Japanese ammunition - current vs correct

I made this to illustrate the vast differences between the current and correct ammunition types used by the Japanese planes.

Very Interesting

 

the 30mm and a single P shell by belts to clean the canon when first shot.

 

And also the 12.7 & 13.2mm having HE rounds , also the Ho5 variety of AP for different targets soft/medium/hard or the HE variety for type 99 20mm

 

Didn't the 57mm had AP rounds or something to deal with the ground ? 

 

ps: Only one 37mm had AP rounds :/

Nice work. I'd submit this to the devs with a tiny bit more clarification of what you are giving them. One sentence isn't really enough.

 

The bug report that I submitted was done in June. Hiromachi reported this well before I even did

 

Gaijin definitely knows about this

Fantastic.  Looking forward to the machine-gun calibre HE rounds.  (It'd be even better if they did full damage.)

From what I have read, the Japanese had incendiary and high explosive rounds as the main composition of their ammunition belts to offset the low muzzle velocity and ROF the weapons had

And they just had more of an affinity for explosive ammunition.  Their tank calibre shells had a far higher explosive yield to other nations' as well; used both a greater weight of explosive filling and more effective explosives.

I've heard good things about the AP-I from the Type 99, but the actual ammo belt whit that is hard to use (any tracer or only 1/6).

Could be a good thing a Air targets ammo whit AP-I, HEFI-T or something similar and historical.



In 1,43 Lassar said that the MG HE ammo will work. Edited by Angel24Marin

This is why I firmly believe there should be a weapon/ammunition subsection of the forums just like the aircraft data sheets. So people can figure what source material Gaijin is pulling this stuff from

Wow! Excellent info, SubRyan. Very informative. :salute:

 

Glad to hear Gaijin is aware of this, too. Here's hoping they're making the necessary corrections and we'll see them in 1.43.

 

I agree there should be a forum section specifically for weapons and ammunition. There's so much info that's unique to each country.

From Lassar's Q/A thread :

& also this :

I think we can say bye bye to hopes about P shells and some others ...

 

PS: for the sub forum he said he will see if possible.

The sub-forum would be pointless now if he thinks the Japanese ammo is correct

Unfortunately it is looking like the developers are never going to fix any of these

Why the HE ammo in game is called HEF?

As far I know the Russian HEF is a bullet whit explosive and fragmentation grooves on shell, but the blueprints of Japanese 20mm don't show that.
May is because not is Minengeschop and them have a thicker coating, causing more frag? Or because the air compression fuze break the nose doing shrapnel?

Shhhh... Japanese 20mm now wrecks everything it touches in a single burst.  Fuselages, tails, PBY wings... anything that I touch, it dies.  

 

I hate to sound defeatist but I don't know how any changes would improve things.

I want the Japanese omnipurpose ammo on type 99 gun ti should rekt everything without problem.

I still have lot of issues issues with almost all HE ammos, the thing is that many DM are still messed up and you can cut a wing or entire tail easily with the proper ammos hitting the good spot, the ammos according to Lassar last answers yesterday are still fubar and my guess is that we have again more fragile DM's to mask this ... Maybe more easy to notice for me playing in AB where you can engage a lot more of enemies and usually do more kills in a match .
