Is there any data out there of how a 5.56 FMJBT round reacts through different obstacle (single-pane glass, plywood, etc)

I overheard people talking about how ammo reacts through car windows, etc. at the range, and was wanting to find some hard facts about it.

Thanks

http://www.theboxotruth.com/ has all you need.

And rounds going through windshields from outside deflect very slightly upward. Outbound rounds deflect slightly downward. Well the first one, anyway.
