Please rework the ammunition for the 90mm M3 cannon

In this case all AP rounds should be reworked, at least to save britain(17-pounder my beloved).

Except britain, because british must suffer, lol.

Okay. France must be saved. Drum autoloaders my beloved.

Probably we just need to change the overmatch modifier for sloped armor to buff AP.

So that +850m/s solid AP rounds will penetrate around their caliber thickness of armor at 60°.

If 37mm M74B1 goes from 30 to 39 mm at 60°,
that would bump up 120mm M358 to around 140mm at 60° and 90mm T33 to around 87mm or something like that :P

You don’t need to change the overmatch system. Just use the penetration in WWII ballistics to go along with the slope modifiers already implemented in the game.

For reference, my suggestion puts M77 at 190mm, vs 188mm for WWII Ballistics. T33 is 208mm vs 206mm. M79 is 157mm vs 154mm.

No thank you. I don’t want AP to have impossible 0-40° penetrations.

Why does armor penetration matter now?

It always mattered but we don’t make the rules, ok?

Before the calculators were a thing ,Gaijin intentionally nerfed the T33s flat pen without doing anything about the now terrible sloped pen. The system they use to calculate sloped pen needs to have it’s original data inputed or you’ll get the wrong results.

Besides, Russian APHE still has their uber special slope normalization.

How does AP penning more from 0-40 degrees matter when APC is already over performing across the board? Proper APCR performance would out perform AP from 0-40 degrees anyways.

There is was no “original” data. It was all just calculted data but from WW2 Ballistics: Armor and Gunnery.

A slope modifier only works when you consider “theoretical” penetration values.
At high velocity, AP rounds will deform and have reduced penetration against vertical and near vertical armor.
The whole reason why APC was used, apart from the obvious benefit against face hardened armor.

APC isn’t overperforming across the board. A few rounds penetrating more than they should due to Gaijin only looking at the weight of the shell as a whole, doesn’t compare to practically all AP rounds that would penetrate more 0-40° armor.

APCR and APC fulfill practically the same purpose, to penetrate thick armor plates that you wouldn’t be able to penetrate with AP.

Atm APC is superior to AP because it has more 0° pen while nearly the same slope performance.
That missing 0° should be working extra for +45°. Making AP better against sloped armor.
Hence why a simple adjustment to slope and overmatching modifier would be the simplest solution for proper working AP.

I never liked the whole idea of slope multipliers in the first place. If you are gonna calculate the 0° penetration of all shells, and then estimate their penetration at X° by applying slope multipliers to that estimate, you might as well estimate the sloped penetration directly from shells mass, caliber and speed like you did for 0° values, without introducing another source of possible error with slope multipliers.

Every APC round that I have found reliable data for is over performing in game.

If you can accept M62 APCBC over performing by ~20%, why can’t you accept T33 over performing by about the same?

What so difficult to understand when I say a few vs. practically all?

Pretty sure that the 75mm and 88mm Pzgr. 39 and British APC rounds are pretty spot on.

I’m not saying that some APC rounds that overperform shouldn’t be changed but this has nothing to do with making nearly every AP round overperform.

It’s whataboutism.

It’s not whataboutism. All APC rounds are over performing. Allied testing of PzGr 39/43 put it around 225mm, not 237mm like in game.

Not all AP shattered and deformed.

If the game can ignore AP cap loss and APC deformation, it can do the same for AP. That’s the system they chose.

Oh no. That one German round that penetrates 5% more than it should, of cousre means that all APC rounds overperform.

Do you have the same data for 17pdr APC and 75mm Pzgr. 39?

It’s just nitpicking. You know how many AP rounds in-game overperform 0-30° wise?

Let’s focus on what should be important: APC rounds penetrating more 0-40° armor while AP rounds penetrating more >45°.

It’s not nitpicking. All APC rounds are overperforming to some degree.

Gaijin chose a standard, one size fits all system. The system has to be fairly implemented.

Nice. I was looking for this document for quite some time.

Well, it says BHN ranging from 250 - 325. So depending on the hardness you get different results.

In-game we don’t have some specififed armor hardness and all armor is treated equally.

I understand. I’m just trying to find information using the same standard to eliminate any debate about what constitutes a penetration.

They buffed accuracy of the gun. Some good news.
