Varying Shell Weights

[thorthemighty]

Not all shells are created equally. They can vary in weight quite substantially even when in the same caliber which resulted in different performance levels. I propose that the same is integrated here. 

A Quality 0 8in Gun shooting standard projectiles would have the performance as it currently does in game. But this change adds two different shell weights: Light and Heavy; they affect the performance of the gun in different ways. 

A Quality 0 8in Gun shooting Light Shells will result in the gun having less armor penetration but a longer range and higher rate of fire due to reduced weight of the shells on the same powder charge and due to the lighter shell. This would have the advantage at long-range of probably being able to achieve Deck Armor fights, however due to reduced weight the shells don't do as much damage. Additionally they are less accurate than standard shells when fired in situations where a Cross-Wind is involved due to being lighter and thus not quite retaining their velocity as well as standard shells. 

A Quality 0 8in gun shooting Heavy Shells would have somewhat less range and a slightly slower rate of fire, but they make up for it by having higher armor penetration and damage compared to Standard Shells. Additionally they are more accurate in crosswind situations due to having more mass than Standard Shells meaning they retain their velocity better. 

Thoughts?

I would think that with the -1 and +1 it can be somewhat extrapolated that such is already the case as part of it.

I think the problem here isn't so much that -1 to 1 already covers it, but how to make it viable in game without being a-historical
Historically, any shell that was relatively heavy or light compared to its caliber usually performed worse than a standard shell
So you'd basically be choosing an option that's most likely gonna be worse

I'm pretty sure we already have a "super heavy shell" tech which simply increases your armor penetration.

As far as physical effects for shell mass goes and all other things being equal, the following applies in general:
1) heavier shells loose less energy over time
2) lighter shells have higher muzzle velocity, but less energy
3) heavier shells tend to have slightly higher muzzle energy, but are slower
it follows, that
4) speed beats armor, so light shells tend to have higher belt penetration at low to medium ranges
5) lighter shells tend to have longer range, and have a flatter trajectory initially, increasing low to medium hit probability
6) light shells have no appreciable deck penetration at close to medium range
7) heavier shells have more deck penetration
8) heavier shells are less effected by the environment (e.g. wind or rain) but take longer to reach the target at any given range

to toot my own horn a bit something like this might allow for what you want

nws-online.proboards.com/thread/2626/more-depth-gun-customization-system

you can request a 8 inch gun with heavy shells but low velocity
or a 8 inch gun with ridiculous velocity but stuff like accuracy and energy over range decrease

It should be noted that poor Italian accuracy due to **** shells is only a meme, it only happened once or twice. Plus the Italians had a really weird way of measuring dispersion compared to everyone else which gave the impression that they had really bad accuracy.

do you have any source to back up the data for dispersion was only in italian ?
here is an article comparing italian and british guns
www.sociostudies.org/almanac/articles/the_british-italian_performance_in_the_mediterranean_from_the_artillery_perspective/#_ftn1

while the italian quality control really only showed its bad side once in battle it was pretty consistent throughout the battle
on top of this the battle of cape spartivento was in 1940 which gave the italians plenty of time to redo quality control which might have led to better performance later on from the better quality

also a picture of southampton and newcastle taking fire from vittorio veneto showing quite a wide dispersion pattern
