Had what i *think* was an overcharged round, any thoughts?

[zWarlord]

Ok guys i am a little stumped as to what happened at the range with one of my rounds (american eagle .223 out of an M&P15 PSX)
When i fired the round the bullet went downrange but it just felt wrong, i almost thought it was a squib cause the action didn't cycle.

- The case didn't extract probably because the bolt didn't unlock all the way. - The primer had come out of the pocket and bound up the between the lugs somehow (the cup was torn apart quite badly, almost to the point of looking like it unrolled.) It was quite hard to get the bolt to unlock all the way.
- The primer was NOT pierced.
- When the bolt unlocked however, the case remained in the chamber.
- I can see on the case bottom that the details of my bolt face has been "stamped" into it. (extractor etc...)
- Plenty of black in the primer pocket.

So, i *think* it was a slightly overcharged round. If you guys can give me any more insight based on that info please do as i'm not that experienced in the AR platform.

I cant see any visible damage to the bolt or any of the other surfaces, but
i'm gonna take the rifle to a smith on Tuesday along with giving American Eagle/Federal a call.

Thanks in advance guys.

Extra info as requested:

- Never shot any steel ammo throgh this
- Weapon cleaned after every range trip
- Less that 100 rnds fired before the problem (same ammo)
- Rife still operates flawlessly, not adverse effects
- No bulging or distortion of the bore

-EDIT, PICS ADDED-

The top pic clearly shows the imprinting of my bolt to the case

Wow weird... I not sure but I agree with you sounds like a bad round but let me ask you this... How many rounds had you fired before this with out cleaning the rifle?

[zWarlord]

Gets cleaned after every trip to the range. I had fired less than 100 rnds before the problem.

Ya never mind. I saw a glock blow up shooting dirty wolf ammo. The ammo literally clogged the barrel up so bad that it over pressurized the gun after so many rounds had been shot through it. Luckily no one was hurt.

How exactly did the barrel get clogged up? What clogged it up?

To the OP. Did you remove the case? Can you post a pic?

[Mr. YACYAS]

No I didn't take any pics. It wasn't my gun and I didn't have a camera on me. I was there shooting my XDM and the guy was a few lanes away and had put quite a few of the steel case rounds down range. Well after it happened I kinda kept my distance but my friend owns the range and told me thats what happened later after the guy left with his pieces 'o Glock.

[agalindo]

Well the pic request was for the OP and his AR thing.

As to the Glock thing. There is no way that the bore could have gotten clogged up by shooting steel cased ammo. Steel cased ammo is not any dirtier than WWB or S&B or UMC.

[Mr. YACYAS]

I don't know those steel case rounds tear chambers up. With excessive residue in the chamber and a weakened chamber I can see it.

[agalindo]

Those steel case round do not tear up chambers, it's a myth. The steel used in the cases is much softer than the metal used in the barrel. There's no way that the chamber could be weakened by firing steel cased ammo.

[Mr. YACYAS]

Ya and is much harder than brass. I would debate you but if facts are meaningless I won't bother. Regardless, its still a poor quality ammo and I highly doubt that it was the Glocks fault for what happened. I won't use it. If you want cheap ammo buy aluminum cased Blazer.
