Ive seen a helmet made with this stuff and it had been shot with a .50cal and there was barely a dent!
You get hit in the noggin with a 50 cal, it doesn’t matter if the helmet stops the round because the impact force alone will more than likely snap your neck.
I get what you are saying, but what impressed me was that it didn’t go through the material. I’m sure there are uses for something like that!
