I don't think that the lubricant in the wad is the sealing agent as much as the over powder wad is by itself. Its measure of effectiveness should be judged by how snug it fits up against the wall of the chamber.
Lubricant might help to a small degree too but it shouldn't be necessary to impregnate the wad with lube as a means of preventing chain fire.
