    This happens from a few possible causes :

    1. Brass failure due to repeated FL sizings, and finally gave out ( scrap the lot ! )

    2. Brass failure due to manufacturers error ( I've had a few WIN pieces do this on trigger pull one )

    3. Enormously large headspace issue ( it would happen on dang near every shot )

    4. Enormously large powder charging error.

    5. Some combination of all of the above.

    We need a little more data.... How many times fired ? Charge type ? Brass type ? Bullet type ? Firearm might even be useful.

    Welcome to The High Road. I know you're new, but don't be afraid of getting flamed here. It's called The High Road for a reason.

    Please, post as many details as you can. It's really the only way people can help.

    It's pretty hard to help you if you don't post any details.

    Welcome to THR.

    Question for the OP?

    What case gage are you using to measure your resized cases?

    What are you using for a trimmer? I noticed that when I use the CTS trimmer that I just purchased, and love by the way, there is a wear spot after trimming. Right about where that separation is.

    this will happen after enough full-length sizings of any bottleneck case, but .223 gets thin further up the case body than most others. like was said earlier, google "case head separation" and you'll find all the information you could want.

    If that was from one time of over pressure I'd say the bolt was about to give.

    RockCreek: Welcome to THR. As for your 2 piece case; that scares me and I ain't scared of nothin! I'll leave diagnosis to the wise ones here, but please figure it out before touching off any others from the batch.

    Anyone else notice the unusual crimp around the neck? I'm used to seeing factory crimps on .223 brass but it's usually right at the case mouth.

    I would say the marks around the neck was a crimp at one point. Could be wrong. How many firings and all of the info above that was requested would really help. "flaming" is not acceptable here and most are here to help you ensure this never happens too you again. Just need all of the details to tell you what went wrong.

    I agree, it would be good to hear a little more on the history of this case. Number of time its been resized, what it was resized with, trimming that's been done, gun details and what happened prior to it parting. I could guess on a couple causes, but the photo isn't enough.

    Related question from a rookie: Is it common to see case head separation that far from the case head?

    Little Info

    This is once fired reconditioned brass I received from a top brass it was already deprimed and swaged. My case gage is a dillon. using ACC 2230 at 25.5 grain.
    was loaded on a dillon 1050. shot by a ar15 we had three of these out of 1500 bullets.

    Hope this was all that was asked.

    When did it happen, on firing or did it pull apart in the sizing die? It looks pretty clean to have failed on firing.

    Is Clyde the OP? If so, please don't post under different aliases. One is plenty.

    Clyde or Rockcreek - whichever of you is the original poster: What made you think you're going to "get flamed" for posting this question in this forum?:confused:

    There is a lot of fun flaming that goes on here. Must of the time it it's from people that don't know what they are talking about also.

    Something other than "classic head separation" is going on here. I've never seen one so far
    up the case -- and with no soot marks. (If this was once-fired machine gun brass, though,
    that might be where then case stretched. Someone else weigh in here.)


    I'd "paperclip test" the remaining empty cases.

    Sasquatch: That neck (crimp?/constriction?) ring bothers me too.
    RockCreek: Can you shed some light here?

    One is more than plenty. Duplicate registration is specifically prohibited....

    Anywho, I agree it is an odd case of separation. It almost looks pulled apart, on further inspection.

    If you had three failures out of one round of shooting- I'd be dispensing with the rest of that brass... something is seriously wrong.
