If you wanted the target to be "shot" that would be sub-optimal as it would leave a hole the size of the bullet rather than a line the width of the bullet. Maybe for something behind heavy armor or earthworks you'd want an exploding projectile.

Or maybe you're treating cancer and you want to shoot only some tumors.
