What you describe wasn't the fault of the ship, its arms, or even the powder, but the hideously poor state of training which the crews had when the battle wagons were re-introduced. Unfortunately, Navy brass wouldn't like them any more were they put back into the service of America one more time.
(By the time of the Gulf War, however, the bugs had been worked out of both ships and crews and these dreadnaughts were used to awesome effect)

As anyone who's shot competitively can tell you, consistency is the mother of accuracy. You literally could not predict the muzzle velocity of the round from one salvo to the next with the blended powder, and the only lot that wasn't screwed up was used up from 1982 to 1991.
