The reason the penetrators for APFSDS-type ammunition are made
of DU or tundsten carbide is that, at the velocities they reach,
a steel penetrator would shatter when it hit the target.
This is usually not a problem with small-arms ammo. So why 
bother with the added expense of exotic materials when steel
serves quite well?
