We had some. Turkish I believe. It was ok. Had a few bad ones in a couple hundred rounds. And some bad bullet seating in case on some. But that was 3 years ago or so
I've run plenty of ZSR 9mm and it works I guess. about one in 25 had bad primers. I would absolutely avoid their .308 though. Nabbed a few boxes to run through my R700 and experienced several split/bulged cases that had to get hammered out with a dowel rod. Can't imsgine the issues it would cause in a semi automatic platform.
