The most important thing about breaking in a barrel is cleaning the rifle right. To do so, requires the right cleaning equipment. More harm than good can come from cleaning a barrel with the wrong equipment. All cleaning will be done from the chamber end period. Nothing will go down the muzzle end. Patches will be removed at the muzzle end and NOT pulled back through for any reason.


A list of equipment needed:


Dewey Cleaning rod, Nylon coated.

Dewey Cleaning Jag, (Push through type, not the loop type)

Bronze Cleaning Brushes

100% Cotton Flannel Patches (Round or square)

Bore Guide

Sweets 7.62 Copper Solvent

Kroil or Hoppies #9 (either/or is fine)

Bolt Locking Lug Grease

Chamber Swab


With a new rifle, it is dirty from the factory. The first thing in order is a good cleaning.
 
Cleaning procedure:


Step 1


Unload the rifle and place it securely in a cleaning rack.

Remove the bolt.

Install the bore guide.

Install the bronze brush on the rod.

Soak the brush with Hoppies #9 or Kroil.

Make 20 passes back and forth in the barrel.

Remove your bronze brush and install the patch Jag.

Wipe your Cleaning Rod with a Clean cloth.


Step 2


Saturate a patch with Kroil or Hoppies #9 and pass it down the bore. DO NOT pull it back through. Let the patch fall off at the muzzle end.


Repeat step 2 until powder fouling is removed Usually 3 patches. Wipe your cleaning rod before each patch.


Step 3

Put a generous amount of Sweets 7.62 on a patch and make a pass down the barrel. Allow the patch to fall off. Wipe off your cleaning Rod.


Follow immediately with a second patch with the same setup.


Wait 5 minutes.
*Warning* Do not let Sweets stay in the barrel for over 5 minutes, pitting COULD result.

Again put a generous amount of sweets on a patch and make a pass down the barrel. Examine the patch at the muzzle end. Bluish/Green color on the patch signifies there is copper in the barrel.


Repeat step 3 until patches come out without the Blue/Green color.


You may then run 2 dry patches down the bore.

If long term storage is required, after the bore is dry, run a patch down the barrel with your favorite rust preventative.

Remember, if you go this route, make sure you DRY swab the bore before shooting again. I personally use Hoppies #9 if I am putting the rifle away for a month or so.

If between range sessions, I leave the bore dry.

Remove the rod guide, dry the chamber with a swab,
wipe off your bolt, clean the boltface, and lube the locking lugs with a small amount of bolt grease.


Reinstall bolt.


BARREL BREAK IN


Step A…….. (Typically 6 to 10 Rounds)


With a clean barrel, Fire one round.


Clean in the 3 step procedure as above. *Do not let Sweets remain in the bore for over 5 minutes. If you have to leave your rifle, Run a patch saturated with Hoppies #9 through the bore and let it set. Hoppies is a very mild cleaner and will hot harm your barrel if allowed to remain in the barrel for an extended amount of time (Months).


Repeat STEP A until you see a significant reduction in patches used to remove the Blue/ Green color.

You will probably start out using 6 to 8 Sweets saturated patches to remove color. When you get to the point you are using 2 patches to remove color, you are ready for the next step.


Step B ……….(Typically 5, 3 Round groups)


With a clean barrel, Fire 3 rounds.


Clean in the 3 step procedure as above

Once it takes only 2 patches to remove color, proceed to step C


Step C …………(Typically 3, 5 Round groups)


With a clean barrel, fire 5 rounds.

Clean in the 3 step procedure as above.

Proceed to Step D when you fire 15 rounds total.

You can go to 20 if you feel the rifle needs it.


Step D ………..(20 Rounds)


With a clean barrel, Fire 10 Rounds.


Clean in the 3 step procedure as above.

You are done when all 20 rounds are expended.


Now, Cleaning your rifle vs. rounds down range is up to you and your rifle. I always recommending cleaning after 100 rounds expended, after a match shoot, or after shooting a high rate of fire were barrel temperature was extreme (too hot to touch).


I have noticed that MOST of my rifles shoot best with a Minimum of 30 rounds down range before group shooting. This is not the case with all rifles. Some shoot best with a totally clean barrel.

For tactical rifles, or rifles that may be called to action at a moments notice, I always recommend after cleaning, fire at least 1 fouling shot before putting your rifle away. Then, when you put your rifle into service, you are ready for your cold bore shot.
