The speed of a bullet depends on many factors, such as the type of firearm, the cartridge, and the length of the barrel

. Most bullets fired from sporting firearms have a speed ranging from 500 fps to a little over 4,000 fps

. The fastest bullets can travel over 2,600 feet per second, which equates to over 1,800 miles per hour

. Several examples of bullet speeds from different firearms include:

• Black powder muskets Muzzle velocities range from approximately 120 m/s (390 ft/s) to 370 m/s (1,200 ft/s)

• Modern rifles Modern rifles with high-velocity cartridges such as the .220 Swift and .204 Ruger can reach speeds of more than 1,200 m/s (3,900 ft/s)

• Tank guns Tank guns that fire kinetic energy penetrator ammunition can reach speeds of 1,700 m/s (5,600 ft/s)

• Remington 223 Can leave the muzzle at speeds of up to 2,727 mph (4,390 km/h)

• 9mm Luger Can reach speeds of up to 1,360 mph (2,200 km/h)

• AK-47 Has a muzzle velocity of about 1,600 mph (2,580 km/hr)

• Winchester Swift hunting rifle Fires a 5.6 mm bullet at 1,253 m/s or 4,510 km an hour
