Using a ballistic calculator, they determined that a 55-grain bullet would have to be fired at 3,300 ft/s (1,006 m/s) to achieve the 500-yard performance necessary. [ 5 ] Robert Hutton (technical editor of Guns & Ammo magazine [ clarification needed ] ) started development of a powder load to reach the 3,300 ft/s (1,006 m/s) goal.
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 ...
Secondly, when bullets fail to expand as expected, such as an impact on game 50 or 100 yards beyond what the ammunition is designed for, a bullet with a wide enough flat point will never "pencil through" with minimal disruption in the absence of tumbling. A properly proportioned flat pointed bullet can most assuredly leave a hole of sufficient ...
So, the muzzle velocity of a 2-inch (51 mm) barrel is less than that of a 4-inch (100 mm) barrel, which is less than that of a 6-inch (150 mm) barrel. Large naval guns will have high length-to-diameter ratios, ranging between 38:1 to 50:1. This length ratio maximizes the projectile velocity.

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]
The 6.8mm Remington Special Purpose Cartridge (6.8 SPC, 6.8 SPC II or 6.8×43mm) is a rimless bottlenecked intermediate rifle cartridge that was developed by Remington Arms in collaboration with members of the U.S. Army Marksmanship Unit and United States Special Operations Command [6] to possibly replace the 5.56 NATO cartridge in short barreled rifles (SBR) and carbines.
