Just to clarify, the diameter of the bore is given in inches (eg. 4") and the length of the barrel in calibres (multiples of the bore diameter).
So a 4"x50calibre weapon had a chamber bore of 4 inches, and a barrel length of 200 inches (or 16 and 2/3rds feet).
And I've read that they used them a fair bit, especially towards the end of the war when large, torpedo-worthy targets were few and far between. A number of sub skippers shelled junks and near shore barge traffic a lot.
