Didn't hardly slow down.

I had asked Tman to bring his AR15, but told him, "I guess it's kind of anti-climatic to shoot a rifle at this stuff."

He said, "Well, it's called AR15.com for a reason."

I guess he was right. So here he is, shooting at about 40 yards.

It went right through, like a hot knife through butter.

Here's a picture of the back side of the plate.

Not really any "spalling" from this stuff.

But the bullets were still zinging along.

Lessons learned:
1. There's bullet-proof and then there's not-so-bullet-proof. This stuff stopped a .22LR, but nothing else.

2. It's not really bullet-proof, but more of a "bullet irritant".

3. Maybe multiple layers of this stuff would stop these rounds, but as far as that goes, if you stack enough of almost anything, it will eventually stop these rounds.

Oh well, a beautiful, if cold, day at the range. We had fun.

Thanks to Pighelmet for the material and to Tman for the photo help.
