do you enjoy the mushroom effect of the projectile tearing thru the flesh?
Why a Hollow Point
In the self defense context, an expanding bullet is good for a variety of reasons.
Generally speaking, to stop a violent attacker with a handgun, the bullets need to either disable the central nervous system (brain, spine) or cause massive blood loss which fuels the brain and muscles.
So called “head shots” are difficult targets, so most instructors train students to aim at the “center of mass”: the upper torso region housing the heart and lungs.
Without trying to sound crude, the bigger the holes you make in an attacker, the quicker he will bleed out
