The distance a bullet will travel is almost completely dependent on the size/weight of the bullet, and the velocity of the bullet as it exits the end of the barrel. For instance, an average .22 caliber bullet shot from a revolver with an average barrel length (12.7 cm) can easily travel one kilometer and still be relatively accurate, and -- if the angle the gun was pointed and other given conditions are right -- up to two kilometers. Generally speaking, the larger caliber the bullet, and the smaller the exiting velocity, the slower -- and therefore shorter distance -- the bullet will travel.
If you are asking for an effective kill distance for a revolver, that will predominantly depend on your skill with said revolver. If you can accurately shoot up to 200 meters with the revolver, then that is your effective kill distance. If you are only accurate up to 5 meters away, then that is your effective kill distance. The average individual with minimal training can typically hit 80% of shots taken on a body-sized silhouette at 20 meters.

You can shoot them in a .357 Magnum revolver, but that's about it.
The presently manufactured Taurus "Judge" in its many variations fits that bill in .410.
The difference is that a pistol has a magazine and a revolver has a rotating cylinder that has individual chambers to shoot
