Wrong Bursting Charge in British 343 mm and 305 shell

United Kingdom / Britain 13.5"/45 (34.3 cm) Mark V - NavWeaps 343

CPC - 117.4 lbs. (53.3 kg) Black Powder not tnt

United Kingdom / Britain 12"/45 (30.5 cm) Mark X - NavWeaps 305

APC and CP were black powder filled while HE was lyddite filled. When the war started the outfit was increased to 110 rounds per gun in most ships. At the time when 4crh projectiles were issued to the Invincible class, the outfit was 33 APC, which were lyddite and black powder filled, 38 CPC and 39 HE.

CPC only Black Powder not TNT. They don’t use TNT

15-inch (38.1 cm) Mark I - NavWeaps 381

CPC: 129.3 lbs. (58.6 kg) Originally Black Powder, later TNT not 61.67 kg
Barham as 1916 ship will have with Black powder

So, the semi-armor-piercing shell is significantly stronger than it should be. Why does no one correct this obvious mistake?
British large-caliber shells in the game are much better than they were in reality, whereas the German ones are nerfed — at least in terms of armor penetration.

Are you use USN Empirical Armor Penetration Formula?

Black powder does not exist in this game so TNT was used as a placeholder. The parameters of 15" CPC given by Navweaps are wrong. Instead we took figures from original documents and manuals.
