This is one lucky guy..His 50 blew up in his face.
They may also be rounds purposely loaded with PETN, RDX, or some other KABOOM! ingredient and planted in a combat zone for the enemy to scavenge and attempt to use. I do know this has been done with mortar rounds and 7.62x39mm.Real simple,don't shoot exotic collector rounds(75$each)...esp military----you have really no idea where these rounds have been sitting around for 20+yrs...These are'nt rounds that have been in a basement or someones closet....they've been all over the world in various storage conditions...which is why they warn you not to shoot them.
I agree, he wants to be Hollywood. You can survive a cut to the external or anterior jugular as they are smaller veins , totally different if the internal jugular is involved especially the right side as it is the larger vein. Depending on the injury exsanguination can occur within 5 minutes if pressure is not applied. The internal you could bleed out in a minute.I'm thinking that this is a bit over dramatized.
