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 ...
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.
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 .204 Ruger has proven to be a very accurate and efficient cartridge: an early tester reported 1/2 MOA groups at 100 yards (91 m) with the Hornady loads and a Ruger No. 1 varmint rifle. The first cartridge in the family, the .222 Remington, was a top benchrest shooting cartridge for many years after its introduction.
Muzzle velocity: M193: 965 m/s (3,166 ft/s) SS109: 925 m/s (3,034.8 ft/s) Effective firing range: 250–400 m sight adjustments: Maximum firing range: 450 m (492 yd) Feed system: 30-round detachable STANAG box magazine (standard issue) or other STANAG magazines: Sights: Rear flip aperture, front post 513 mm (20.2 in) sight radius (standard rifle)
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.

Its light recoil, high velocity, and flat trajectory allow shooters to take headshots out to 300 meters. [172] [173] Newer M16s use the newer M855 cartridge increasing their effective range to 600 meters. [128] They are also more accurate than their predecessors and are capable of shooting 1–3 inch groups at 100 yards.
