Seem's to me every serious shooter has their own method. I have broken in eight handgun barells for by contender & encore over the years and settled on this method. Assume the new barell has "crud" left behind by the maker or from test firing! With the barell off the gun and out of sight of your wife, boil a guart of water, drop a few drops of liquid detergent down the barell from the breech followed by the hot water ( hold barell with cloth covered tongs as not to burn yourself). Run a dry patch through. Repeat the process three times and finish up with a very light coat of "rem." oil. At the range, one shot, patch & solvent, clean patches (several). Fire 2 rounds and repeat cleaning process up to 5 rounds. After five, clean and lght "Rem." oil. Thats it! don't know how others feel about the process, makes me feel better plus barells are all in perfect shape. I also bought a "Bore Snake" for each cal. and run one through after each session. (needless to say, everything should be off the barell except the front sight) Good Luck!
