You are right, it leaves the barrel before all the powder can burn. Normally, velocity in a 6" bbl will be higher than a 4" or a 2". This also applies to semi autos. There are exceptions, the gap between the face of the cylinder and the rear of the bbl can cause the velocity to be higher or lower than normal.
