The tricky part, though, is that they were designed to be accurate of "minute of battleship." Which is to say 50% of the rounds will hit an ellipse 400' x 100' at a distance of 16-18 miles (a scant 33,000 yards). Which means if you are a 300'x65' destroyer, you have middling good odds for dodging "between the raindrops" as it were.
Mind you, those APC rounds are designed to cut through 16-18" of armor before the fuze detonates the bare 200# of explosive in the base of the round--so, your 1/2" - 1" plated Destroyer might not even set one off--which is not much consolation if the round trundles through the 1/3 of a destroyer that is the powerplant spaces. Or, if you've made the BB people real mad, and they demonstrate the recursive probability that occurs by adding additional rifles to the mix. (For you curious types, it's factorial of the number of barrels fired multiplied by the accuracy of the firing solution--four barrels fired on an 80% accurate solution gives you a 4! * 0.8 better CEP.)
Good stats.
As a sailor (albeit a retired submariner), the problem with "dodging" anything being delivered as a bombardment is not knowing exactly where the next shell, out of a great many, is going to land. Nine turrents of three barrels, each with the capability of firing two rounds a minute for days on end, is a truely awesome amount of firepower to levy against any target, moving or not. (Your "additional rifles".) Especially when you consider the modern upgrades that were introduced in the 1980s, which tracked muzzel velocities of each round and tracked and targeted with modern radar and computers of the time. As the guns sequenced their shots, you'd be talking about one shell every 3 seconds...hour after hour, day after day.
The fuzing of the rounds with respect to thinner hulled ships is an interesting point. It might be interesting, however, for people who've never given thought to the destructive capabilities of even a non-explosive high velocity round to look up the old naval term "shiver"...as in "shiver me timbers".
Back before the days of explosive projectiles in naval guns, the majority of ship damage was caused literally by a massive cannonball smashing it's way through whatever it hit. And when it hit something like a ship's mast, or penetrated the hull or bulkheads, the wood would "shiver"...meaning it would explode into wooden shrapnel. An entire compartment of men could be shreded this way by a cannonball blowing through a bulkhead...or successive bulkheads. This in addition to whatever direct damage the cannonball did by impact.
Much the same would happen on modern naval vessels when you would blow a one ton hunk of metal through a ship at velocities in the neighborhood of 2,500 fps. Every space not directly impacted by the round as it passed through would be utterly devoid of human life anyway due to secondary effects similar to "shivering" on the old wooden ships.
And, as a side note for the interested, keep in mind what the original design concept of the battleship was: to be able to duke it out against other battleships, as in broadside combat. These ships were massively armored to be able to go toe-to-toe with other battleships...and survive.
This capability was somewhat muted with the advent of submarine and air warfare, and the role of the battleship changed accordingly. As a naval shore bombardment platform, it's one of the most scary things an enemy can see parked off its shores.
