What is the velocity of a 5.56X45mm NATO round?

The velocity of a 5.56x45mm NATO round is approximately 922 meters per second. This figure reflects the typical muzzle velocity achieved when a round is fired from a rifle chambered for this cartridge, such as the M16 or M4. The high velocity of the 5.56mm round contributes to its flat trajectory and effectiveness at longer ranges, allowing for greater accuracy and less drop over distance.

In terms of other options, while 600 meters per second, 800 meters per second, and 1000 meters per second are velocities that may be associated with various types of ammunition or situations, they do not accurately represent the standard military specification for the 5.56mm round. Understanding the correct velocity is crucial for effective marksmanship, trajectory estimation, and ballistics calculations in field situations.
