SIZE MATTERS | Super ISU-152-2 vs TIGER II | 152mm BL-10 Armour Penetration Simulation

The ISU-152-2 was a prototype tank destroyer from WWII, armed with one of the most powerful tank cannons in history, the 152mm BL-10.
Compared to the standard ISU-152's gun/howitzer, which was already considered a "beast slayer", the BL-10 launched its AP projectiles with around DOUBLE the kinetic energy.
In the simulation, the Tiger II's UFP had been modelled as good quality 240BHN rolled homogenous armour (RHA). The BR-540B armour piercing high explosive ballistic cap (APHEBC) projectile has been modelled to follow the hardening profile of similar Soviet rounds of the era (250-300BHN lower body progressing up to ~450BHN at the nose).
It should be noted that various sources provide conflicting information on the muzzle velocity, with it being taken as 850m/s for the simulation. The range of 750m was derived from this muzzle velocity.
Also, while 150mm @50° 750m may seem more than the experimental ~200mm @0° 1000m, the penetration criteria is much different, with the experimental data requiring a significant amount of the projectile's mass to pass through the target. (which evidently would require a lot less than 150mm @50° to happen, as nearly none passes through in the simulation)
