I just found quite the stash of ammunition while going through an old storage room and spent most of the afternoon sorting it. Among the lot was a pack of 10 7mm-Mag cartridges that are quite corroded. This might be a silly question, but what do I do with these? Is there a reasonable way to clean the corrosion? If not, how does one dispose of cartridges they don't intend to shoot? I've never had the need to throw away ammunition, so I've never given it much thought.
