Has there been any comparisons on the accuracy of WWII era BBs main guns? For instance, what was dispersion of shells at some given range? Or, at what range could these BBs keep all, or even half, of their shots into the area of another BB? This question is on the inherent accuracy of the guns and not on their fire direction computers. I would think that the various navies had done testing on these weapons before they were adopted. Is this data still available, if so could someone summarize it? Thanks in advance.
