Corroded Rounds

[valkabit]

I found a couple of corroded rounds in one of my ammo boxes (plastic boxes). The rounds are .44 Mag, with hard cast lead bullets, CCI large pistol primers, Unique powder. The rounds are about 8 years old. Out of a box of about 100 rounds, 5 rounds have a white powder on them, similar to what you see on corroded battery terminals. The rounds were stored nose down, in a basement that seems relatively dry. I've recently been using powder & primers stored in the same basement with OK results (did not chrono any rounds loaded with the old powder/primers). The rounds stored in the same ammo box as the corroded rounds seemed to shoot OK (again, no chrono). I did not shoot the corroded rounds.

Any ideas what happened?

Should I reuse the bullets and cases? (Not that 5 bullets/cases really matters).

If I should dispose of these rounds, what's the best way?

I wouldn't think that if the white powder is on the lead bullet that there would be a problem. For safety's sake, you might just want to dispose of them. I'd use an impact puller to take them apart.

it might be from the polishing solution you used when cleaning your brass

I wasn't really into polishing my brass much back when I loaded that stuff. It's pretty tarnished, maybe 6-8 loadings without a polishing. I do polish my brass now.

I'd just drop them in the tumbler for an hour, then take them out and shoot them.

I was wondering if the powder or primer could have caused the corrosion?

An Hour?? That is downright scary.
