I have never been able to do this, but thought about it several times:
Obtain a laser cartridge that fits the chamber of your gun. Load the "cartridge" with it turned on. Clamp your revolver in a sturdy tripod or other mount, and place a level across the sights so it rests on the top of the rear sight and top of the front sight blade, then level the bubble.(Assuming the sights are aligned with a bullseye at some range) It would be interesting to see where the laser is directed. Note line of sightand line of bore are not parallel.
This after the revolver (or pistol) is sighted in for a particular load.
