Two-Piece Ammunition Case Design Looks Interesting

Interesting ammo is interesting.  Highjak86 takes a look:

Shell Shock Ammunition claims this weighs 50% less than the usual brass rounds, and 2x stronger.  Ejects “cool to touch”, and reloadable.  Sounds great to me.  If it works, then why not!?

Gotta watch yourself around the brass shark and brass bandit guys.  Shameless self promotion ;) I know.

Thoughts?
