The dispersion is not different between shell types on any ship. HE and AP shells do travel slightly different paths due to differences in shell weight and velocity though, although the ingame simulation of the shell arc does not represent this afaik.

EVERY single ship with 2 amo types - so all DDs, Cruisers and BBs except for RN silver CLs - have different dispersion for each of their amo types

 

Sigma doesn't change. If you had 2.0, you still have 2.0. But that's just your "likelihood to go towards center / consistency", not dispersion itself

"Listed" dispersion - the Horizontal dispersion as it "should" be & is shown to you in wiki / port - doesn't change. This doesn't help much since the value is false anyway, current "working theory" is that this likely is the width for area where 50+% of your shells fill fall, but it's far from being the whole width of your dispersion ellipse.

 

Does your actual Horizontal dispersion change? Noone knows. Maybe. It's still much larger than your listed disp.

So what the does change? Vertical dispersion. The part of the ellipse which is multiple times larger than Horizontal, even if you look at full H. value, not just the listed one. Shells weight and velocity - 2 values you can see changing - are 2 major components of calculating V.disp.. They change, dispersion changes. And that's before we even start looking at "hidden" stats like drag and so on

 

Also as these values change so will your arcs. Generally they will be rather similar, but they really don't have to be. For a very obvious example use NC, shooting at the same range with AP and HE shells. HE arcs are noticeably flatter

With this then your hit chances change aswell. Lower arcs have less chances of going over the target without hitting it

 

The simplified version would be - heavier shell with slower velocity *should* be more accurate (as in - can't go far from target), but a lighter faster shell would have a better chance of hitting (as in - targets shadow (area on water where your shell can't land because the target is in its way) will be significantly larger). Not guaranteed either way ofc, hidden stats can completely change it
