Thread: Resizing after pulling heads?

  1. #1

    Resizing after pulling heads?

    Should you re-size you cases again after pulling the heads off?

    you can get away with it,just seat one and try and press it in by pushing it against your reloading table,I did some the other day,they work perfectly

    Why re-size if you haven't fired the round? atb Tim

    depends on the amount of neck tension your die gives,most off the shelf dies will give quite a bit so pulling a bullet carefully and reseating another isn't a problem,if you use busing type dies where you only use 1 thou of neck tension pulling and replacing a bullet isn't such a good idea as the tension on the neck will be lost

    What about the unfired primer?? Surely, unless you take out the pin from the sizing die, something's gonna go bang!

    Remove the de-capping pin first or remove the complete spindle if you are using a bushing die. Regards JCS

    Having had to deprime many live primers I have yet to have any detonate and all have been re-used without fail. atb Tim

    dies don't give neck tension
    necks do, thick necks, thin neck, hard necks, softs necks, long ones short ones

    unless you are running 30mm cannon shells pretty much all necks will expand to accommodate the bullet and leave you with a neck bore 1-2 thou smaller than the bullet when pulled.

    unless your brass is very hard you should be able to shoot them without resizing BUT....not all bullets are the same size.
    Remove an oversized one and refit an undersized one and you could probably do it by hand!

    pull your decapper or get a collet die or a crimp die

    If you want to try reloading & seating the cases after pulling a bullet from an unfired round, it may be fine to do so without re-sizing the case. Just test & see how well a bullet holds in place after it’s replaced, however, I think you’re unlikely to retain consistent neck tension.

    In my view it’s best to start over. But, if you choose not to, the primer may be saved as JCS said, by sliding the de-capping rod & pin upward away from the case head, so it can’t de-cap the primer, but the expander ball can still function correctly on case extraction from the die. So you end up with a correctly sized case & consistent neck tension with the primer ‘saved’.
    You could potentially doing this, end up with unreliable rounds due to contamination, whether from case lube or other matter.

    If you pull all the bullets from the selected cases, my view would be to size as if the case had been fired, but carefully & gently while re-sizing, de-cap the unfired primer.
    This can be done in relative safety if you must do it.

    The best alternative is to just fire off the ‘primer only’ cases and start a ‘fired case’ re-sizing scenario correctly.
