My Aunt had some old .32 acp kicking around that she asked me to get rid of. It's pretty nasty, corroded and discolored. I don't think it's safe to shoot.
So, what do I do with it?
Any police department should accept it for disposal, just call whoever is closest. I grew up near the new troop a, closest leo office to me, so we took some there. I assume sheriff and city would do the same.
If you're near colfax, a company called "clean harbors" is apparently the only place in the U.S. that commercially disposes of ordinance, projectiles, etc, according to the epa.
