Alright you keep believing that then… that magically smaller rounds just magic up mass and material out of their ass to “spall more” with.
Keep dreaming.
Also note how you just haven’t thought up a counter to how the HE wrecks a decent quantity of MBTs.
Lucky that 292 is only HE slinger, and it’s always 100% kill etc etc.
And nope, it’s not about the mass why they spall more, you clearly havent encountered thing called overpenetration.
You really think ammunition what goes trough nearly not deforming generates magically more spalling compared ammo what is deformed completely inside tank after pen.
what actually is your argument, because thus far what you’ve essentially proposed is “the mass doesn’t matter” and “152mm doesn’t spall more than 120mm” which is blatantly daft
can you rewrite that because I genuinely don’t understand what you’re trying to say there
I’m guessing (?) that you think that somehow I think a round that doesn’t deform much causes more spalling compared to a round that has completely deformed.
You forget about how what energy isn’t used on actually penetrating the tank is now being expended as said round… splinters, for the want of a better word, inside said tank.
And, of course, there’s more splinters, because it is a larger calibre APFSDS round. I’m not a genius at designing tank rounds, but my understanding is that if you made a shorter and stubbier fin round, your penetration would go down. So assuming the Soviets have complied with gaijin’s magical formula, you’re going to have a round that is either the same length, or longer. A round of larger calibre has a larger cross section. Unless you’d like to propose an alternative.
Larger Cross Section + Longer Round = More Mass
Now, I’m talking about firing at an MBT. For something like an M1128 you’d probably want to fire HE, to avoid overpenetrating as you say. But if I do fire at an MBT, particularly in the front array, that round will probably not overpenetrate. That round will simply go through the armour, and then spall. And because there’s more of a 152mm round than there is of a 120mm round, that would generate more spall, no?
