Took a while to open this one up, we were really unsure what was going on.

That round looks Berdan primed. How old was it? Some older or foreign ammo that is berdan primed can be corrosive and do all kinds of crazy shit if exposed to moisture. I've been told that generally the primer is the corrosive part of such a round. I've seen old berdan primed ammo that had green rings around the primers and when you scraped away that ring it exposed corrosion damage to the actual primer and primer cup. I could imagine such a round blowing the primer out upon firing. I didn't fire any of the rounds I had with that green ring so I don't know this for sure. The ammo in question was 7.62X54R. </div></div>
Standard 7.62X54R is real bad for corroding primers. Especially the surplus stuff.
The slightly more expencive sivler tipped stuff that I run through a PSL seems to last a lot longer.
I throw away any of the rounds that get the green corroding around the primer.
Not to turn this into a 7.62X54R discussion just examples of the corroding:
Silver tipped higher quality ammo on the left and the mil surplus on the right:
You should be able to see the corrsion on the ball surplus primmer on the right. Both rounds were purchased about the same time, with in a month of each other at the most (can not attest to the date of manufacture) and have been kept dry and free from mositure. I only fire the Silver Tipped stuff from the PSL.
