The high-velocity bullet causes a huge swath of tissue damage that extends several inches from its path. It does not have to actually hit an artery to damage it and cause catastrophic bleeding.

The bullet has to go somewhere, so the cratered steel sends it in the path of least resistance. Good, well-made, and smooth-faced steel targets actually use ricochet to their advantage by safely ...

This post will discuss the comparative velocity and kinetic energy of AR bullets and how those factors affect bullet penetration and wound severity.

The AR-15 fires bullets at such a high velocity — often in a barrage of 30 or even 100 in rapid succession — that it can eviscerate multiple people in seconds.
