Interesting 9mm ammo malfunction
So I had a problem this weekend that I have never even heard of before.

I bought a Beretta 92s and took it to the range for the first time Saturday. It was used, looked to be in good shape, but I was prepared to have some issues. (The mag springs felt soft, ext.)

Load a magazine with 124 grain PPU NATO.

Fire 7 rounds, and have a FTF on the 8th round.

Ok. Must be a mag issue I think to myself. Drop the mag, clear, insert new mag and... FTF.

Repeat this a few more times, then attempt to load a round by hand, and none of them will chamber.

Take the gun apart, and rounds will not even seat in the barrel.

I go home and start looking everything over. Chamber a snap cap no problem... ok must be the length of the 124 grain bullet...

The chamber looks like it has a buildup of copper at the throat of the rifling. Ah, there's my problem. The barrel looks new, but maybe not?

So I start cleaning the barrel, and notice it is extremely tight at the throat of the rifling. After fiddling with it for a long time and looking it over with a bore light I realize that a jacket has ripped off a projectile and has gotten stick between the chamber and rifling.

I go to Ace Hardware Sunday and buy a wooden dowel, and I was able to beat the jacket out with a hammer.

Took the gun back to the range and put about 120 rounds through it with no problem.

Seems to be a failure of the ammo.

I have sent Privi Partizan an email and am awaiting a response.

Here is a picture of the jacket on the dowel rod.

Cant see pic and can't see on link because I don't have a user account.

I attached. The rest of the thread is from the community saying they've never seen a head separated case stuck in the barrel like that before. He said it's the jacket of the bullet but that doesn't seem right.

On a side note, it looks like Photobucket has decided to give our photos back. It's nice to see the old range photos I abandoned. Imgur seems to be working great so far, so will stick with that.

It's the jacket of the bullet head.

I’ve experienced similar issues with poorly plated heads. I prefer jacketed heads for just this reason.

so the lead core squirted out and left the jacket behind?

did the box of ammo say "sabot" on it??

What's the KHSC policy on using depleted uranium?
