They offer brass to me whenever I go to the range. I never though about recycling it, but I though about collecting it. I don't shoot any .40 S&W or 9MM-P, but the semi shooters just litter the stations with that brass. I figure if I decap it and throw it in a polisher, I have a bargaining chip in case someone wants to trade for something else I can use.
I'm a wheelgunner and a reloader, so I keep all my brass. Isn't it amazing how people just throw it away?
