+3 about that. Only my own stuff.
For a few dollars, if you reload, you can buy a bullet puller and dismantle those rounds. It's a bit of work but you could harvest the brass, and the bullets.
Of course, there's no way to know how many times those cases have been fired....but it is an option. In this day and age, with brass and bullet prices as high as they are, it might be worth doing.
