I believe you misunderstood - I was not replying to you about the weight costs for the turrets of a King George V-style battleship, I was replying to you regarding the supposed danger of quad turrets.
Here is a description of how the guns were loaded with the problem identified.
Propellant bags were transported from their storage locations in the magazines on roller chutes into hydraulically operated cages that raised them to the handling room. A and B mountings had four cages, but Y turret had two. Y turret had two double-door scuttles in place of the other two hoists, primarily because of the reduced vertical spacing for this mounting. In the handling rooms, bags were manually rolled or slid over to open waiting trays from which they were then manually carried to cordite hoppers. There was one hopper per gun on a circular platform connected to the hoist trunk. Power-rotated scuttles and chain rammers transferred the bags to the lower hoist cage. This cage had two compartments which each held two propellant bags (half charge).
Projectiles were moved from the shell rooms by overhead trolleys and then rammed over hinged shell trays through openings normally closed by watertight doors to the revolving shell ring in the shell handling room. The shell rings for the quad mountings held 16 trays in four groups spaced 90 degrees apart while the twin mounting had 8 trays in four groups spaced 90 degrees apart. The shell room ring could either be coupled to the ship or to the revolving stalk. When coupled to the ship, the shell ring was driven by a 24 bhp hydraulic engine that was connected via a flexible coupling, friction clutch, worm gear and pinions with allowance for eccentricity and a rise and fall of up to 1 inch (25 mm) of the ring in relationship to the mounting. When coupled to the stalk, a similar hydraulic engine was used but the connection to the shell ring did not have any provision for eccentricity or relative motion. [Editor's note: This ring proved not to be flexible enough to withstand the twisting of the ship as it moved through the waves or made sharp maneuvers and was a source of jamming] Projectiles were rammed into the upper hoist cage when the ring was coupled to the stalk.
The lower hoists were operated by winches having two reel drums of different diameters on the same shaft which meant that the propellant and shell cages arrived together at the working chamber below the gunhouse. Projectiles and propellant bags were rammed from the cages into traverses which ran on rails across the chamber to the gun loading hoist cage. This was a three level container with the shell on top and half charges in each of the two lower compartments. The hoist then ran up to the gunhouse at a slant such that the loading cages were at the +5 degree loading angle when they reached the gun breeches. After the shell was rammed, the cage incremented upwards twice as the half charges were rammed.
Magazines were located below the shell rooms.

In the actual final event against Bismarck, Rodney fired more shots than KG V did which is interesting.
I favor triple turrets and spaced out secondary turrets.
