Corroded Brass???

[Josh Smith]

Hi Folks,

I just tossed 40 pieces of otherwise good 7.62x54r brass:


No idea what happened.

These had been loaded with Varget, backed by Federal primers and firing SST bullets.

Nothing unusual.

I had them stored in Plano ammo containers, which I also tossed. The brass stored next to these, only in surplus ammo pouches, were unaffected.

These were kept in my shop, which is of course climate-controlled.

They were fired and put up against the day I'd find more of the powder I like, and that was yesterday.

I've never seen this type of brass corrosion when it wasn't exposed to a cleaner with ammonia, and it was all kept away from chemicals.

Any thoughts, folks? The only common denominator seems to be the Plano plastic storage cases. Once-fired and not cleaned that was NOT stored in these were just fine.

Thanks,

Josh

Trapped humidity, and that brass is still usable if you get it tumbled in SS pin's.

I have cleaned up brass that was out in the weather, let it spend a day tumbling in old media then change to fresh media

Josh, I would be happy to pay for shipping to have that brass. That small amount of corrosion is easy to clean.

Joe beat me to it. I'd love to have it and am sure it would clean up with ss tumbling

I have stainless pins and I might give it a go.

I found a little pitting in a few of 'em. I was going to play safe, but I posted this on several forums and according to all they should be safe.

I'll try it.

Regards,

Josh

clean them before you decide to toss or use. I got 5 gallon bucket of brass from a guy that had a water heater leak all over it. It was corroded but cleaned up. The guy was just going to toss it, he actually bought some of it back(just for my time).
