Noveske Barrel Break-In (Stainless Steel)

[SkiDevil]

I was checking-out the Noveske Website and noticed a new document posted on the site regarding the Cleaning and Break-In of their stainless steel barreled firearms.


BARREL BREAK-IN AND CLEANING TECHNIQUES

Break-in

It is necessary to clean your barrel well using proper cleaning equipment prior to use of the barrel. We have not found any benefits when using an
extended break-in procedure.

Cleaning Supplies & Techniques
We like the Dewey coated rods, a good bore guide, copper/bronze brushes and cotton flannel patches, the appropriate size to keep that jag and rod
in the middle of the bore. When cleaning, the brush or jag should only travel through the barrel from the breech to the muzzle, the same as the
path of the bullet. Do not ever pull a brush or jag back through the crown of the barrel. You will need a good carbon solvent, like KG 1. Shooters
Choice or CR-10 will chemically loosen the copper fouling, but KG 2 is found to remove the copper without the use of chemical solvents which
may attack barrel steel. After cleaning with chemical solvents, neutralize the solvents with denatured alcohol or oil and patch dry. If using KG 2
or any other micro abrasive product, use KG 3 solvent to flush out the bore, spraying from the breech with muzzle end down. Always finish with
Tetra Gun Oil or KG 4. Never shoot a dry bore (chemically stripped) as this will greatly promote copper fouling. Clean
the chamber with a cloth chamber mop, not a GI chamber brush.

SPECIAL NOTE FOR POLYGONAL BARRELS:
Polygonal barrels will be marked with the twist rate followed by a capital "P,” for example, 7P, 8P, and so on. Polygonal rifling does not have the
steep sides to the lands as a standard barrel does, therefore the cleaning brush may not track with the twist of the rifling. Barrels marked 7PT will
be easier to clean than 7P. 7PT Rifling is an improvement which aides in the brush tracking with the rifling. The cleaner must install the brush to
the rod tightly; holding the rod between the fingers using both hands. Push the rod in while twisting it to the right, (clockwise). You will feel the
rod twist. Be sure not to let the brush skip over the lands. Once you push the brush through, remove the brush from the cleaning rod. Pull the
cleaning rod out of the barrel and repeat the process. Do not pull the brush back through the barrel.

Do’s and Don'ts of Barrel Cleaning

Do:
Use a good coated rod
Use a bore guide
Clean from chamber end
Use a phosphorous bronze bristle brush
Follow recommended break-in procedures (listed above)

Do Not:
Do not pull the brush back through the crown
Use a stainless bore brush
Leave strong ammonia cleaning products in your bore for extended periods of time
Shoot your barrel hot enough to brand cattle!
In our experience, a loss of accuracy can be linked to a dirty or fouled barrel. Barrel life and accuracy is dependent on how the
barrel is used. The barrel may be damaged (shortened barrel life and/or accuracy degradation) from excessive heat caused by a
high rate of fire. We are not responsible for barrels damaged by operator abuse.

Along time ago Gale McMillan said the same thing yet not many believed him.

Along time ago Gale McMillan said the same thing yet not many believed him.

Many still don't, otherwise I would not still get told how I should be breaking in my rifles by some shmuck at the range that thinks I care what he thinks

My favorite part of the Noveske break in doc is this

"(Do Not) Shoot your barrel hot enough to brand cattle!"

[Falar]

I got that as a letter with my Noveske barrel a year and a half ago. I took their advice and didn't break it in, and never will break in a barrel in the future.

i just got done posting "i dont even break in my stainless barrels" in another thread, and then saw this one.. weird.

taking the time to break in a stainless barrel isn't going to hurt anything, but there's no conclusive evidence that there's enough difference to make any difference at all.

i did, once, break in a stainless 16" Oly barrel, about 8 or 9 years ago.. ate up my whole damn day, and i never did ANYTHING even remotely close to precision shooting with that build. total waste of time and ammo.

Along time ago Gale McMillan said the same thing yet not many believed him.

Derek Martin also said in his book to just clean and shoot and not to fart around with the many complex break-in schemes.

[Surf]

I have also said the same thing about "break in" for many years. I have done rigid "break ins" and just shoot the damn thing. I have never been able to see a difference in results that I could quantify.

But then again who am I?

FACT: Even the finest double-hand-lapped, stainless steel match-grade barrel is going to have tooling (reamer) marks, running perpendicular to the direction of bullet travel, remaining on the leade when it is new. These reamer marks are not unlike “the teeth on a very fine file.”

The bore-scope view below shows these reamer marks on the leade of a new, unfired Krieger stainless steel match-grade barrel.







The following pic shows the same barrel as above, after having a 20 round break-in procedure performed on it; there’s nary a reamer mark to be found on the leade.









The next pic shows a bore-scope view of a stainless steel Noveske Afghan barrel (that did not have a break-in procedure performed on it) after firing 150 rounds. While not nearly as pronounced as before the first shot was fired, some of the reamer marks are still clearly evident on the leade after firing 150 rounds.
