Barrel Wear

United States Battleships, 1935-92 by William Garzke and Robert Dulin (revised edition) :

Quote:
Page 139 : During her Vietnam service, the battleship [USS New Jersey] fired some 6,222 rounds of 16-inch ammunition, both full and reduced charges at both low and high rates of fire. Despite this unprecedented firing for such heavy guns, it was calculated that approximately 55 percent of the barrel life remained, eloquent testimony indeed to the effectiveness of the [Swedish] additive in reducing bore wear
