!You have claimed so many stupid issues about german ships, Bismarck at her last fight and SH ( Scharnhorst at North Cap) that I'm very tired to mention it all. You have even claimed that the GB 14"/45 Mark VII is less powerfull then the USA 12"/50 Mark 8, what is totaly ridiculous!
Alone from the physiks it is impossible but you can look here------------->

Do some research and get some information and one hint, you should read less victory historical books, that would help very much to improve your historical knowledge
These are the facts Kurfurst, which even you cannot deny. The Scharnhorsts defensive scheme was defeated by the 14/45 guns of the DOY, including the turrets of the German ship. I dont really care if the main belt was penetrated or not....I happen to think it was penetrated, you obviously think otherwise....all i know is that a shell of lesser power than the 12/50 was able to defeat the Scharnhorst defences, relatively easily. You and any body else can argue all day about the alleged invincibility of these armouring schemes, but in the cold hard light of day the armouring schemes of these ships were not enough to save them. If the Scharnhorst could not withstand the effects of the 14/45 at those ranges, it would not have been able to withstand the effects of the 12/50, with the heavier shell and superior AP capabilities. This is because the 12/50 with Mark 18 shell was superior in AP qualities to the guns actually used to sink the Scharnhorst

These also are the facts...at 18000 yards, the 12/50 with Mk 18 shell can penetrate about 14 inches of armour plate. Thats enough to penetrate your 350 mm main belt. At that same range the 28cm weapon can penetratre about 8.8 inches of plate, which is not quite enough to assure penetration of the main belt. This is exactly the same situation as the Bismarck....the British BBs had enough power to get to the vitals of the ship, though not the citadel. It was enough to knock the ship out easily and quickly. And there is no reason to suggest that the the higher powered 12 inch round would not have the samer effect.
You should rethink your statement.And for the record, Bismarck was silenced very quickly in her last battle, taking less than an hour to be silenced. Though her hull was well protected, her combat capability was knocked out with relative ease in her last fight. So much for the uber defences of the German Battleships.......
...If we take it very konservativ and KGV and Rodney shot only one full salvo per minute, then we have 19 shells per minute that were shot to Bismarck. 10 minutes 190 shells, 20 minute 380 shells, 30 minutes 570 shells, 40 minutes 760 shells.
Also Bismarck was disabled (control surface at 45 degree) and could only steer by her shafts with 9kn.
Ideal condition for a target practise.

I don't understand why the German admiral chose to attack in such bad weather. Why not wait until the Luftwaffe could assist?
The whole North Cape szenario was exceptional.
Scharnhorst turned off her Radar to make no radar emission, with the hope nobody would detect her.
With a turned on radar, DoY had never ever had the chance to quit the battledistance to 12000y.
Scharnhorst was totaly taken by suprise.
With the knowledge from today, the decision to turn of the radar was simply rubbish.

MHO not very conservative estimate, you forgot that fairly many barrels missed plenty of salvos, there are info on that for ex. in the naval weapons site.
