A few years ago I purchased some 7.62x51 surplus ammo to plink with. I picked out the stuff that looked funny and shot the rest. Fast forwarding, I now have 50 rounds of this stuff that has blue residue and what looks to be scale rust forming. I refuse to even consider shooting this. My problem is that I don't know what to do with it. How should I dispose of it? I don't want to just dump it in the trash. I would give it away if someone would take it.
