Thanks SG500. Any thoughts on potential DU presence at the site?

Hi i'm sure there are EOD guys on BOCN who are much better qualified than me to comment on DU contamination.
All I can really say is that the rounds I have aren't the DU versions, they are some sort of Tungsten alloy. The DU projectiles are a much darker colour. If you look at the fired one in the link below its a DU one, the article give some info about DU contamination also.

There is quite a bit of info about DU contamination from Davey Crockett spotter rounds on the internet. Google "Davey Crockett" and go down the list.
