    I was loading some 32-20 brass. After sizing I noticed this mark on the brass. I figured the insides of the die somehow got marred. If so, is there a way to reverse the damage, if not, does it weaken the brass?

    Thanks,
    Steve

    Why was this submitted as an article and not just a regular post?

    There is nothing more to read... you just added a photo.

    Dirty dies will do that. Clean them.

    Hard to tell but looks like you got grit inside the dies. It is why we always want clean brass going into a die, especially ones without carbide sizing rings. You can polish the die out using Fitz on a cleaning mop.

    If new dies, I suspect residual metal filings from fabrication. I have seen that in dies before. Adhered to the preservative oils applied at the factory.

    I forgot to lube a case once. It didn’t get stuck, but it came out looking exactly like that.

    Dosent appear to have hurt the brass much. Check them again after tumbling them. Clean your dies. Hit the carbide sizer with a little carnuba wax after a flitz polish job, should be ok after that.
