i have some rifle brass that has black "stains" on it. ive tumbled for a long time, and the rest of the case is shiny.

do you use "stained" brass or just toss it?

Take some baking soda and try to rub out the stain. If it does go away, examine the brass in that spot to see if it is discollered to a redish hue. If it is red, then the zink has been leached from the brass, and it should be tossed.

Stained brass...

With me it's mostly pistol brass--If the stains are just on the surface, I go ahead and use the brass.

If the brass appears to be corroded, or compromised in any way beyond the surface, that piece goes into the scrap bucket.

You just answered your own question...

Troy,
this stuff is black, and deep. took one to the buffing wheel, it just made it shiny black.
Scrap brass. Not worth the effort (buffing, Scotch-brite, Flitz, etc, etc) nor the risk of brass failure on firing. Brass is cheap, fingers are expensive. The scrap dealer doesn't care if it's stained.

Even if it's some exotic cartridge for which the brass is fiendishly expensive, I wouldn't use it in the condition you describe.

My family has a collection of .30-30 Win, .270 Win, .243 Win, and .30-06 brass that came from an old camp fire.

Every round had cooked off, and looked to have been subjected to high temperatures for quite some time.

We also have a handful of .270 Win brass that has had a huge amount of the Zinc leeched out. It is almost completely pink.

The safe thing to do, was throw it all away.

So, we ignored conventional wisdom, loaded everything up, and called it an experiment.
To date, we have lost one case due to a neck split.
The rest of the brass did so well, that it went into our general collections of pickup brass.

At least 7 of the 'campfire' .270 cases have been loaded more than 10 times. The 'pink' cases are on their fifth loading. (In our hands. The pink ammo had been reloaded before; the campfire ammo appeared to have been all factory.)



The safe bet is to throw the brass out. A dollar or two in savings is definitely not worth personal injury.
...But, brass can surprise you some times.


If it's just stained, and not compromised; load it.
