On your Yugo ammunition, is the primer flat or dome-shaped? IIRC, when Igman used their export headstamp "IK" instead of the domestic, Cyrillic "NK" and a flat, nickel plated primer, the primers were non-corrosive.
As for the "Egyptian" stuff, can you post a picture of the head stamp and box? Typically, Egyptian ammunition has an Arabic head stamp. There was one lot of surplus that came in some years ago with a non-typical "generic" head stamp like what you describe, that had a different primer compound, either non-mercuric or non-corrosive and the box was marked as having a shelf life of 10 years or something to that effect. IIRC the head stamp was dated 1994. *Edited to add "nickel plated" to the Yugo description. |

IMO, Yugo M67 is some of the best x39 ammo out there. It has corrosive primers.

Yes it is, but its my favorite surplus commie 30 ammo. I stacked it deep when it was cheap
 After shooting the stuff I scrub everything down in the basement slop sink with hot water & dawn, dry & clp everything, never had a problem in the 2 decades of shooting it. |

Is the PPU M67 stuff corrosive? I've seen it on websites where it doesn't mention it one way or another and on a few it states "non-corrosive".
Ammo in question.  |

When I put the sku number ( SKU: PP76239B ) in a search any website selling it that actually mentions it says it's non-corrosive and the rest just don't mention it either way. I've yet to read any place selling it that says it is corrosive. I'd rather avoid pouring boiling water through a firearm and then blast it with oil before cleaning just to make sure water isn't being trapped and causing rust. I've had my fill of that with all of the surplus ammo I bought over the last few decades so I'd rather avoid it with this stuff if possible. |

All PPU I’ve seen is new commercial production with non-corrosive primers.
If the writing on the box is in English, it’s not surplus. FWIW, PPU website lists their new production m67 7.62x39 as ‘non-corrosive’. |

Based on the commercial headstamp, box markings, and the flat primer profile, I would be fairly confident this particular ammunition is non-corrosive. |

If you use boiling water the metal will get hot enough to dry itself, so it’s not really a big deal to do it. |

yes.
M67 is IMO the best 7.62 round made. Excellent ammo. Pour water over everything and clean as normal, that's it. ETA: I prefer 1/2 ballistol and 1/2 water in an old windex bottle. Does the same but leaves a little coating to protect metal till properly cleaned. (7n6 shooter here) |

"IK" headstamp is Ingman made in Yugoslavia. It was imported back in the 80's (maybe the 90's too for a short while before the war) under Hansen brand I believe. I shot a bunch of the Yugo stuff with "IK-85" headstamps. I still have some and it's commercial non-corrosive. Good ammo.

PPU commercial ammo is boxer and non-corrosive. The white box is just the current packaging they use for military contracts, the brown box surplus yugo used the same size boxes. Some vendors say the white box ammo is berdan primed, others say boxer. I bough some years ago in white boxes and clear battlepacks that was claimed to be non-corrosive and it was repacked surplus ammo with 70's headstamps. |

I think that "M67" is used the way we use M193 or M855 here in the US. The authentic mil-surp Yugo M67 ammo that comes in crates and plain brown boxes on the 10 round round stripper clips has corrosive primers. Meanwhile, Yugo and former Yugo manufacturers may still label their FMJ Ball ammo as "M67" even though it is commercial, non-corrosive ammo. If it has 80's or newer dates on the headstamp it is non-corrosive. I was just shooting my "M67" ammo with IK-85 headstamps with zero concern that it was corrosive. If you have a lot of questionable ammo and really gotta know for sure, you could pull a bullet, dump the powder and "pop" the primered case over a piece of steel and see if it starts to rust in the area. If it's corrosive it will start to rust only in the area that got blackened from the primer detonation. |
