POSSIBLY the .14-222. This is a .222 cartridge necked down to .14 caliber. MV is about 4500 fps. The Remington 30-06 Accelerator is a FACTORY loaded saboted 30-06 (.25 caliber bullet) that is close behind it. There have been stories of wildcats that exceed 5000 fps, but at that speed, bullets tend to break apart from the speed of the spin. The extremely high velocity cannon on modern tanks overcome this problem by being smoothbore- no spin on the projectile.
FPS is the measurement of speed in feet per second. Depending on what kind of bullet you are talking about, bullets can travel as fast as 4400 fps. Here are a few examples: 9mm-about 1050 fps. .45ACP-about 900 fps. 5.56mm-about 2700-3300 fps. .50bmg-about 2900 fps.
