You can bid on this stuff just like you did the dehumidifiers, but watch for the Statements like Kris Kringle wrote. Call your yard and ask if they will submit a Certificate of Destruction and call the contact at the GOV Liquidation site and ask if they'll accept the Certificate. The yard will fax it directly to the contact when they receive the shell casings, etc. Plan on going directly to the yard from the pickup site with no side trip to your residence, but you might clarify this point with the GL contact. Also, read the GL directive BEFORE bidding. I seem to remember something about a background check and checking identity when you go to pickup (it's been a couple years, so I forget the details). I watched several sales of ammo brass and decided the profit margin was nonexistent or too slim. If I remember, you didn't need a Certificate of Destruction for anything less than .50 Cal.
