Here's my bore cleaning method . Two patches with Sweets down the bore , let sit for about five minutes . Next brush the bore with a bronze brass brush and Butch's bore shine , two strokes for every shot you have put down the bore , use a bore guide and don't let the brush exit completely , that will save the crown . Push the brush down the bore from the breach slowly , this is not a race , till the brush just begins to exit . Now pull it back and repeat this once for every shot down the bore . Run one patch with hydrogen peroxide after brushing , this is going to foam out the copper and powder fouling and neutralize the solvents . Dry patch till the bore is completely dry and there is no more black , blue , or green . Otherwise you will have to start over . Next don't forget to clean the chamber . There will be a tough ring from powder fouling that will form at the end of the chamber . Remove this by twirling a larger diameter brush in the chamber ( add one caliber larger diameter ) with Bore Shine . Now dry the chamber with several patches . If you don't remove the chamber ring , you will eventually have pretty wacky shooting rifle . Keep in mind that factory bores are very rough , and they will require more frequent cleaning . Finally use a good oil such as Butch's gun oil to protect the bore . Always shoot a fouler through the bore before shooting for score or hunting . Most gun owners never put in enough work to clean their rifles properly and have no way to verify their cleaning process . This process has been verified by a bore scope and years of experience shooting paper and game ( thousands of rounds a year ) ! Never leave anything in your bore overnight !
