    Place: BuCor Range
    Date/Event: Thursday, May 11/06-Lag-Psg Practice
    Pax: Lito P., Jason, Teody Salas, etc.
    Scenario:
    After a run in one stage, definitely I had to "unload...then show clear". Ayaw mag-extract nor mag-eject ng shell. HINDI MA-COCK! IT IS AF IF NAKA-TRIGGER LOCK...BUT NOT. I had to fire the last ammo.
    It happened to about 3 or 5 ammos. THEY, repeat THEY, ALL passed through the case gauge. Teflon coated.
    Jason, Lito, Teody and others TRIED in their respective guns. Same thing.

    QUESTION:
    Fellow BoGs, WHAT DO YOU THINK MAY HAVE HAPPENED?

    Addendum to previous thread:

    Crimping is A-okay.
    Shell is once-fired kaya okay pa ang rim.

    Bad Ammo , baka hindi na once fired yung brass Sir.

    minsan kase pag sinabing once fired ang brass na nabibili dyan , it means once fired in a week for so months.
    pero kung ikaw mismo bumile ng brand new brass at ikaw ang nagpa reload, cant think of anything.

    only thing i can think of is "buntis" yung ammo... what brand of case gauge did you use? if you have some of those ammo left, try to guage it into your pistol's barrel chamber and see if it all fits easily.

    Toxic & Judge,
    Thanks mga Pre.
    They passed through my own and Lito's case gauges. Don't know the brands.
    The shells were actually once fired-Federal that came from USA. That's according to him who sold to and reloaded them for me. He got the shell for "scrutiny".
    Offhand, I can also and ONLY think of "BUNTIS" na shell as the culprit.

    Judge, nasabi sakin ni Django na LAG ka rin. I think I used to see you and Tigra every month-just don't know who is who among you two.
    Sana di mapostpone clubshoot tom.

    Judge, kayo nga yung dalawang magaling. One fires a Glock (.40 ba o 9mm) the other is naka-open. I watch both of you and admire na sana maging ganoon din ako someday.

    Ako yung LAG na 3 Ms: Matanda, Maliit, Madalas Kulelat sa Clubshoot.

    Hehe! See you.

    Once fired brass that come from the States are usually taken from public ranges/gun ranges or gun clubs. I've seen barrels (drums) of brass just laying around the gun club.

    They sort the brass by caliber, and brass mix-up is not uncommon. I've sorted a bucket of brass that my brother and I picked up, and I've mixed .38 Supers with 9 x 21s and 9 x 23s.

    Also, a friend of mine got about a thousand of once fired 9mm brass. When he had it reloaded, the reloader returned at least 7 9 x 21 shells that got mixed with his 9mm shells.

    How about using your FA chamber as gauge instead of using the regular case gauge just like JuDGe said. The chamber might have tighter tolerance.

    Hi.

    I would have replied earlier, but downed power lines yesterday
    prevented me. As JuDGe, toxic and isuzu have already posted, the
    non-extraction is indeed most easily explained by case deformation:

    Brass is annealed the opposite way from steel: heating and immediate
    quenching softens it, and for cartridge casings the firing cycle can
    come close to approximating the annealing procedure --extreme heat
    and pressure, followed by rapid exposure to much-cooler air (the very
    thin section of the brass aids rapid cooling). Casings subjected to
    this repeatedly tend to retain later deformations caused by stress.
    They expand to hug the chamber walls, which is good, but then fail to
    relax the hugging, which is bad.

    In fact, used casings are often Teflon-coated to compensate for this.
    If the casing is going to be tighter against the chamber walls, the
    Teflon reduces friction to help with extraction... but if the case
    wall is already so weak it's going to mold itself permanently to the
    chamber interior, Teflon ain't necessarily gonna cut it.

    However, the above applies to casings after the bullet has said bye-bye.
    You seem to be describing a failed attempt to rack out an unfired
    cartridge.


    You furthermore seem to be describing a similar unfired cartridge
    failing to rack out of Mr.Barretto's, Mr.Pible's and Mr.Salas' pistols.

    If the cartridge was deformed before firing, your case gauges would
    have caught it. Even with a tight chamber involved, as vega is
    suggesting, the incident would require that ALL the pistols involved
    had abnormally-tight chambers, which is unlikely.


    A longshot:
    If you never had problems prior with the batch of reloads in
    question, consider that Thursday presented a spike in humidity:
    all the prior scorching weeks were comparatively dry (RH 60's to 70's
    while Thursday was into the high 90's and still as hot). Humidity does
    some funky things to both dry and wet lubes, as well as residual gum
    and carbon --and the chamber walls are better protected from burnout than the barrel interior.

    If this happened between 1:30 and 3:00 in the afternoon, let me know.
    Barometric pressure was going a little nuts around that time.


    This inability to cock the hammer(?) puzzles me.
    Especially if it applies to the other three pistols as well.
    That's why I asked if the platform was a 1911, to be sure. After
    every shot, the hammer should remain cocked via slide cycling, so
    what was there left to cock?

    The 'trigger-lock'(?) I presume to be the thumb safety. It is
    the thumb safety's operation that is dependent on the hammer
    being cocked, not the hammer's cocking that is dependent on
    the safety being off.

    Are you instead referring to 'racking' the slide, perhaps?

    +1, FA chamber is the best gauge, cheap pa:cool:
     
  14. Sir, IMHO if the ammo passed the case gauge and actual chamber check I think the diameter of the ammo is not the culprit. I would like to suggest if you can check the OAL(over all lenght) of the ammo or the case. If the ammo is a tad longer than the specs or chamber it might get stuck on the "rifling" of the barrel. This is pretty common in rifle ammo but it happened to some of our club members using a.38super and .40SW ammo. Check the problematic case and if there are "rifling" marks the OAL might be longer. I hope this helps. :)

    Pogi pare,

    forgetaboutit. As long as it chambers ok na yan just shoot it. It will extract on its own:supergrin:

    If it does not guage then there is a problem. It guages then its ok. It fed on all of our pistols just fine. Baka yung teflon was a little tacky thus it stuck a little.

    In my opinion just shoot it. Its something less to think about:)

    If the ammo chambered ok (and can be rechambered and extracted again with no hiccups) then another thing you might consider checking is extractor clocking and/or disconnector binding.

    Extractor clocking isn't much of a problem if the gun is extracting reliably. But when your disconnector binds the slide (refuses to be pushed down), then you have a much more serious problem with your fire controls. This is potentialy dangerous and should be looked up ASAP. ;)

    You don't happen to be using a 4-finger sear spring, do you?

    Yep , happened to mew too , especially if mejo madumi na yung dulo ng chamber
    Pero I'm wondering why the gun wont cock
