It can vary from 900-1300 FPS depending on the weight and the firearm. Generally a smaller slug can have a greater velocity and a greater energy.
muzzle velocity is the velocity of bullet and recoil velocity is the velocity of gun.
the muzzle velocity on the 40gn vmax is 2200fps
it is the instantaneous velocity as a projectile leaves the barrel
It depends entirely on the muzzle velocity of the weapon you are using. The higher the muzzle velocity the farther the projectile will travel.
9mm (usually called 9mm Luger or 9mm Parabellum) almost always has a higher muzzle velocity than the 380 ACP (also called the 9mm short, 9mm Kurtz, and 9mm Corto). The two bullets are essentially the same diameter however the 9mm Parabellum is almost always a heavier bullet than the 380 ACP with a larger powder charge and a significantly higher chamber pressure.
Muzzle velocity of the SS-109 cartridge is about 3100 feet per second.
The L1A1 SLR used by the British military is in caliber 7.62 NATO, and has a muzzle velocity of about 2800 fps.
The M4A1 version of the M16 rifle has a muzzle velocity of about 2900 feet per second, firing the 5.56mm cartridge.
The .380 typically has 200-230 pounds of muzzle energy, which is about half the power of a typical 9mm.
