    Default Green Necks

    I have some older loaded ammo with green necks. I can't think why the brass would corrode only there, but it has.

    Two questions:
    1) If I wipe the corrosion off with solvent and a rag, will it still be safe to fire? (I'll get all the solvent off the brass before chambering it, of course.)

    2) Why just the neck?

    Default Corrosion

    The green necks may be caused, by exposure to nitrates. If the round has been chambered and removed witout firing the nitrate residue in the barrel can cause the brass to turn green. If this is ammo which has been kept clean and dry. I would simply wipe the corrrosion off and bang away.

    Is it factory loaded? Or perhaps barnes copper? The color may be caused solely by the bullet jacketing. Just a thought

    If the grean is on the outside and can be cleaned off, it shouldn't be a problem. If the neck is corroded on the inside, you could have alot more resistance when the bullet releases and hence raise pressures. Also the neck could be compromised and crack on firing.

    I'd advise pulling the bullet on one round to see if there is any internal corrosion on the round before firing any. Better safe than sorry.

    Handloaded. So the brass has been exposed to the chamber, but only some of the cartridges have green necks. Others have no apparent corrosion.

    Lead-core, copper jacket. It's Win brass, if that means anything to anyone...

    Dude,

    It's not worth the risk, ammo is cheap. Your life, eyesight and limbs are priceless. Throw them away and you will for sure see another day to shoot/hunt again.

    Good Hunting,
