General Firearms Cleaning

1. Soak a suitable-sized patch in Montana X-Treme Bore Solvent and mount on a jag.

2. From the receiver end and preferably through a bore guide, push the patch through the bore allowing the patch to fall off as it exits the barrel. Repeat with a new wet patch.

3. Soak a Montana X-Treme Nylon Brush in bore solvent and work the brush through the bore approximately 20 times.

4. Repeat steps 1 and 2 with two patches of bore solvent. If fouling is still present, repeat step 3. If copper deposits are still visible, apply a liberal amount of Montana X-Treme Copper Cream to a tight-fitting patch and work back and forth through the bore several times, followed by a wet patch of bore solvent.

5. When satisfied the bore is clean, run two dry patches through the bore.

6. To further protect the bore and reduce fouling and copper buildup, add a small amount of Montana X-Treme Bore Conditioner to a patch and run through the bore two times. Ensure that you do not leave a heavy amount of bore conditioner oil in the barrel.

7. Use Montana X-Treme Bore Solvent to clean actions and fouled surfaces.

8. Use Montana X-Treme Gun Grease as needed on friction parts.

9. Use Montana X-Treme Gun Oil as needed.

Removing Heavy Copper Deposits

1. Soak a suitable-sized patch in Montana X-Treme Copper Killer 50 B.M.G. and mount on a jag.

2. From the receiver end and preferably through a bore guide, push the patch through the bore allowing the patch to fall off as it exits the barrel. Repeat with a new wet patch.

3. Soak a Montana X-Treme Nylon Brush in Copper Killer 50 B.M.G. and work the brush through the bore approximately 20 times.

4. Soak a patch in Copper Killer 50 B.M.G. and run through the bore one time.

5. Apply a liberal amount of Montana X-Treme Copper Cream to a tight-fitting patch and work back and forth through the bore five or six times.

6. Wet a patch with Copper Killer 50 B.M.G. and run through the bore. Repeat this step. If copper is still present, repeat steps 5 and 6 until copper fouling is removed to your satisfaction. For extremely difficult copper deposits, run a wet patch of Copper Killer 50 B.M.G. through the bore (at step 4) and allow to “soak” for 30 minutes before proceeding. Note: Copper Killer 50 B.M.G. will not damage the barrel, and additional “soaking” time is not harmful.

7. When fouling is removed to your satisfaction, run two dry patches through the bore.

8. To further protect against fouling and copper buildup, add a small amount of Montana X-Treme Bore Conditioner Oil to a patch and run through the bore two times. Ensure that you do not leave a heavy amount of bore conditioner oil in the barrel.
