The question is not whether the weapon was supposed to be loaded or empty. From reports it was supposed to be loaded with blanks. Since it was a revolver it might have been realistic looking blanks. The actor may not have been allowed to unload and check the rounds since only the armourer is allowed to load and unload the weapon. This was mentioned previously.
