"Blended metal" bullets; much heat after impact? Can anyone tell me? These bullets supposedly will penetrate body armor, but not drywall, and are alleged to pretty well explode when going through flesh. I've read a report by a contractor who used one in Iraq and said the soft tissue damage caused by it was massive. Now, my question is this; would this bullet release a lot of heat after impact, if the claims that it explodes in the body are true? I have a good reason for asking this, and if I get a good verifiable answer, the person who provides it may become at least semi-famous, depending on a few external factors not under my control - but it's POSSIBLE. Oh, I know you physics types don't crave fame, but a little recognition for a good cause couldn't hurt, could it?
