Not that I'm telling poor old Vlad anything new but if its hardened metal it certainly can bounce the bullets back at you, and in a disturbingly straight line too.

You either get the bullet right through it.

The bullet splashes to oblivion.

Or you have a potential situation.

I've had soft stuff like 22's, buckshot pellets, and 12 ga slugs come back at me from penetration tests.Hit once by the buckshot, not hard though. 12ga slug missed by a few inches-I heard it buzz past.
