How is it that a bullet that is 12.7 mm in diameter can kill somebody with so much more bodily damage than a 20mm rebar rod that is impaled through the body? I see stories of people surviving impalement all the time, but a shot with a .50 cal to the same area almost always results in instant death. Shouldnt the bullet just go through its target because it travels so fast?

The rebar isn’t moving at 2,910 feet per second, for starters. Nor is it spinning at a rate of one turn every 38 inches (that’s roughly 55,000 rpm). It isn’t the size of the hole, it’s the amount of kinetic energy imparted which results in severe hydrostatic shock.
Edit: added the rpm for the rotation.
