Rusty ammo

[Setter Man]

Sounds like the punchline for a bad joke, I know.

Friday I pulled out a couple of old boxes of American Eagan (Federal) Copper Plated Field loads for my 20 ga. Now, I have not touched these boxes in several years but they were the only 20 ga ammo I could find so I took them. When I opened one of the boxes I discovered that several of theem were pretty rusty. Around the primers and around the base of the brass. Some were so bad I doubt that I could even get them to seat properly in a chamber. Most were not that bad, with just a little coorsion on the brass. I cut open a couple of the worst shells and found the shot to be in perfect condition.

What say you experts? Would you shoot the non-rusted shells that are not really bad and dispose of the rest or would you just dispose of them all?

Thanks,
