Mike, as you well know, I don't know squat about navy gunnery. I'm just trying to think in practical terms.
I mean, here I am with an AR-15; a real good gun with a ballistic range of 1200-1500 yards, but I'm not gonna pull down on any target unless it's inside 200 yards (preferably way inside). I wasn't no shooter, and even 200 yards was a bitch. But I wasn't that bad; I qualified after all.
Even snipers try to stay inside pb-2 and don't shoot at ballistic max. Getting a hit at range is an honest to gosh Vegas crap shot. The odds exist, but they sure ain't in your favor (at least not in mine).
I understand what you are saying..., but swap that AR-15 for a Barrett 50 and you can hit what you aim at at a much longer range. Why? Heavier round = less ballistic instability. British discovered in 1909 that a 13.5" with a heavier shell and a lower muzzle velocity was much more accurate than their preceeding 12'/50..., and their 15"/42 was one of the most accurate naval guns of the any era (and still holds the record for the longest hit achieved between two moving ships.)
Those 16" Rifles at Oahu were inherently quite accurate, especially with their extremely stable mountings. With the added advantage of prefigured correction tables for everything from wind speed, humidity, temperature, and tidal states; virtually all the "variables" could be removed. The advantage of being rooted to a particular piece of real estate for 20 years is that you can get to know the neighborhood very well. And exactly how to bring down effective fire on anything that is foolish enough to come into your range. That's why nothing ever did. Sorry John..., don't mean to be argumentative. But Coast Artillery is a life-long love of mine and I get frustrated that because it was so good at what it did there are virtually no examples of it in action. As Nelson said, "No sailor but a fool" attacks it.
