First make sure your gun is safe, remove the bolt and clean your barrel from the chamber to the end of muzzle. Clean the barrel using butchers bore shine until a patch comes out white. Run a total of 5 separate patches soaked with denatured alcohol through the bore and let dry for 30 minutes. Insert a cleaning rod with a jag and a dry patch into the neck of the chamber. Make sure it will stay there through the next process. Now using another cleaning rod, install a patch that has been coated with spray moly aerosol lube from the muzzle end. Run the patch until it comes into contact with the clean dry patch in the neck of the chamber. Do this 10 times. Remove the cleaning rod from muzzle end of barrel. Now push the clean dry patch in the chamber on out of the muzzle of the gun. The bore is now coated with moly lube. You should only have to clean your barrel once in 50 shots if using moly coated bullets. In my 30.06 this will increase muzzle velocity 175 feet a second. With 5 inch high at 100 yards, muzzle velocity at 3400 using a nosler 180 grain ballistic bullet in a 30.06. You will be dead on at 500 yards, and with scope mounted axis of scope 2.25 inch above center of barrel
