There are A LOT of inconsistencies in the penetration values of different surfaces/textures (for example glass being stronger than wood..), hesco boxes and concrete not stopping bullets, etc.

The VSS 9mm should receive some love aswell, it has a penetration barely better than a 9mm.... which is far from the real life version of the round :)

After Wobo´s videos releases a lot of people gonna start exploiting these inconsistencies! (videos linked below)
