I've seen a chunk from Bert's shrinker.  It was 3/8-1/2" thick angle 
that was bent outwards and had a copper sheen to it.  I think it was 
a support or work coil holder.  The inside looked similar to walls of 
a shaped charge hit.  Building tanks with 1/2" may seem like 
"overkill", but at least you're not getting killed.

5000 fps?  Yipes!!!!  I think grenade fragments are slower!
