What is the muzzle velocity of the M940 round?

• A. 3500 FPS
• B. 3450 FPS
• C. 3400 FPS
• D. 3600 FPS

Answer: (B)

Muzzle velocity is the speed of the projectile as it exits the barrel; for a given round, this is a fixed specification under standard conditions. The M940 round has a published muzzle velocity of 3450 feet per second, a value set by the combination of propellant charge, bullet weight, and barrel length. This exact figure is used in ballistic calculations for trajectory, time of flight, and impact energy. Among the options, 3450 FPS matches the standard published velocity for this round, making it the best choice. The other numbers are simply not the stated velocity and would imply different loading or measurement conditions. Real-world velocities can vary slightly with factors like barrel length and temperature, but the standard specification is 3450 FPS.
