I inherited some old .45 ball ammo from my cousin. The ammo is corroded. Can it be cleaned (70 rounds). Is it worth cleaning or junk it?
Yes, it can be cleaned up. If the cartridges are still sealed and no moisture got inside, they will be fine. Rub the corrosion off them, or at least a sampling of them, and touch 'em off. If they all go bang, well, you know what you have. If you have misfires, very possible, I'm sure you know how to handle them.
Stick them in a Corn Media tumbler, and spin them for a couple of hours.... They will come out Bright & Shined Up...... Just like new....
If its super old stuff and has had a rough life, you might want to be carful in tumbling the ammo as depnding on the powder it may get "hotter" as the physical properties of the powder are changed and rate of burn is altered. Just be caustious and use common sense... you will be ok...
