Is there really much difference in velocity due to barrel length in revolvers?
As soon as the bullet is in the barrel, the gas escapes out the crack between the barrel and the cylinder reducing the pressure. I find it hard to believe that there would be much difference in velocity from a 4" barrel to a 7.5 inch.

Have any of you had occasion to test a load in different revolver barrel lengths with a chrono?
