Kaboom! - Almost ?

[3006mv]

does a .40 in a .45 magazine chamber in a .45?
will it fire? if so then that is what happened

[Carcassonne]

The only answer that is physically possible is that you fired a .40 in a .45.

That is what it looks like to me.

I have a 40S&W case sitting next to me that looks the same. It was shot in a 45ACP barrel (Glock 21). I was shooting 40S&W in my Glock 20 10mm. I switched to my Glock 21 45ACP, but accidentally put in the Glock 20 magazine.

LOL.
Wait until you read the rest of the thread...

Yep the internet is full of experts.

[bruce381]

yeah i got a 40 shot in a 45 that looks excatly the same

[VoR]

Oh really????

There were quite a few different theories. Let's recap the posts:

cwilliams - is that a 40 case?
Zabmle - looks like 9mm
Cokebottle - 9mm slipped in the batch
cwilliams - 9 through .40 and .40 through a .45
scobun - .40 in a .45
Orangeusa - bigger than .45
stilly - .40 resized to 9mm
stilly - doubled up on the .40 resized to 9mm theory
bsumoba - wrong caliber chambered
romukom - wrong caliber stamped on the brass
mhmagee67 - fired out of battery
opos - 9mm marked as .40
f4tweet - out of battery
pdq_wizard - 40 in the .45
Eurphoria - glock hater
Eurphoria - still hates glocks
cwilliams - out of battery confirmation, yet still goes with the evidence of .40 in the .45
ar15barrels .40 in the .45

I did consider each post and knew the 9mm theories were incorrect. Having read and theorized on my own about all the Glock kaboom hype I was pre-dispositioned to think that somehow the Glock was involved. It was .. it was at the range too. It wasn't until the .40 in the .45 theory came along, that I realized that I couldn't trust my memory and needed to believe the evidence in front of me.

But you also mentioned that you pulled this out of your .40 glock -- how did you not remember that you manually cycled this out of a .45?
Bizarre to say the least that you just happened to leave out shooting a .45 and also which gun you pulled this out of.

I typed it up as I recalled it. Obviously my memory isn't photographic. The great work of the Calguns internet sleuth team were able to refresh and verify what happened and I admitted that. I bet you're surprised I was able to remember how to start the truck and drive home too.

Lol...fair enough. Sorry if my post was harsh

Look, the diameter at the front of the case is from the barrel chamber. If the case is .40, then you fired it in a .45 barrel (Not sure of any other >.40 auto pistol barrels out there you could have popped it into). There is NO other option.
Now, if the case head area was expanded, then you would have out-of-battery or other issues, but in this case, you fired it in the wrong barrel.

Background:

I have been reloading for about 20 years. Never any issues with my ammo.
About 15,000.45ACP rounds loaded, 10,000 9mm rounds loaded.
New to 40 SW and familiar with the high pressure

This was a reload
5.3 grains of HP38. 165 Grain RNFP Plated Extreme bullet.
Winchester brass.
Winchester standard primer
OAL set to 1.135 in

What happened?
This was one of the first 100 of the 40SW reloads I did, and somewhere around round #50 shot in my G23.

The shot was normal as I saw a hole in the paper after I pulled the trigger.
The experience was not normal as I didn't feel as much recoil and I'm 99% sure the slide did not cycle. I manually cycled the slide, and this is the brass that was ejected.

Here is my suspicion on what happened.

1. In the bottom photo you can see the mouth of the case is dorked.
That was from the initial setup of the flaring and was obviously too much for the seating die where this dork took place.

2. The imperfection of the brass prevented the round from fully entering the chamber.

3. While not in full battery, the gun still fired while not fully supporting the case. (This doesn't make sense as 3/5 of the case is about the size of a .45 acp case and not a 40SW case.)

Note:
There was no hot gas released on the outside of the gun
There was no "kaboom" as seen on other internet threads
There was no fouling of the magazine, or magwell.
Subsequent rounds fired fine.

I'm temped to now have the barrel tested for cracks.

Your thoughts?
*** UPDATE ***
[B]The answer has been identified and accepted as a .40 in a .45 barrel

(I am glad that I am not the first to catch on to this.)

No I am sorry. THAT is not the correct answer for this scenario. AND if it is, I want to see this magical .45 barrel in a G23.

You stated that THIS was the brass that was ejected from your G23 and that your G-23 was a .40 cal. Correct? So then how did a .45 caliber barrel get swapped in for this one shot?

This thread has turned into YAHOO ANSWERS it seems. Either you did something or you didn't do it. Although I DO agree that the brass looks like it DID get fired in a .45 chamber. I mean, the evidence is right there, AND also, since we are going that way yes, it was most likely NOT fired from a Glock of any kind based on the primer strike. I was giving you the benefit of the doubt and trying to find out what could have happened since there was NO .45 allowed in the scenario. I apologize. It seems that you DID indeed make a mistake in picking up the brass from another person's gun because you stated you were shooting .40 out of a .40 cal firearm.

So anyways. It seems that April has come early for a few of us. I guess from now on when people post things and say it came from doing one thing, I can reasonably assume they have no clue as to what they are talking about and can just give input based on what most likely happened whether they said it did or not like some of the other folks here are are clearly more glued to reality than myself.

So based on this new "accepted answer", you DID NOT eject this brass from your G23 and you did NOT reload this brass in the first place and your gun did NOT fire this case out of battery.

This points to another issue that you possibly now have. You may have other rounds that you did not charge correctly so I would certainly proceed with caution until you examine your reloading/charging methods and while you are at it you might also want an eye exam; they are only $99 from Lens Crafters (less if you have vision in your health insurance plan) and could save you from a much more expensive mistake in reloading further down the road.

The only reason why I even gave such bat-**** crazy possibilities was because you stated what had happened without any doubt.

Yawn... Being trolled has made me hungry. I am gonna go get breakfast.

No need to respond to this post OP, let's just lock the thread and let it sink to the bottom of the ocean...

And yet they continue...

And yet they continue...

Hey I gave OP the benefit of the doubt that he knew WTH he was talking about as I give others that same benefit. Clearly I made a mistake. Damn and I was so close to being perfect too...


Yeah look at that, I can not even walk on water anymore unless there is cornstarch in it...

[Cokebottle]

I bet you're surprised I was able to remember how to start the truck and drive home too.

Sigh.... You needed the hide-a-key, didn't you

[curtru]

And if you look at the picture that shows the off set primer strike you can also see it bulged to fill out the unsupported side... lol glad you are safe

The OP has his answer, so there is no reason for this to remain open. Glad you are ok OP.
