Doesn't sound too awful bad for that much brass. It can come from much more expensive places.....like new ammo.Definitely not berdan. I managed to decap some of it with my old decapping pin before it gave up. It's "Igman" brand stuff that my son bought a couple of boxes of from Rural King. It's crimped and sealed (assuming lacquer).
Just not worth the effort and decapping pins for 25-ish cases. Once fired 223/5.56 that's been decapped, cleaned and trimmed is cheap. Son bought 1000 once fired cases a few weeks ago. Was supposed to be all Hornady, but they sent 500 Lake City and 500 Hornady, all decapped, tumbled and trimmed for $99.
I'm converting 250 of the Hornady to 300 Blackout (got 100 done so far). Figured if I could decap the Igman, I'd just make 300 out of it, but meh.
