The M82 Barrett fires standard .50 BMG cartridges with a muzzle velocity of about 2799 feet per second. As with all bullets, they begin to slow after leaving the muzzle.
@2800 FPS
Depends on which .50 cal, and which cartidge. If you mean a Barrett Model 82A1 sniper rifle, in .50 BMG, standard ball ammo is ABOUT 2800 fps.
Depending on bullet weight and powder, 650-1000 fps or more.
That is sort of like asking how many miles per hour does 100 horsepower equal. Ft lbs is energy, and FPS is speed. There IS a formula to calculate the energy (in foot lbs) of a bullet, but to use that, you need to know SPEED in FPS, and WEIGHT (in grains) of the bullet. A 40 grain bullet at 1000 fps is pretty weak. A 400 gr bullet at 1000 fps can drop a moose.
In a snail, YES. In a bullet, NO!
The answer is dependant on the load and round. An .22 short cartridge can be under 800 FPS while a .22 LR cartridge can be over 1800 FPS. So it is dependent on the cartridge size, the bullet weight and shape, and the quantity and type of propellant used.
around 3500 fps
in the pistols, the 9mm bullet at 1400 fps and the 44magum at 1600 fps.
It's going to vary between manufacturer's and bullet weights, but avg velocity is around 1050 fps
It depends on a number of factors including propellant charge, bullet weight and barrel length. Handgun muzzle velocities range from about 750 feet per second and 1350 fps. Ordinary rifles go up to about 3,000 fps. Some specialty rounds go above that. For an idea of the variation: using the same 357 Magnum round, a snub-nosed revolver will eject the bullet at 1,100 fps, a match revolver at 1350 fps and a 16" barrel rifle at 1,850 fps. Your standard-issue .45 cal pistol ammo has a muzzle velocity around 850 fps.
65 FPS
Bullets alone have no velocity. The .223 CARTRIDGE, when fired from an M16 rifle, will drive its bullet at about 3,200 fps. However, velocity depends on the makeup of the cartridge (powder charge, bullet weight) , and which firearm it is fired from.
