I don't reload so I don't do much in the way of inspecting cases very often, so what do you guys think, reload? I've fired thousands of rounds of WWB red label and have never seen a silver primer, but have seen the WWB NATO stuff with silver primers. Thought the edge of the pocket looks pretty beat up also, normal?. This isn't mine by the way, it's from another forum and claimed to be an OOB discharge.

Doesn't look like an overpressure reload to me. The brass looks pretty beat up and mangled but doesn't resemble any of the 1,000's of 9mm reloads I've made. I'd guess the damage happened when the OOB discharge happened.

The edges of the primer are still rounded and show no signs of over pressure. The firing pin strike on the brass looks very odd.

That is a cartridge that has been commercially reloaded at least once. Note the ca. 45 degree chamfer to the primer annulus. Many commercial reloaders use equipment that reams the primer pockets to remove military crimps. They often over-do this and cut far more than is necessary, I have seen many that were chamfered 1/2 the depth of the primer pocket. They simply process all brass the same, even commercial that has no crimp!

I have no basis, but with the variety of mangle marks I'd say it was a reload. A new cartridge might have SOME of those marks, especially after being fired, and fired incorrectly but there's just too many and too much variety of dings. It does look like an 'OOB'. Very likely it is the ammo that mainly contributed to the 'OOB'.

Nice catch there.

Thank you,
I thought it didn't look like a new manufactured case. I collect all my once fired brass and just sampled some of the WWB. I can easily see the crimp that you mentioned on all of it.

The specifications for U.S. military 9mm ammunition require an annular primer crimp and primer sealant. Commercial ammunition does not use those.

Reload? I'd go with probably. (Commercially) reloaded at some time??? Making an "absolute" diagnosis from a photo???

Since the case might have been loaded twice but......
it did not have a +P type marking on it.

I would have to really check out that barrel big time,
for case support and headspace problems.

The first thing I thought of when looking at the second picture was that it was cut to remove a primer crimp. IMO it's undoubtedly cut. It that ammo was supposed to be factory new there is something very wrong.

Are the cases pictured empty/fired or fully loaded ammo? If empty, the primers look very suspect, perhaps fired in an auto or over pressure. And what are they sitting in?

They're both pics of case still in the barrel (pistol) after an OOB discharge. It's on another forum. The guy sent that pistol back to the manufacturer for eval. I don't think they'll beleive that it was factory new ammo either.

Particularly with respect to 9mm and 40S&W, case inspection is critical since several manufacturers (Glock being the most prominent) resolved feeding problems by undercutting their chambers leaving part of the case unsupported during firing. Such "Glocked" cases are subject to catastrophic failure when subsequently reloaded.

The color of the primer is not dispostive as to whether the round is a reload.

The cutting along the edge of the primer pocket indicates it was reamed (and not particularly well, in my opinion) to remove a primer crimp. This case should not have had a primer crimp in the first place, so why it was reamed to remove what was not there suggests someone loading a large volume of cases who is reaming 100% "just to be sure".

The pictures are too small to be conclusive, but it doesn't look like an Out-Of-Battery (OOB) discharge to me. I can't say with 100% certainty, but the failure of a piece of "Glocked" brass on subsequent loading cannot be ruled out.

There was a two part fix for the Glock bulge.

1. Glock changed the feed ramp and the newer Glocks now do not have a problem.

2. The ammunition manufactures made the .40 S&W cases thicker.

Below the feed ramp angle was changed and the bulge problem ended.



The only people that have a Glock bulge problem are people who have older Glocks and do not reload. Meaning they didn't have their barrels replaced by Glock.

I have a Glock Gen3 .40 S&W and have "NO" bulge problem.

Are we all looking at the same pictures? Both pics show a primer that has flowed back and deformed around the firing pin. Overpressure? Withoug doubt. The second shows a case ruptured just above the extractor groove. This doesn't happen with normal pressure loads in a locked breech gun. The primer pocket bevelling reveals it was a reload which introduces a host of possibilities including squib load barrel obstruction, over-charging, incorrect overall length, etc. Round may have been fired in a Glock with the infamous unsupported head problem, but Glocks don't often blow up factory ammo.

Glad it wasn't your ammunition.

Known as "cratered primer", it's a sign of overpressure.

Cratered primer on both.
The 'brass' case (second pic) has the case head indented in the area of the 'uger' of Luger. (Enlarge)
Plus the lettering looks like it was at one time blackened with a Sharpie pen. The blackening done by some reloaders to keep track of certain loads,,the indentation into the head from a configuration in the breech face of a firearm usually only when extreme pressure iinvolved.
It may not have been from this particular gun & firing though, If from a prior loading it certainly wouldn't have done the brass any favors in the strength dept .

Just some observations looking at the pics. Pics can be deceiving though as always.

Could also be leftover from someone sealing the primer with asphaltic varnish (to try and replicate military loading) or fingernail polish (for cosmetic reasons).

True, but I didn't see any of the black marker around the primer, so I figured the reloader/marking the cartridge thing.
The other posts about the deep cut used to remove any existing (or not) primer crimp on the case would have taken that marker away from that area. That may be why there is none around the primer now.

In either instance I'd say it points to the cartridge being a reload which is what the OP originally asked.
