I recently acquired a ton of 40 S&W brass. Some regular brass and a lot of it nickle plated. My questions are - 1. When do you discard/recycle your brass? I have a few casings that have very small dents and dings on them. Nothing major, just small dents. Would the small dents/dings mean that the casing is weak in that spot? 2. I have some casings that are obviously beyond repair. The mouth is dented severely and there are major dents on the casings. These I know to throw into the recycle bucket. (This really isn't a question.) 3. Some of the regular brass I have is discolored, I.e., dark in color but looks great. Just discolored. Would this be O.K. to reload? 4. I have some brass of both categories that have major scratches on the outside walls. Is this a sign of wear from previous reloading and shooting or is it just from normal wear? 5. Do any of you guys and girls separate your brass by head stamp? I have a ton of Speer nickle plated brass and a few Federal and Winchester nickel plated brass. As far as regular brass I have a lot of Winchester, Blazer and PMC. I have a really bad case of O.C.D. when it comes to things being organized. I was just curious if anyone keeps they're brass separate from one another according to head stamps. Sorry for so many questions. I have been reloading for about a year. It is a wonderful hobby that I love. Thanks in advance friends!!
