(Very, very graphic death) https://x.com/_geopolitic_/status/1965851790714482943 (not safe for life / NSFL)
[Graphic description] What kind of gun could that have been? Incredible amount of kinetic energy—you can actually see a hydraulic pressure wave oscillating through his entire chest. This was obviously fatal, if anyone wasn't sure. Probably died instantly, given the neurological "fencing" response (suggests spinal cord was hit—never mind the artery, he was already dead).
Also: smaller assault rounds like 5.56 can in fact do more damage than larger ones in some case because of its tendency to bounce around in the body.
