the external dimensions and leade angle found in the military 5.56×45mm NATO cartridge and the 0.2240 in (5.69 mm) freebore diameter found in the civilian SAAMI.
The power module contained a 24-volt nickel-cadmium battery, a 0.8 horsepower (0.60 kW) motor, and solid-state electronic controls. Unless the battery was plugged into a vehicle's power supply, the battery's charge would be depleted after 3,000 rounds.
