+1 on that. I have tried both Sweets 7.62 and Butch's Bore Shine and they both work very well. A good way to see if you got all of the copper fouling out of the barrel is to look down the barrel with bore light from the muzzle end. It works even better in a darkened room. If there is copper fouling in the barrel you will see orange streaks, almost like the color of rust.
