Had two relatives worked as civilian employees at Hawthorne and Sierra Army Depot at Herlong for their whole career. Trying to keep this post short...I would be very surprised if there was any increased value in your ammo. If your Pabst Blue Ribbon comes out of the store in a Kroger bag or a Piggly Wiggly bag...it's still Pabst. At Sierra Army Depot, for years they burned old inventory corrosive ammo in huge pits and covered them over. I seriously doubt any was released through CMP. At Hawthorne they released a lot of AP through the Property Disposal Office, which I purchased for Hi Power practice. Never saw a dated headstamp that could have been corrosive.
