Thats good ammo no matter how you look at it. I had someones Y2K stash of 230 gr FMJ 45 ammo that had been flooded in his crawl space and it looked terrible. We tumbled it and then broke the seal by seating it slightly deeper and then pulling it all down. Most of the brass was usable and all of the bullets were.
The shot can be recovered and either reloaded, or used as a hardener with casting boolits.
