If you find that your cases are being scratched and scored, you are able to correct it. Take your die apart and clean it with any available solvent, we use Hoppe's #9. Looking inside the die, you might be able to find the source of scoring. Take some fine grit sand paper and a wooden dowel and polish off the deposit. Be sure to lube the cases before trying the die again, even if they are carbide. Sometimes you are able to flake off the brass deposits using a stiff wire brush as well.
or
You can ship the sizing die back to us with sample fired cases. We will polish out and resize. Make sure to be using Lee Case Sizing lube to prevent this type of galling.
