I got these out the other day and found this corrosion on these 22-250 Hornady VX rounds. I started to clean the crud off when I noticed the cracks in the neck; you can see a thin green line that starts in the large green area and runs from the shoulder down the neck on the 2nd case (L-R). I have a few with crud around the bullet and case but the bulk is where you see it.
I know it is a faint line but there is a crack on every case where you see the crud. The first round is also Hornady the 4th is a Remington, stored in the same place but without the corrosion.
Can anyone explain this? Is the Moly coating causing this problem?
Some of the VX rounds show signs of having been chambered but not all of them. The second photo above of 20rds is right out of the box.
All of the ammo below was stored in the same location, this not in a basement and there are no dampness issues. All of the ammo is good except the VX, the Moly coating is the only thing that separates them other than manufacture.
