I do reload 9mm, but I have more than I will ever need. So I have it cleaned and polished and in a couple of gallon ziplock bags (it really doesn't take up that much room) and I don't pick up 9mm anymore. Unless it's mine that I just shot, or if I'm picking up .380 brass and some 9 gets mixed in.
If nobody else wants it, you can sell it as scrap. I'm not sure I could bring myself to do that.
