http://en.wikipedia.org/wiki/Dum_dum
Dum-dum is the colloquial name for several types of modified exploding (more 
properly known as expanding) ammunition for firearms. A normal (jacketed) 
round that has had notches cut across the top is one example. The effect is 
that the bullet deforms upon impact into chunks, along the cross 
indentation. This creates a larger wound channel, with multiple exit points, 
and greater blood loss and trauma. However, altering a bullet in this manner 
makes it less aerodynamic, and hence less accurate at longer ranges. Another 
way to make the bullet expand, rather explode upon impact with the target is 
to make the bullet with an enclosed cavity filled with mercury or glycerine 
(this type of bullet is mentioned in Frederick Forsyth's book The Day of the 
Jackal). When the bullet collides with an obstacle it rapidly slows down 
while the liquid inside of it retains its inertia and has no other way to 
release its excess energy that to rip through the front of the bullet, 
creating a jagged bullet slug and some lead fragments that continue to rip 
through the living tissue, creating enormous hydrostatic shock and a 
large-size wound. A hollow point bullet is sometimes referred to as a 
"dum-dum".
