    PLEASE ADVISE IN RELOAD OR NOT

    Just finish resize and clean my brass and found this "funny" marks in the neck/shoulder area, kind of a sign of it will split if i do reload it once again.
    Question is: is it a sign of fatigue?
    This brass has been reloaded for 7X and mostly neck sized (only 2X full sized) and i have annealing for 2X now(the second time just now).

    Thank you in advance.

    P.S.: the vertical marks are from the resizing die, the main thing isa the "ring" in between shoulder and neck.

    Looks a bit like a crush possibly caused by insufficient lube on the case necks the marks on the neck tend to point that way. Try chambering one

    I hear you, but no, it isn't crushed, it is more like "scraped" down where it get a little "material loss"?! If you can imagine what i mean…
    Thank you for the reply.

    Neck bushing in wrong way around, ie no chamfer on neck bushing

    @7mmsaum,
    The die is a RCBS neck die, no bushing that i can record of.

    Couple of new photos as example…

    It if they chamber without restriction which I am sure they will, it is nothing to worry about. it should headspace further down the shoulder and unless your chamber was cut with a spec reamer you will have plenty of neck clearance.
    It is likely just from the bushing or die displacing flowed brass.
    Pretty sure I get it around the same amount of firings.

    If you only have to FL size 2 out of 7 loads you are sweet.
    Just make sure those rings are not on the inside of the neck.
    Before necksizing, a projectile should slip in and out unobstructed.

    You may need to clean your die as well but they look fine to me

    The surface of that brass is way too rough for my liking

    When the sizing die was made id say the reamer has "chattered" when finishing the cut, another new die will solve the problem

    Polish that die out and you will lose what little neck tension its already achieving.

    The Polishing process wont be uniform either,

    A sizing die should NEVER move brass like a dozer blade, if it does then its lacking a chamfer and should be replaced.

    Its a sizing die which is required to gently size down the neck dia of brass, not remove metal to make the necks thinner.
    Your neck tension will be uncontrolled and lessen every time the brass is forced into that die

    Bin the die, otherwise all your brass will need a neck turn to uniform it and a tighter bushing in a bushing type sizing die to restore the neck tension value that you used in load development (2-8 thou)

    The die is quiet new, less than 300 rounds thru it, how I need to "dump" it in the bin??? I thought a die would last a while

    Was the last die you used before noticing those marks on the neck the neck sizing or the full sizing die ?

    Should not look like that, the neck is a fairly critical area for accuracy.

    Unscrew the de priming rod from your die(s), and give the inside a good clean with something like crc and use an earbud. Shine a torch inside to check it is all clean, smooth and shiny.

    Has anything else changed in your reloading routine if this did not happen before ?
