charred wood? I have seen black staining around steel jacketed bullets that looks like charred wood, if they have been in the tree for several years. But fresh bullet holes even from 22-250 bullets at 4000 fps are clean without charring. I thought meteorites were cold on impact? can anyone explain charring from a 70 gram object that impacted at less than 300 fps? at 200 fps it would have bounced off the tree and at 350fps torn it in half.

   Its still a very cool looking example of a meteorite.
Cheers
Steve
