corroded cases

tango2echo · Aug 27, 2009

I have a bunch of .300 Win Mag brass that my father had back in 1967. It is new, unfired brass. It was stored in styrofoam blocks inside of paper boxes. Much of it is corroded. (I recently discovered a box of reloading equipment that he didn't know he still had)

Can this brass be saved or should I scrap it? What about the brass that only has a few small spots of corrosion? Has the corrosion weakened the cases, or is it superficial? What would be the best way to "save" it, if it can be done? At this point it has been in the tumbler for about 45 minutes.

Thanks,

With a high pressure round, it's not safe to load brass with that kind of cancer on it. Just scrap the brass (scrap prices are up again) and use the money to buy new brass.

Hope this helps.

That brass is NO good......period.

"Spots" are one thing, those cases have Cancer of the terminal nature.

Cartridge brass is 70% copper and 30% zinc. Somehow sulfated compounds with the assistance of water/moisture, made contact with the brass, resulting voltaic cells leeched the zinc and reacted with the copper from the brass.

The bluegreen color of the corrosion is coppersulfate and the whitish residues are some salt of zionk. The red areas of the cleaned brass show that the zinc content has been removed to show the redish copper. The strength of the brass has been compromised. Scrap it.

Tarnish is okay. As others have said, green and fuzzy is scrap.

Compared to surgeons re-attaching your fingers, brass is cheap as dirt. SCRAP it!!!

corroded cases

What would you do?

Scrap all of it.

Shoot it anyway.

Save the least corroded and shoot it.

Try to clean all of it up.
