New rifle - brake in needed or a myth worth ignoring???

I will just clean the bore out of the box and go sight the rifle in, fire 20 rounds or so, then take it home and clean it. After that I will clean the bore when accuracy goes south, some rifles that takes 500-600 rounds or more

That's what I was going to say, I have had a couple of very accurate rifles that after I removed all the copper fouling and REALLY cleaned them were less accurate until they became fouled again.
 
It does seem that barrels clean out easier and quicker after a “break in” few shots clean etc

I do it with my new guns. If nothing else it gives my other rifles time too cool down between groups :)
 
Barrel break in is nothing more than hocus-pocus. A feel good ritual performed by the individual that provides no more benefit other than self satisfaction.

I always give a new rifle a quick cleaning before I fire it just in case there is anything in there left over from manufacturing. Then I fire just enough rounds to get me zeroed in. Give it another quick cleaning and then I just go shoot the thing. Subsequent cleanings don't happen unless I think accuracy isn't up to par (sometimes up to 200 rounds or more). I hate a clean unfouled barrel as they seldom shoot good. I find it usually takes around a box of ammo after a cleaning to get it shooting good again.

I think it's more important not to overheat a new barrel during the first few outings. All this shoot a couple then clean then shoot a couple then clean then repeat and repeat accomplishes nothing more than give you something to do.

Just my opinion.

I agree

Breaking In the barrel……

The age old question, “Breaking in the New Barrel”. Opinions vary a lot here, and this is a very subjective topic as well. For the most part, the only thing you are breaking in, is the throat area of the barrel. The nicer the finish that the finish reamer or throating reamer leaves, the faster the throat will polish/break in. A rough throat can take longer to break in and also cause copper fouling. Some shooters think it’s the barrel has a problem but it could be from when it was chambered.

Shoot one round and clean for the first two rounds individually. Look to see what the barrel is telling you. If I’m getting little to no copper out of it, I sit down and shoot the gun. Say 4 – 5 round groups and then clean. If the barrel cleans easily and shoots well, we consider it done.

If the barrel shows some copper and or is taking a little longer to clean after the first two, shoot a group of 3 rounds and clean. Then a group of 5 and clean.

After you shoot the 3rd group and 5th group, watch how long it takes to clean. Also notice your group sizes. If the group sizes are good and the cleaning is getting easier or is staying the same, then shoot 4 – 5 round groups.

If fouling appears to be heavy and taking a while to clean, notice your group sizes. If groups sizes are good and not going sour, you don’t have a fouling problem. Some barrels will clean easier than others. Some barrels may take a little longer to break in. Remember that throat. Fouling can start all the way from here. We have noticed sometimes that even up to approximately 100 rounds, a barrel can show signs of a lot of copper, but it still shoots really well and then for no apparent reason, you will notice little to no copper and or it will start to clean easier.
 
Buy box of ammo, and clean bore before shooting.

Go to range, bore sight, and fire first shot at 25 yards, then clean.

Adjust scope, fire two more shots, then clean. By now you should be zeroed at 25 yards.

Three shots at 100 yards, then clean.

Adjust scope to preferred point of impact at 100, shoot four shots to confirm poi, then clean.

Fire five more shots at 300 yards to determine drop, then clean.

You are now sighted in, know the trajectory of the load, and have five left in the box to go huntin'. ;)

John Krieger, probably the greatest barrel maker/guru of our time, calls it BS. I'll go with that.


There's a lot of reasons why various manufacturers say to do it, that has nothing to do with making the gun more accurate. One of the key ones is that it gives them a "get out of warranty work free" card.

Well there you go.
You have a custom barrel and where provided with appropriate details on how to care for your new barrel.
I doubt a factory stock average rifle will be up to the challenge yours is .
Routine cleaning and care for a general duty firearm is all that is needed .
What do the men and women in the Military do when they are training?
They dont all get a brand spanking new gun every time there is an intake into the service or do they?

I only every tried it once, with a 7mm mag....the shoot 1 clean, shoot 2 clean, etc, and noticed no difference at all vs my normal "routine". Still takes 50+ rounds to smooth the bore out.
The most noticeable copper fouler I have, is a Zastava Stainless 7x64. After 3 boxes (60 rounds) and my Gunzilla/Wipeout treatment after each box, it no longer copper fouls at all.
 
myth imo.

Do typical disassembly/clean & lube upon purchase, shoot & zero.

Clean as normal after session .... stand on a hilltop and yell "Wolverines" !!!

Break-in complete.



Now if I were some hardcore F-Class guy or the like I might be a little more superstitious.

Ah I been doing it backwards. I always started with WOLVERINES!!
 
The Kreiger video is interesting...some companies (I believe Diemaco is one) hammer forge their barrels AND chambers at the same time...this eliminates (significantly reduces) the reamer marks perpendicular to the bore that Kreiger identifies as the major cause of copper fouling. I believe that Steyr does the same on their SSG barrels as they do not advise break in for a new barrel and suggest only a 'silk noil (whatever that is!) or cotton wool and barrel oil' for cleaning.
 
I have custom barrel now (I know not much to draw from) my shillen barrel never did have a spec of cooper in it. First day after install went and shot it for hours. Took it home and put in some wipeout and there was nothing. 800 rounds later still no copper.

I have tried to do the proper "break in" and after half an hour I said F this and shot the hell out of the gun the rest of the day. Shot that gun a lot in the 4 years I had it and always shot great and very minimal to no copper at all.

Best way I found to break in a new barrel

Perhaps the break-in matters and makes a diference to the paper puncher shooters, but for the average hunter does it realy make a diference? I doubt it.
For me on a new gun I clean it well before shooting the first round, and pay particular attention to the chamber. I expect the new gun has some sort of preserving oil or grease from the factory, and wether it does or not I clean it as if it does. { I do the same with a used gun also }
That out of the way I shoot it , and sight it in, and then take it home, give it a good soaking with G96, and let it sit 10 minutes before running a brush and patches thru it and finish up with a final G96 wet patch .

I never shoot enough to get a barrel hot , when it feels warm it sits for a bit with the action open , and pointed up to let it cool to the touch. This has worked good for over 40 years.

My interest is for a hunting rifle that shoots good at practical ranges, not at something in the next county. sighting 3" high at 100 YDS works for me with all calibers, hold center of ribs , and don't worry about Kentucky elevation , because if this sighting is going to shoot to low it's to far in the first place and I let it walk or get closer. Know the limits of the gun and yourself .
I only load Nosler Partitions, and at the price they cost I am not going to blast hundreds a day into a target.

Yep!

Not so much break in, but I've had more than a couple rifles that shot like crap until well past the 100 round mark, then factory loads I had previously used all of a sudden tightened up to sub MOA

I know guys that 100 rounds is 20 years of shooting for them...
I was gonna say the same thing . My good ol 22 rifles was jamming quite a bit with the Winchester white box when new , now after 1000+ rounds even when dirty it shoots np
 
Ted, I made a shot with the old 9.3x62 I got from you, about 200 yards on a nice WT doe. The 286 partition might have been just enough gun for the job. Blood trail was about 18 inches.
