THE NAVAL INSTITUTE GUIDE TO WORLD NAVAL WEAPONS SYSTEMS by Norman Friedman :

page 285 : When the [16-inch] guns were brought back into service, there were initial problems with powder, i.e. with the consistency of fire on a round-to-round basis. The problem is reflected in variations in muzzle velocity. Powder of the WW2 era was expected to produce a variation of no more than plus or minus 10 ft/sec; service figures were plus or minus 5 ft/sec. During the Korean War, typical figures were plus or minus 14 ft/sec, and during operations off Lebanon, this deteriorated to plus or minus 32 ft/sec. The reworking program restores the powder to the original standard of plus or minus 10 ft/sec. Existing powder supplies were reblended during 1986 to improve the gun's accuracy.
