For those of you who fight getting the copper out of your rifle bore, you have to try the Outers foaming bore cleaner that you can buy at Wally World. So far it is the best bore cleaner that I have ever used. You do need to make sure that you get a can with a long hose on it(just look at it and you will understand) Some come with a short hose that will not seal the chamber and will allow the foam to blow back into the action. This stuff will have your bore totally free of copper and powder fouling in 30 minutes and there is NO brushing.
