Each round is stuffed with 85 grams of HA41 (hexogen aluminium) or 85 grams of penthrite. The equivalent of the TNT in a stick grenade.
So the Hispano MkII fired both an HEI and SAPI round in a mixed drum or belt. HTC is probably cludgeing them together. So what happens when a semi armor piercing incendiary\ high explosive round lights up on impact a single Type I, 3 cm Minengeschoss? Hexogen aluminum goes off about 1000c with the explosive output of a stick grenade.
Nawwwww, bet Hitech coaded the damage model so you loose a MK103 or get a pilot wound. Wonder how many time a spit pilot got lucky and cooked off the MK108 ammo in a FW190-A8 wing?
