To clarify, by model above I mean the model I wrote. And BMP-2 2A42 again fits the data and the game data - with a small nuance which I'll address later in the wrap-up (3UBR8 penetration @1.5km). What it looks to me is that the recent APFSDS ammunition has lower drag which can be represented by giving higher sabot range values in OOBs, just as I suspected in the first message.

I'll make a proper post with findings and sources listed later.
