Eh, yes, but I meant tumbles in the air - a kind of unstable bullet. I vaguely remember some talk about a French bullet (9mm, I think) that was supposed to tumble in mid-air and thus give the bullet the mentioned dum-dum effect. Green Berets? At 25 yards? That's about 25 meters, right?! Hmm, well, that sounds odd, unless of course they didn't shoot to kill in the first place. With all due respect, I really don't think that anybody with 7 shots to the main area (the body) would run very far. But ok, as you say, it was a rather extreme case, and a lot of adrenalin will do wonders... Well, it's all a bit academic, theory contra real life, I'd say, but very interesting and informative nonetheless. Best regards! - Bluenote.
