Need Help With 9mm Headstamp

[oldfoneguy]

Well that's good enough for me thank you gentleman.

I don't use comblock ammo in anything I own. I'll pull the heads, get a confirmation weight on them and toss the rest. Reason being, I'm in the process of loading up some carbine rounds with bulk brass most likely range pickups. ALL the Chinese brass is in failure after a single firing. I don't expect any great things from this brass either so no reason to play with it waiting for a case failure.
