Default primer issues on 9mm

I started reloading 9mm today on my Dillon 650. I a large batch of assorted brass. I had about 20 today not take a primer, or if it did it totally destroyed the primer. I reload 5.56 also and swage those, do they put crimps in some 9mm?? If so, will a 5.56 swage tool work on 9mm? Being they are both small primers?

Thank you

Jay

I talked to someone at LEE because I was having a primer issue with 9mm as well. I was told most modern 9mm is crimped. I haven't really loaded 9mm much recently so I haven't been looking at the cases I have but that could be the issue.

Some some are crimped. The ones I've noticed are WCC.

Yes, the same tool used for your 5.56 will swage your 9mm.

When you see the NATO mark on a 9mm shell then yes. Crimped. I am unfamiliar with your swager. I do not know what you used, but any SR or SP primer pocket swager should work for any SP or SR primer pockets.

Worse case, check your cases with a primer pocket cleaner tool or just hit them all with a touch of the reamer that sits on a driver or drill... (the latter is not the best idea, but it works).

Hmmm. I wonder if that was my problem with the loadmaster. And here all that time I just thought it was a jacked up priming system...

Maybe the majority of modern 9mm thats manufactured today is crimped (Military orders for NATO countries) but the majority you'll find in stores and at the range is not.

I don't really know if what I was told is true or not but that's just what I was told. I have yet to confirm or disprove that.

I was just saying that it's possible that they're crimped since it seems that there are crimped 9mm cases out there (again, according to what I was told).

I'd say the majority of store brands are uncrimped but if you get a military manufactured box...then it will be.

For example, S&B is typically uncrimped but if you get one made for a military, it will be.

Honestly...just toss the crimped ones....not worth the trouble..

That's 99.99% likely the issue.

Even S&B uncrimped brass has pretty tight primer pockets that could benefit from swaging. I just throw all my Crimped, Nickel and S&B brass into a bin to load when i know I'm going to loose my brass (training etc.).

~5% of 9mm pickup range brass is crimped, that is enough to futz-up Dillion 650 ops.

It is in the initial inspection:
Berdan...spits & bulges...just plain old fubar pick-up brass in any caliber.

Ok thank you for the replies, and info. I think I will sort through my bin and see how many I find. It may be worth it to just get rid of them. If there a lot I may save them for the future when I am low on brass and have the time to swage them all.

Thank you

Jay

Back in the old days, I would chamfer every case lightly inside and out and, if the primer pocket was crimped, run the chamfer over the primer pocket to remove the crimp.
This eliminated brass shavings from the sizer and expander and allows one to seat jacketed bullets without having to flare the case mouth.
Just the way we did things in the Jurassic Era.

recently picked up a dillon 650 and loading 9mm. i haven't had any problems with priming any cases only about 150 though. the problem i did run into is it didn't seat the primer deep enough. ended up having to adjust the priming pin. not sure if that would help seating it. but double check primer depth is in spec too though.

Thank you I will check that. I did have some do that, I thought it was from a crimp. I did not know you could adjust the priming pin, I am going to have to read up on that.

Thanks

The dillon super swage 600 has the parts where you can swage 9mm brass. Like most others said NATO marked brass (usually WCC) will have a crimped primer pocket.

Ok I think I have a lot of 9mm that is crimped. So I think I may go get a universal decapping die, and hook up my swage upgrade where the primer seater goes and spend a day swage all my 9mm brass. Now that I think of it, reloading just got more important, with the new ammo purchasing rules next year. So to able to use all I have, I think this may be the best solution. Running it through the machine, should be faster than doing it all on a separate tool or by hand. I did swage 5.56 by hand years ago before my Dillon. But now with the tools I have, "work smarter, not harder"

Thank you

Jay
