TG> DS> Actualy, the 20mm DU round has a thick jacket to protect the barrel.
TG> DS> I beleive the jacket is aluminum.  Their made using *spent uranium 
fuel
TG>Hmm, Aluminum flashes at high velocity, IE: friction (Thermite).
Thermite is Aluminum?  I don't think so.  The Aluminum may get hot and
melt just from the conversion of energy, but I don't think that it would
*FLASH* like an incenderary round.  An incenderary round has a magnesium
alloy type of core and will flash/burn on impact, very much like that
of a depleted uranium round (but without as much destructive force and
no radiation).  What you maybe thinking of is a White Phosphours (WP)
round.  That is a WP core with an aluminum jacket.  When the projectile
impacts an object, the jacket either breaks up or peels open exposing
the WP which will begin burning as soon as it's exposed to the air.
Ground crews don't like to mess with those too much because the jacket
is preaty thin and has been know to go off when loading it into the drum
magizines of aircraft (ie., 20mm, 25mm, 30mm).
