Strange Ammo Malfunction

[Doc_Glock]

I'd half expect this from Freedom reman... but not PPU.

No kidding. It is actually beautiful Ammo externally. It looks primo.

[Doc_Glock]

Do they fit the chamber of your barrel like they do the case gage? That bullet looks really long. Do they spin freely when chambered? Pull the barrel out to chamber check.

Will be a day or so before I can do this but
thanks for the idea.

[Doc_Glock]

Any pull downs of loaded rounds? I doubt it's anything internal or left over from manufacturing but who knows.

Do the cases with large extractor cuts have noticeable case volume or internal depth differences?

Maybe chrono the stuff if you still feel safe shooting it.

All the above is beyond my capabilities.

If it helps, these are the pistols that have issues with the ammo:

Difficulty chambering:
P30l
Steyr MA1
PPQ

The HK seems worst, but still malfunctions are only a 1-2% thing. Debris flying is multiple shots every mag.

Failures to extract:
Beretta PX4C

Pistols that don’t seem to care:
Glocks
Beretta 92s

I have not tried it in anything else.

Shoot it through the Glocks and Beretta’s, and shoot something else through the others.

There is a noticeable rim inside some cases. It is a dark ring that seems a little gooey. I don’t think any brass is missing there but it is the right shape.

That's likely bullet sealant if they are made to true NATO spec. Like mentioned I'd cease and desist firing any of more them until you hear from the manufacturer. And I was just thinking about nabbing a case of this myself.

I've seen 9mm cases of European manufacture with and interior step. I assume it's to help prevent bullet set back. I've seen malfunctions occur when the case separates at the step, leaving the front section of the case in the chamber. I wonder if something similar is happening here? The case exteriors don't seem affected.

@Enel, are you sure that's brass and not jacket material? It looks like what you get when a revolver is shaving bullets, but I've never seen that in an auto.

I heard back from PPU promptly. Here is the text of email:

“the nato 9mm is meant for military style carbines and in most cases too hot for pistol use. We recommend standard 9mm ammo for pistols. We can trade you the nato ammo for standard 9mm.”

I don’t think I will bother trading it and just shoot it in the 92s and Glocks.

I had heard HKs like relatively hot Ammo for the first few thousand rounds which is why I bought this originally.

It does seem to cause problems with failure to extract in the PX4, which may be to higher pressure?

And maybe this is a great excuse to buy a 9mm carbine

I don’t know. The material is really thin and much smaller than it appears in the photo above.

Are the bullets jacketed or plated? I have seen plated bullets do funny things because they come apart sometimes.
