The saftey slug is a copper cup filled with lead shot that is capped with
a fragmental plug. When the slug hits the target the cap fragments and
the cup splits open dumping the shot and all of the slugs energy into
the target.

The hydroshock slugs, the ones I have seen, are hollowpoints with a
post in the center. When the slug hits a soft/wet target. The hyraulic
pressures generated as the material flows over the post cause the
hollow points to expand. This expansion is supposed to be more reliable
at slower speeds than normal hollow point.
