[QUOTE="SidecarFlip, post: 788113, member: 39764"] Green brass is caused by only one thing....moisture. It's 'rusting' in this case oxidizing. Thats also what causes your fingerprints on a case to cause the case to discolor, the moisture in your fingers plus the oil/acid in your skin. I keep my cases in zip lock plastic bags with a silica gel dessicant pack in each one. People want their expensive copper gutters to turn green, they like that patina. Not so with cases. Cartridge brass is copper and zinc alloyed together. I load them and unlike many posters, do a last tumble in a bowl tumbler to clean off the sizing lubricant and then I box them wearing cotton gloves...... and no, I've never had one ignite in the tumbler.
