Grendel as a Universal Infantry Cartridge

[LRRPF52]

Not only break apart, but the lead core blows apart into a shower of dust. I think the term "lead shower" comes from the x-rays of 5.56 injuries that have been documented.

I prefer actual x-ray photos, not artist drawings, although the drawings you referenced basically represent what happens:





The tissue on guys I've seen who were shot with 5.56 looked like someone took an M80, buried it under their muscles surgically, then detonated it. Explosive hamburger...

The one who survived that was shot in the arm had basically Titanium rods and screws to replace the ulna and radius, which were fragmented so badly that only the heads, styloid processes, and olecranon were left...the main shafts of the bones had been fragmented into a bunch of small crumbs, like Captain Crunch cereal.
