Any information will be appreciated.
I have a thread about how to determine if an AR barrel is .223 or 5.56 that got kicked to the gunsmithing basement for some reason, I see lots of threads live a long life on the main message board that are far more gunsmith related, so lets see what happens with this one.
I fired this ammo in the barrel mentioned above, out of 30 rounds one blew out a primer, two leaked around the primer, and a couple had printed in the ejector, most looked ok.

The case on the left seems normal, second from left printing from ejector, third from left leaking around primer, and fourth from left blown primer and heavy impression from ejector, I am assuming all pressure related.

This is the ammo, you may not see it but the case on the left has a questionable crimp and what the heck is going on with the one on the right? Yes, that is a hole or void in the primer.
This is gun show ammo I bought years ago, I did some reading that others had similar problems with pressure, has anyone here had issues with this ammo or know any thing about it?
I have pretty well sidelined this ammo, I put it in a box marked "use only in actual zombie apocalypse".
