Is overpressure realistic?

[QTip_44]

@Bstgunner

How does a Hesh round thats hits an external roadwheel, blow up, go through a 30mm roadwheel, 30mm suspension part, 30mm thick track overhead, followed by a 40mm armour plate overhead end up inside the tank where it then proceeds to go through a not 1 but 2 20mm thick internal armour plates, an engine the size of fiat 500 and part of a huge transmission kiling the driver and machine gunner up there? Like what?

An m44 hit the TIP of my Chi-To-Late barrel (head on) and “overpresured” me without contacting hull or turret.

Overpressure is definitely broken.
