45ACP range brass, I have inherited a 20MM AMMO CAN FULL of fired brass all from the same NM shoot same day, NOT ALL the same head stamps, HOW do I go about sorting this? You know how a shoot is, some of this has been walked on, has burrs from the concrete, HAS BEEN IN THE AMMO CAN PROBABLY 50 YEARS, some have little green specks of corrosion on them. OK split cases out! I HAVE a TUMBLER(steel pins)_ and an ULTRA SONIC cleaner, WHERE DO I START? I realize that some will be no good, but if I can use most of it, That would be a great benefit to my IDPA and Bullseye shooting, HOW WOULD YOU PROCESS THIS? I know it may take more time and more steps, but in this economy, it would really help a guy of modest means with his addiction.
