Proper way to break in a new barrel
 

I just picked up a NEW CVA Accura V2 and am wondering what everyone is using to break in their new steel? I've heard bore butter seasons the barrel. Is "seasoning or break in" required on a bergarra barrel? if so what do you guys do and how many rounds etc???

use 200 to 250 strokes of jb bore paste. for something to protect the bore from rust. save the bore butter for conicals. for bore protection use something like remoil, hoppies 9, rusty duck oil, or any other good gun oil.

you don't need to season an barrel. just need to break it in. if you do use bore butter as an protective. make sure the bore is completely dry. bore butter has some wax in the mix. if you have any moisture in the bore, it will give you an rust patches

Im confused with the wording of your reply. JB paste for protectant or remi oil, etc. also, what is required to "break in" a new barrel?

jb bore paste is an bore polish. a lot of us use it to help break in new barrels or to bring old barrels back to life.

I use remoil as an protective.

tell ya I need an day off, did not see the model.

with the accura, run an cotton ball down the barrel if is snags you need to do some type of polishing or shooting method on it.

"breaking in" a new barrel is not as critical for a ML it is for a CF rilfe. The breaking in is not a seasoning but it is a polishing as Corey states and why the use of JB compound is often used. No matter what the machining process used to put the rifling in the barrel, it leaves minute burrs in the bore. These burrs are what catch the fouling and make a rilfe difficult to clean. And a less than thorough cleaning will cause continued fouling buildup resulting in less accuracy. Therefore, if you remove these burrs early in your purchase you will have a rifle that cleans up easier and accuracy will be maintained.

I think befor you consider using any JB Bore's Paste you better read up on the 5 Step Process Bergara uses to make there ML Barrels. They need No Break in at all, there some of the Best Looking Barrels I have ever seen inside, there so smooth and Mirror Shiny that you wont believe it.
They Load with ease and Clean up Fast and Easy. I have 3 Bergara Barrels and this is just My Opinion on what I have found. If all MLer maufactures made there MLer Barrels the way Bergara does then they put JB's out of Business.

bp, jb still be around. look at all the older muzzleloaders out there that would need a little tlc now and then ;)

I can shoot My ACCURA then just run one swipe of a Nylon Brush down it with Soap and Water, Rince, then run a couple of Patches down it and it's Spotless. I do use Montana Extreme Bore Conditioner in all My Bergara Barrels. I run a Patch with a very small amount of MX down them after a Clean followed by a Dry Patch then Load, and also befor I store them I run a wet Patch of MX down the Barrel, this stuff is wasome. Also My 3 Bergara Barrels are all Stainless Steel.
I could see using JB's with other New MLer Barrels as Im sure there could be Tiny Burrs in the Barrel, but Bergara Barrels are Inspected befor there sent out and go 2 Steps Further in the Making of there Barrels than Most All Mler Barrel Manufactures, Insuring the Inside of there Barrels are like None you've ever seen befor. Any of you who have'nt seen the inside of a Bergara Barrel or Used one then you wont know what Im talking about untill you do.

Corey, I said if ALL MLer Barrel Manufactures Made there MLer Barrels with the 5 Step Process like Bergara does then JB's would be in Trouble. YES I agree JB's is Great Stuff, and will be used for a Long Long Time, but never in any of My Bergara Barrels.
Buy that 45 Cal ACCURA with a SS Bergara Barrel and You'll see what I mean.

saving for it. still going to be a few months. i do have an cabela's visa and an bill me later account. but I have an filling those are going to be used for other things. I won't kill an card on anything big unless I can pay it off fast. learned that the hard way

Don't believe in barrel break in for any rifle. Three of my centerfire rifles got new barrels this year. Those barrels got cleaned and then fired at the range. After the first range session they were cleaned again. Those guns turn in < .75" three shot groups at 100 meters.

The Bergara barrels are very smooth. The cheap CVA non-Bergara barrels are smooth too. TC is famous for sending out rifles with rough barrels: They are accurate but hard to load. i work them over using jeweler's rouge.

Falcon - You're missing the point on breaking in a barrel. The breaking in removes the fine burrs or other imperfections in the bore. Some bore are worse than others. The breaking in does not make a barrel shoot better (immediately). Barrel break in removes the barrel imperfections which can collect and hold fouling. It is the fouling that ruins accuracy. Breaking in allows you to clean the barrel better keeping it shooting good.
Breaking in will not make a lousy barrel shoot good no matter what.

i can undertstand hand lapping a rough barrel or smoothing it out using bore paste or jewelers rouge. i refuse to grasp the concept of ritual barrel break in. Fouling will accumulate in any centerfire rifle barrel, broke in or not. A few of my rifles like the barrel almost totally free of copper fouling. Three of them require some fouling for peak accuracy. The biggest culprit in barrel fouling is monolithic copper bullets.

For years i fired between 15,000 and 30,000 centerfire rifle rounds every year: This year it was about 10,000 rounds. Among the barrels bought new this year is a Shilen barrel in .22 Cheetah MK 1. The bore of that barrel was hand lapped at the factory. It will have a service life of about 700 rounds; any ritual break in would reduce that barrels life. Nothing is gained by "breaking in" a hand lapped or hammer forged barrel; it's smooth as man can make it. Its not going to accumulate fouling at a fast rate unless monolithic copper bullets are used.

i'm a fan of Gale McMillan, a prize winning benchrest shooter and barrel maker. McMillan calls barrel break in a myth. He goes further:

I have never broke in a barrel with any kind of special procedures. I just shoot them and the more I shoot them the better they get and just keep it clean and protected in between shooting them.

I've never seen the point in breaking in barrels either. I've had some accuracy issues with new muzzys, but they were fixed by either free-floating the barrel and/or glass-bedding the action. From what I've seen, the barrel was not the culprit. I own CVA's and a Knight, and none of them required a barrel "breaking in" to shoot well. For example, my Knight shot a 1/2" 3 shot group at 50 yards (I know, not 100) with shots 4,5,and 6 out of a NIB rifle.

Stay away from bore crap...errr Butter.

I'd get some jb bore paste and run only 60 passes, changing the Snug fitting patch every 20 strokes. Leave your breech plug installed and do this all from the muzzle. A note, take the cotton from a Q tip and plug the breech plugs primer hole. I learned this after my first time with jb bore paste. The paste will squeeze into the BP and squirt all over in the frame LOL.

After that you can clean the jb paste out of the barrel with birchwood casey gun scrubber.

After bore is clean, follow up with a light oil like birchwood casey barricade, Rig #2 or any other good brand of oil. Stay away from bore butter style lubes.

I usually shoot mine 10 times with Blackhorn209 and then fully clean it. After that its all shooting and cleaning later on at the end of the day when im finished shooting.

If you're going to be shooting Triple 7, Pyrodex, American pioneer, Swab the bore clean after each shot.

Dang MD, I thought you was a CVA, Bergara Barrel Guy......why the JB's on a Bergara Barrel?? what's so Imperfect about the inside of them? why wear out your Barrel when you dont have to? All My Bergara Barrels are the Smoothest, Easiest Loading Barrels I have ever seen, with a Mirror Finish Inside.

just to remove anything thats in the bore. It also slicks up the bore for a nice smooth feel when reloading on a dirty bore. Its not imperfections but a good way to ensure everything is cleans out of the grooves and you have a nice clean bore to start off with.

OK, I guess we are all entitled to our own opinion and ideas. So its whatever you deceide as to wheter to break in or not. I will continue to do so and be content. You may continue not to do so and also be happy. I know there are other rifle manufacturers who say TO break in the barrel. Custom barrel manufacturers I would assume take more time with their barrels to ensure the bores are virtually burr free. Production manfs on the other hand are a different story.
