well the thing with the italian 15inch guns is that it depened on the supplyer of the chargers from listening to Drachinifel’s vidieo’s on the itailans in ww2 when he intervied some of the intalian historians on it that was one of the conclustions they came to
Yes it would not be as extreme as irl, but generally the longer the gun, the less accurate it is regardless (its mostly tied to muzzle velocity). Gaijin system assumes perfect quality across armour, shells and machinery etc so the dispersion due to the charges should not be a factor but muzzle velocity/gas interference is still an issue.
The Italian guns are still /50 with a muzzle velocity of either 2854fps or 2789fps, this compares with Bismarck’s ~/51 with a muzzle velocity of just 2690fps (which is still high velocity) or Bayern’s /45 2625fps, and finally Britain’s /42 with 2458fps which sets the records and the 2638fps with supercharges.
As you can probably see based on these guns becoming more and more accurate specifically gas interference from the end of the barrels has the primary impact on dispersion, which the best way to estimate is based on the muzzle velocity of the given shell.
Another example would be the Nelson class with their high velocity (2614) out of a /45 gun which was unsurprisingly considered to be not accurate at all. If you check HK reporters comparison across British, German and American guns you can see the length of the gun in relation to its diameter and muzzle velocity often correlates with worse dispersion.
This is largely conflicting the accuracy of the guns themselves with the accuracy of the FCS which is an entirely different topic. And frankly the second screenshot is a load of waffle, we have the firing data for the US 16/50 MK.7 and its relatively poor, yes the US had very good FCS, that was equal to or better than the British (i’d say in 1938-39 Britain had the cards, then when the Iowa’s came online they took it and then in 46 when Vanguard arrives she then took it back, and then by Korea the Iowa’s have it again).
I’d bet on the Yamato class being similar in terms of poor dispersion and their FCS certainly was left behind by the end of the war.
The KGV’s also were highly accurate guns (Britain designed every gun except for the 16 inch MK.1 for high accuracy, though the 16 and 16.5" superheavy for the G 3 was also designed for high accuracy, its only in 1921-22 when they settle on high velocity that it becomes inaccurate), so things like the 14" and the Lion’s 16" MK.II, III, and IV were also very accurate, but all were less accurate than the 15".
Bismarck I don’t actually know how accurate the guns themselves were, but the FCS was decent enough and probably the writeup is a good summary. Though we do know the shot vs Hood was again, a very lucky shot.
Richelieu is another one that is also frankly just wrong, as built they had neither good dispersion like the Italian guns nor did they have good FCS, the FCS changed after their America refits. Part of this was due to their above average muzzle velocity, and part was due to the interference of having quads, though this is somewhat mitigated by arranging them with a gap in the middle of the turret. This was eventually mitigated by adding delaying coils as dispersion at 29000 yards was in excess of 525 yards without them and 330 yards with them fitted. That is to be frank. Abysmal, the 13.5" gun has a dispersion of 186 yards and that’s less accurate than the 15"
Actually bad dispersion comes from firing procedure and IJN soon fix it. Both gun and FCS were decent enough. Actually much better than Brit/German/French FCS in terms of ‘automatic’
Reverse. It’s firing result on stationary target was very good, but FCS was horrible, almost WW1 level.
I posted data of German guns’ dispersion earlier. 38cm SK/C 34 was one of the most accurate German naval guns, significantly better than the 28cm SK C/34.
On the other hand, In this game 38cm SK/C 34 (already in the game files) shares the worst accuracy as the other 15" and 16" guns, while the irl not so accurate 28cm SK/C 34 has laser gun accuracy in the game.

I thought those were the WW1 guns found on Bayern, in that case then yes another very accurate gun.
Does the Japanese 16.1" have higher dispersion than the 15" on British and German ships or do they all share the same dispersion value?
Same

Thanks,
Sorry to ask again but can you recommend any method of testing lateral dispersion on high calibre guns?
well i always love my shells from the same turret landing the oposite way round or in vertical line i would put some examples but i have not played navel since the event and all my clips have been over written
what in the cursed abomonation is that ship
Iron Duke xd
Man I hoped they would add this refit, would be funny as hell on 6.3 or even 6.0 since they removed majority of its armor together with installing that 114mm and few AAs.

however, it should be vt shell
Iron Duke was a training ship but also used for testing of new armaments. In this case the 5.25" DP.
Looks incredibly out of place missing B and Y turrets.

i am going to point this out they have been refusing to give british BB’s the he-vt round they should have for “balance”
I don’t even know how youd balance this xD. A singular Tiger turret.
Well just for Renown which frankly is BS. Its got nothing to do with balance otherwise why do the other stronger ships have HE-VT. Renown is no more meta than a US standard imho.
Though Renown is the only capital ship we have that can use HE-VT.
