Death is Preferable to Communism.
Got some 45 ACP Brass from a buddy of mine. Most were high polished but some look like they were copper washed. Chemical cleaning perhaps? And will this affect brass strength and integrity?

They came out with a copper look to them. I went to another forum and that's the first error I saw. Shouldn't heat them over 150 degrees.
