Please elaborate on "molten metal" from hitting the plates????????
Wish I had a photo of them, it took me a while to figure out what they were. Most of the gray streaks were 1/16 to 1/8" wide, and a few inches long. If you've seen any of those high-speed photos of bullets splattering on steel, I believe it was the lead core of the bullets melting under the impact, and being turned into small molten droplets. The paper target was a foot or two behind the steel plates, and 3-4 feet to the side.
If you watch this video, at 2:00 you will see a few cases where lead clearly looks like it is turning to liquid after a strike.
