Interesting .40 S&W casing I found.

Zephri · 04-07-2008, 10:50 PM

Check out this odd .40 S&W I found while putting up my targets at the range.

I'm guessing one of 2 things

1. severely over pressured round.
2. some one shot it in something not chambered for it.

Judging from the deformation I'm guessing the latter.

STITCH · 04-07-2008, 10:52 PM

Holy Cow!!! That is crazy!!! I am glad I didnt shoot that one!! Looks to me that someone shot it within a different cal then it was suppose to be!! Dang that is crazy!

GlockMeister · 04-07-2008, 10:59 PM

Looks like Wolf brand ammo cases also? lol

Zephri · 04-07-2008, 11:08 PM

it's CCI brand with an aluminium case.

and I'm pretty sure it was fired out of the wrong gun, because of the bulge near the bottom of the case.

GlockMeister · 04-07-2008, 11:21 PM

Oh ok, still looks like some of the Wolf cases though. lol

But where did all the extra metal/aluminum come from? It isn't like it was folded into it and then upon the bullet leaving it came out. And it does look to have a neck? I think it just might have been a different caliber because of the neck; And the neck looks just a tad taller then the top of the .40 round. Just an observation.

TXplt · 04-08-2008, 12:10 AM

I wonder if it was a .357 SIG fired in a .40 SW ?

Mooseman684 · 04-08-2008, 12:43 AM

That is Not a .40 Cal casing on the right, Unless it was a Blank...
That casing cannot "Grow" that much...

GlockMeister · 04-08-2008, 12:52 AM

That's what I thought Moose. And then look where the one on the right is necked. Had to be maybe a what 7.62X25 maybe? Look at this image I found? Obviously the one on the left looks like the one on the right and visa versa? To me anyhow. Not that it is, but looks close anyhow...

AKHunter · 04-08-2008, 12:56 AM

Does the casehead stamp say .40SW on it ?

Mooseman684 · 04-08-2008, 01:03 AM

CCI does make a .40 cal shotshell.....It looks longer than a normal casing !

GlockMeister · 04-08-2008, 01:17 AM

It is longer, look at the neck. It looks like a 7.62X25 dag nabbit. lol

just_a_car · 04-08-2008, 01:30 AM

Looks to me like someone was dumb enough to use a 10mm round in a .40S&W barrel. That would also explain the over-pressure cracks.
You can see in this picture that the .357Sig (third from left) is the same length as the .40S&W (fifth from left), but the 10mm (fourth from left) is essentially a .40S&W Magnum, and the case length matches that you're showing in the first picture (The 7.62x25 is second from the left):

The original and the key for which is which is here: Image:9mm 7,62mm 357sig 10mm 45SW 45GAP 50AE 002.jpg - Wikipedia, the free encyclopedia

Zephri · 04-08-2008, 01:54 AM

This picture should solve this problem. Their both stamped the same.

just_a_car · 04-08-2008, 02:11 AM

Maybe just an over-pressure round and the soft aluminum "squished" around the bullet before finally letting the bullet go?

The one on the right in that pic is definitely striker-fired, as it has the "sweep" I see on my GLOCKs (likely a GLOCK-fired round). The one on the left looks like it had a round firing pin, but it's hard to tell, since it does have what looks to be a bit of a sweep.

So, which of the two is the "ugly" round? I'm guessing the one on the right, as it seems the primer is pushed back a bit more, as one would see with over-pressure.

Zephri · 04-08-2008, 02:16 AM

It's the one on the left.

Now, that's just weird. That primer doesn't show much in the way of over-pressure. I'd expect at least a little cratering... maybe I just can't see it from this angle.

Personally, I never intended, nor will I ever use aluminum-cased ammo, but this oddity kind of adds to the circumstantial evidence that I shouldn't.

GlockMeister · 04-08-2008, 09:43 AM

WOW, they are both indeed .40 cal. Go figure. The one may look, because of the neck and extra metal, similar in size to that of a 7.62X25, but the stamping would indicate otherwise. It could be stamped wrong though, but I doubt it.

I have no clue. Maybe send the pictures (both of them) to CCI, tell them you found it on/at a range and your at a loss as to why the extra metal and neck that would appear to be in the one on the right and see if maybe they'll reply and have an answer?

Other then that, I haven't a clue anymore. Also, I suppose now that it's evident both are indeed .40, what is really throwing me off isn't exactly the fact of the extra metal, it's the appearance of the neck. Because if that is indeed a neck, then that would explain the extra metal.

What I'm thinking now, is if someone didn't try to experiment with the .40 round and try it in a necked round? Is that even possible guys?

JAC, what round is the one second from the left? Kind of close isn't it?

And after seeing the picture you posted, and the assortment of similar sized rounds/brass, add to that the mentality of some, anything is entirely possible? lol

One last observation I'll make. I just noticed in the very first picture of the round zephri posted, the casing on the right, upon a closer look, appears to have stretch marks in that upper/extra metal section?

phoenix79 · 04-08-2008, 09:57 AM

I'm going out on a limb here and say that it looks like the case expanded into the throat/barrel upon firing for some reson. I'm thinkng that the part that looks like a neck is where the throat of the chamber sizes down to the diameter of the bullet. Maybe there was something stuck in the barrel that caused a gross overpressure causing the aluminum to expand more than normal.

GlockMeister · 04-08-2008, 10:03 AM

But then if there was that much over-pressure, wouldn't there then be other signs of same?

phoenix79 · 04-08-2008, 10:15 AM

Look at the primer shot again. See how rounded it is on the sides? Zephri, does that primer protrude at all? It looks like it may have expanded backwards but since it was stuck in the chamber quite tightly, may not have been able to actually move backwards out of the case because of the boltface.
