So? The 28 cm/52 (11") SK C/28 used on the Lützow weighed 600mt, the 38 cm/52 (14.96") SK C/34 used on the Bismarck weighed 1052 and the 40.6 cm/52 (16") SK C/34 intended for the H39(?) weighed 1,475 mt.
Throw that at your calculator and can guestimate the weight of a 20" turret. About 2716mt in case you're wondering.
Compare that to the 782mt BL 15" Mk 1 used on the Erebus class.

There's no such thing as "nothing left to draw" If you can down 10 pints and draw, you're doing alright by my standards

I got the gun from a parts-sheet.

@rodondo: guns and all are parts and should not be credited. not even when the gun is half the ship.
also: this turret won't even fit in this arrangement, the deck penetration is at least 5-6 decks

I am editing her not what should I do?

Like I said, make it a lot bigger or use a much smaller gun.

How big a Gun?

Depends on how big a ship you want. British monitors were armed with 12 or 15" twins, though the M15 and M29 classes had far lighter armament and the Lord Clive was armed with a single 18" gun.

What exactly is it meant to be shelling would help.

Ah thanks for clarifying that. I somehow imagine the barbette and the magazine jutting out from the bottom and running ground every day
