9mm Press Stopper

[lordpaxman]

Nothing stops a press faster than a lock out die or:



It’s the first time I ran into this headstamp in 9mm. Since I was in a wash, rinse, repeat mode this summer, after 10k of cases I’m hard pressed to determine what range this came from. I’m waiting for the next one...

Ouch.

There's something I haven't seen before.

The obvious possibilities for "FNM" are:

• Fábrica Nacional de Municiones, Santa Fe, México (near Mexico City)
• Fábrica Nacional de Munições de Armas Ligeiras, Chelas, Portugal
• Unknown Factory, Mexico

I wonder if that's an officially sanctioned NATO cross or a counterfeit.

I’ve got some WWII vintage Spanish 9mm Largo that is Berdan primed but I don’t think I ever seen any Berdan primed 9x19.

I’m sure it is out there as the OP can attest.

I’m sure it gets your attention quickly at the decapping station.

Yep, berdan primed cases will do that. Speaking of your lock out die though, you might be able to set it up so it catches stepped 9mm cases. My Dillon will.



It won’t help with the Berdan cases but can catch others you can’t find without looking inside them all before you start.

First decap pin I ever broke was on some Berdan Indian 7.62mm ammos I bought for the M1a. That's why they call it 'snake eyes...'

Maybe Portuguese:

Well there’s something you don't see too often. I run into about 3-5 a year and they suck. I hate those more then small primer 45.

 

[Dudedog]

Those tend to be a bit hard on decap pins

Interestingly, I found over a dozen Berdan primed 9x19 cases in the last 2000K of range brass I bought ... along with a handful of .380 cases. Fortunately, I didn't break the decap pin on the first one, and after that I eyeballed the inside of every case case.

Portuguese Via the Congo. A bunch of 7.62 NATO came in with the same headstamp and date range in the mid-80's. The 7.62 had a lot of dead primers and some corroded cases due to poor storage in the tropics.
