9x19 vs 9mm

I started going through my clean deprimed 9mm brass to separate any crimped pieces before loading. I found a small percentage of them head stamped 9x19. I’ve always thought of these the same as 9mm in dimensions. I used a Ballistic Tools swage gage and found the 9x19 primer pockets seemed smaller and resisted fitting in the gage. So I seated a few primers in these 9x19 cases with my RCBS hand primer with no difficulty. I don’t know which brand of primers they were since I use a variety of brands.

It’s a good thing I examined these cases because I found one with a couple of ss pins jammed in the pocket and one with the spent primer still partially stuck in the case. I always look at a spent case before placing it in the machine.

So far I haven’t yet come across a crimped case.

Anyone have difficulties with 9x19 cases?

Do any of you swage your 9mm cases before loading?

Thanks,
Steve

I toss nato stamped cases, usually crimped, just not worth the effort imo. I also toss most foreign brass as dims seem all over the place. So I stick to US manuf brass & pmc also seems to work fine. I load mostly 147gr for practice & competition, so thicker brass can be an issue, bulging the cases down toward the head.

That is basically what I did, except I drilled a hole near the top of the thumb lever and installed a cotter key. Then from HF spring kit attached it to the HF cotter key back to a L screw hook. Instead of grabbing the thumb lever, just place the case on the shaft and press down on the case and shaft. Swag and automatic eject.

I still use pretty much any kind of 9mm I pick up from the ground. It's just not worth the time and effort to sort.

I may get to the point where I start buying new brass for majors, or something along those lines. But I think I would probably still use unsorted range brass for practice and club matches.

My rejection rate from the case gauge for practice ammo is typically under 1%. Bullets get pulled from those rounds every few months, and everything else gets thrown out.

So basically I sort brass in the case gauge.

Don't use IMT, AmmoLoad, Freedom Munitions or MaxxTech. They are stepped, which results in a substantial reduction in case volume, which could lead to serious pressure using books loads. Plus if you try to run a 147 gr in them, it will jam the shieette out of your press. And the little fkckers can separate upon firing, leaving a brass sleeve in the chamber and a dead gun. They are complete junk.

I've lately been in the 9mm brass sorting camp. Loading cast for a couple old 9mms, the groove diameters like .358" bullet diameter, but the chambers don't appreciate the extra volume. So that ammo gets Federal cases since it is thinner. Win are close, and those get mixed in too. Any thicker and they don't want to kerplunk consistently.

On the other hand, I made a dumb purchase of some pulled fmjs. Sized .354". Those need thick-walled cases to get enough neck tension. So R-P, Magtech etc. are the ticket.

For a while I was swaging primer pocket crimps. I changed my ways after considering that I have probably a lifetime supply of non-crimped brass on hand.

For everyone who is picky about their brass, feel free to just mail it to me. I'm not proud and I'll reload anything.

Do you have a lot of experience reloading and shooting the types 9x45 mentioned? All it took for me was one case separation at the step with a FM or Ammoload case.
