I've disposed of my share of bad ammo in my life. I'm too scotch to throw away perfectly good bullets if they are such and can be pulled. As for the rest, fertilize the lawn with the powder and toss the remains in the trash. Heck I've also gotten rid of some sick odds and ends by just putting them in the garbage and set out by the curb on Thursday mornings. Certainly some corroded ammo isn't a hazardous waste, per se, and who among us has never ever consigned something to the garbage that maybe we shouldn't have anyway?
Taking it to the cops would be the last thing I would do. In my neck of the woods, I would have to play Twenty Questions about where I got it, why I got it, and do I have any more. Bingo, I'm on their radar. Easier to just dismantle it or dump it.
