All of my brass so far has been picked up at an indoor range. A friend gave me a 1 gallon bag full of .40's that he picked up for me an an outdoor range. They came with a liberal sprinkling of sand and dirt.
It seems that a even a grain of sand sticking to a case could havoc with reloading. How is it normally removed? I was envisioning using my air compressor, but that seems tedious.
I was wondering what the normal process is for brass picked up outdoors. Does tumbling remove any dirt/sand that may be in brass?
Thanks,
Randy
