I think in the next couple months or so I'm going to start loading 9mm, just need to get some projectiles. I've read where a lot of people chunk the NATO brass due to having crimped primer pockets, but I had a decent amount of this ammo and now a good bit of brass from it. Recently I pulled one of these cases out of my stash and tried to gently prime it to determine if I'll need to ream the pockets. Well it primed fine with no real extra effort to my surprise. So is this typical of this brass or is it just a crap shoot whether they'll need reaming?

The ones of you that have loaded this brass recently, what have you found to be the case?
 
Some of it is crimped and some isn't.

That's the best I can tell you from loading 10k+ 9mm so far this year.

Thanks for your insight.

The brass I tried was from the usual white with black lettering Winchester NATO boxes, but I have a case I haven't cracked into yet that's in a plain military style brown box that came packed in a 50 cal can. I assume it's the same exact ammo, but am wondering if the crimps will show up on these or not.
 
What is your method of testing for crimp or no crimp? I have a small tool for pocket insertion.
 
I can usually mash primers past the crimp in 9mm brass with my LCT. I only do it unintentionally if I miss one during the sort. But they usually go in.

That's been my experience too, on my LCT. I got so used to using a strong hand while seating S&B spp I don't really think about it.

Like others have mentioned, I've seen the Winchester NATO cases with and without crimp when I pick them up at the range.

And there's a lot of reloaders that won't buy anything but new brass. Removing primer pocket crimp is very easy and you don't need a dedicated "reloading tool". When I first encountered primer crimps I immediately thought of a countersink to remove a few thousandths and give the primer pocket a slight taper (life long machinist/mechanic). When I de-crimp a lot of cases I'll use a power screwdriver or hand drill holding a 1/2"x60 degree countersink. Quick, easy and inexpensive. I've done thousands in 9mm, 45 ACP, 7.62x51 and 30-06. Some may be able to force a primer passed the crimp, but that don't fly for me.If you find this task a PIA, then toss the military brass, but for me at least, it is a one time process that gives me some extra bench time (I like reloading)...

I bought an RCBS primer pocket swager kit to use with some rifle brass. With mixed brass, I put the swager head in the press and place a piece of brass on it. If it slips on easily, no crimp and I move on to the next one. If it doesn't slip on, I operate the ram to remove the crimp. It takes a while, but you only have to do it once.
 
RCBS Military crimp cutter works great. I used one last week and it didn't take away too much material and prime pockets were still tight.
 
I found a lot of primer pocket depth variation with 9mm NATO brass. The crimp wasn't problem as my 1050 easily swaged them all. Despite that, primer depth was inconsistent in this type of brass. Considering the wide availability of free high quality range brass, I don't think that military 9mm brass is worth the trouble.

I de-prime before tumbling and can feel a crimped primer by the extra pressure needed to dislodge it.
If I feel it, I just turn that case over and chamfer the pocket to remove the crimp with a case deburring tool...done.
Just de-prime with a universal de-priming die, NOT a resizing die as it will mask the variation in the effort of de-priming.
works for me,
:D
Edit: You can use a larger caliber sizing/depriming die, 45acp or 44m, instead of buying a Universal die.

After swaging six hundred cases with the RCBS Swage Die II, I find it much easier to find a good deal on non-crimped brass...
I also have an RCBS Swage Die II for sale.:)

I have seven or eight gallons of range brass to use as plinkering fodder. I'll use my very large one and a quarter inch drill bit for those! I like the one hundred eighteen degree cut, as opposed to the chamfer tool's angle.

Check out a CH4D swager. Much better than the Recycled Crummy Broken Stuff model.

I sort the crimped brass on the press. It goes in a bucket. I don't place a lot of value on my time but I can't bring myself to remove the crimp from 9mm cases when I can get them for around $0.02 each, or free at the range. I picked up over 1000 extra 9mm cases yesterday.

Yep, too much free good brass to worry with crimped 9MM.

I don't have a lot of 9mm squirreled away yet, with the pro brass hogs where I shoot becoming aggressive, and I have had to chase them off recently while shooting 9mm.
They walk down the firing line and are equipped with floor installer type knee pads, extended grabbers, buckets, etc.
Because of this, I have joined a club with a private range and hope to build up a stash of brass, like everyone else.
:D

If I'm shooting ya better not be picking up my brass.

Thankfully I belong to a private club where this is not a problem.

yeh, an ND into the dirt would get there attention!
I think there's a thread somewhere about non-shooting brass hogs...
One guy dumps out all the trash cans and goes thru everything, but he puts the stuff back into the cans though.
The range is owned/run by the county and they shut down the range one morning a week so the inmates can clean-up the crap people bring out there to shoot at, then leave it there :cuss:
:confused:
