the link posted above is not from a revolver. The revolver info is under the cylinder gap section.
With a cylinder gap of .006 you can see the velocity dies down much faster due to the escaping gasses. You gain about 200 fps from 2" to 6" barrel, and about the same from 6" to 18". the ratio of barrel length to velocity narrows considerably because the longer the bullet is in the barrel the more gasses can escape through the cylinder gap. You don't get that big increase like would from a Thomson or Marlin.
