BT7: Penetration data?

[Steiner14]

Hello,

i'm interested in the penetration data of the BT-guns. Since i don't have CMBB installed anymore, i hope someone could be so helpful and take a look at the penetration data and post it here?

What can the BT-7 with the

45/L46

75/L17

calibers penetrate

@100 @500 @1000m

@0 degree?

And does it have the same penetration-performance as the T70 (45/L46)?

45/46 100 500 1000

0 63 42 31

30 39 34 30

60 30 25 19

BT-7 1939 , AP

76.2/17 100 500 1000

0 39 36 32

30 36 33 30

60 30 29 27

BT-7A Artillery tank, AP

edit: sigh, learning to preview before posting.. but not how to get the spacing right...

Thank you, very appreciated!

Also though, don't believe the high short range flat number for the 45mm too much. The modeling of 1941 quality Russian ammo is pretty extreme, and I've seen repeated "shell broke up" results where those numbers would imply reliable penetration. E.g. failing continually against 50mm plate at point blank, and even against a Pz II front at 400 meters or so.

Steiner14 - you're welcome.

And for the second part of your question, there does seem to be a discrepancy between the T70 gun and the BT-7 (1mm of penetration at 500m range against 30 degree sloped armour). Given that the two tanks purchased for the same battle have the same penetration characteristics, I would assume that something else is being calculated for - Jason let the cat out of the bag.
