    Let m b and v b stand for the mass and velocity of the bullet, the latter just before hitting the target, and let m t and v t stand for the mass and velocity of the target after being hit. Conservation of momentum requires m b v b = m t v t. Solving for the target's velocity gives v t = m b v b / m t = 0.016 kg × 360 m/s / 77 kg = 0.07 m/s = 0 ...

    The velocity of the cartridge ranges from 2,000 km/h (1,200 mph; 560 m/s; 1,800 ft/s) up to about 4,500 km/h (2,800 mph; 1,200 m/s; 4,100 ft/s). The Swift is a large-cased .224 caliber cartridge and bullet that was created for small game such as prairie dogs, groundhogs, marmots and other vermin (or "varmints" in the

  6. .223 Remington - Wikipedia

    en.wikipedia.org/wiki/.223_Remington

    The specification included a Remington-designed bullet and the use of IMR4475 powder, which resulted in a muzzle velocity of 3,250 ft/s and a chamber pressure of 52,000 psi. [8] In the spring of 1962, Remington submitted the specifications of the .223 Remington to the Sporting Arms and Ammunition Manufacturers' Institute (SAAMI).

  7. Subsonic ammunition - Wikipedia

    en.wikipedia.org/wiki/Subsonic_ammunition

    In this instance, heavier bullets are loaded in standard ammunition, which reduces muzzle velocity below the speed of sound. As an example, the very common 9×19mm Parabellum standard military round is a 7.5 g (116 gr) bullet at velocities typically around 360 m/s (1,200 ft/s). Subsonic loads for 9×19mm Parabellum commonly use 9.5 g (147 gr ...
