I bought a parkerand hale 303 a few months back and recently went to clean it and all my patches are comeing out a greenish blue color. I have now idea whats coing on cuz i'm doing the samething i do on all my other rifles and none of them have this problem. I'm useing hoppes #9. If anyone can give me an idea to what is causing this and maybe how to fix it that would be great.
