wellyou can have DRT or you can track them it all depends on shot placement and what ya hit them with. hit them on the scapula,(the shoulder blade) with a high velocity thin skinned cup/core bullet, this is the place of most resistance, so you get more violent expansion, which does wonderful things
first a massive shockwave travels throughout the body, pushing blood backwards through the major blood vessels, and travels up the CNS to the brainstem, causing all systems to shut down NOW!, then the completely expanded bullet is sending fragments into the chest cavity shredding the heart and lungs. and ya lost 1 whole shoulder and probably the other.
