Depends upon charge, barrel length etc, and how far from the muzzle you're measuring it. But around 700 fps is probably a reasonable guess.
Depending on bullet weight and powder, 650-1000 fps or more.
fill it all the way up get 1000 fps no worry about blowing up
around 3500 fps
It all depends on the length of the barrel, the caliber, and how much blackpowder you pour down the barrel. A pistol, which is a single shot muzzleloading handgun was around .50 cal and loading 40 grains of blackpowder and a patched round ball shoots at around 750 fps. A revolver, such as the .44 cal Colts and the .44 cal 1858 Remingtons used during the Civil War loaded around 35 grains of blackpowder with a slightly oversized ball, around .451 or .454, can spit those balls at around 800+ fps. The 1847 Colt Walker was a .44 cal open top revolver, but on a much bigger frame. The gun loaded weighed a good five pounds, and it had a larger and long cylinder which held more powder, and could spit roundballs at over 1200 fps. The black powder Colt Walker is regarded as the most powerful commercially manufactured repeating handgun from 1847 until the introduction of the .357 Magnum in 1935, and has a muzzle energy nearly exactly the same as a 4-inch-barreled handgun firing a .357 Magnum.
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.
Gamo Hunter Extreme 1650 FPS - Air rifle .177 Cal Air Force TalonP 900 FPS air pistol .25 Cal Hatsan AT P1 Air Pistol .177 870 FPS The Air Force TalonP is faster in .25 Cal than the Hatsan .177 Cal
That will depend on WHICH .38 caliber cartridge (thre are several) the length of the barrel (longer barrels= faster bullets) and the catridge itself. A very light target cartridge will be slower than a hot defensive cartridge. For a .38 Special revolver with a 4 inch barrel, velocity averages about 770 fps, but may range from 670-980 FPS.

@ 4000 fps or so
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.
In .22 cal it's rated at 1000 FPS
