One addition is that before I oil the barrel with some rem. oil (last step before I leave it rest), I make sure that the barrel and nipple area is good and dry. If you have any moisture in the barrel before you do the final oiling I believe that the moisture will be trapped by the oil. Just something to think about. When cleaning the water should be hot as possible. I have found that the hotter and the more water you can use the better, esp. after shooting a lot. Hope this assists you.
