I had a few of these in my range grazing. Almost every single one of them buckled when the expander die got to them. Just to make sure the press and dies were not off, I mixed a few of them in a run of CCI cases on the progressive. Round after round, the CCI was perfect, and every time a nny case hit the expander, it would buckle. According to the headstamp search, the nny headstamp is rvi Partizan-Namenska Proizvodnja, Titovo, Uzice 31000, Yugoslavia. If you wind up with any of these, trash them, they are so thin and weak I am afraid to use them. Buddy of mine said these are sold under the Monarch brand name, but I cannot confirm that.

good to know.

all the brass i pick up seems to work very well in all my dies. if i see any of those i will leave them where they lay. if they are that flimsy i would imagine the rim is probably inferior as well, and that spells stuck case.

thx for the heads up.

I picked up some .380 cases w/that stamp - not good at all, I managed to load them but put them in my 'poor brass' ammo bag for shooting standing, freehand where I don't pick up the brass.

So it appears it may be the same for all nny brass eh? I've got a TON of .40 nny brass. So sad...

Good luck with it in 9MM so far.

Prvi brass works fine for me.

Have maybe a hundred of them here in 45acp. Never had any problem with them. Probably reloaded them about 20 times.
