  1. Soak a suitable sized Montana X-Treme patch in Copper Killer and mount on a jag.
  2. From the receiver end (and preferably through a bore guide) push patch through the bore allowing it to fall off as it exits the barrel. Repeat with a new patch. For maximum results allow barrel to “soak” at least 15 minutes before continuing.
  3. Soak a nylon brush in Montana X-Treme Copper Killer and brush the bore approximately 20 times.
  4. Soak a patch in Copper Killer and run through bore one time.
  5. (Optional for stubborn copper deposits) Apply a liberal amount of Montana X-Treme Copper Cream to a tight fitting patch and work through the bore several times.
  6. Wet a patch with Copper Killer and run through the bore.  Repeat this step. If fouling is still present, repeat steps 5 and 6 until fouling is removed to your satisfaction.
  7. Run two dry patches through the bore.
  8. Protect the bore by adding a small amount of Montana X-Treme Bore Conditioner to a patch. Run through the bore several times. Ensure that you do not leave a heavy amount of oil in the barrel.
