A fellow needs to do a little more research instead of relying on one man's opinion, many serious BR shooters DO use JB Bore compound, as stated in the following article from 6mmBR/Accurate Shooter, numerous BR shooters and barrel makers use abrasives for cleaning, others won't even use a brush...of any kind, their cleaning techniques vary a great deal from minimal to extreme.
Tim
Yes Tim, many bench rests DO use JB Bore Paste... But they use it to CLEAN their bores. Not to polish them. Its a huge difference. We are speaking about cleaning or not cleaning, as it pertains to barrel break in.
JB is made for cleaning and it contains a very, very fine abrasive suspended in a solvent paste. We all know copper fouling is very hard to remove, Molly is near impossible. JB does a good job on both. It’s mild and makes a quick job of it. It is NOT designed to remove steel from the barrel, it is designed to remove fouling. More specifically, Copper, Lead, Molly and powder residue.
You shouldn’t just find and paste a quote and take it as if it’s 100% gospel. What you end up with is a true enough statement, but one taken out of context. Also, as I stated and Tim, you repeated, some also use NO brushes. Many more bores are ruined by cleaning rods and brushes than every is done by shooting alone. This doesn’t mean don’t clean, it means clean properly!
Don't get me wrong guys, obviously you will do what you want. It's not my barrel you will be working with. I really care and would simply hate for you to take one method as the only way, (I like to call it gospel.) only to later find out something else works better. I try to dispel some of the "misinformation" I in the gun industry. There are truths and facts and then there are opinions. Case in point, I read articles in gun rags all the time, (I'm sure you do too.) where Joe Author prints something you know simply isn't so. Even educated well respected people, who should know, continually publish writings that are FAR from the truths in the real world.
Back on topic, I fully admit that something that works with a fine custom barrel
MAY have no use with a crap barrel, but what if your "crap barrel" turns out to be a good one??? Allowing your barrel to get dirty to see if it likes it that way is fine, but one thing is for absolutely certain eventually it will become too dirty. How do you maintain a just dirty enough point??? What happens as the roughness of that bore is polished out??? What happens when you find one that shoots best squeaky clean??? Absolutes and all the times, are not a common occurrence.
I have a couple Handi’s that actually prefer a clean barrel! These also happen to be some of my most accurate barrels. I have a couple 22 rifles that do well dirty, but my Benelli M90 and Walther OSP target 22 autos, DEFINITELY like it CLEAN! I have a fine old Hamden built, High Standard M101 Olympic 22Short that refuse to group at all if not cleaned every 100 rounds or so. I also have three custom Shilen Barreled bolt rifles. The 6.5/06 shot tiny groups right from the starting gate. It’s clean or nothing for it. Then my Whelen doesn't care about anything, sans copper fouling. Once it gets too much copper, it starts to open its groups. Lastly the 280 started out a excellent shooter, but now that its got a couple hundred rounds thru it, its needing a couple shots thru its bore to group well. So, as you can see, I too have some that like it dirty or at the least dirtier.
Each of you also has his own experiences driving your opinions. If what your doing works for you, no one should change your minds.
Another fact, every year gunsmiths make many $$ “fixing” rifles that simply will no longer shoot good groups. You may be surprised to learn, MANY are simply "fixed by properly and completely cleaning them! The simple fact is sooner or later, Copper, Lead and powder fouling WILL have an adverse effect of accuracy. Anyone who says different simply isn’t being truthful with you or them selves.
As for break in and cleaning, don’t listen to me or anyone else here. At least anyone who is not making a living making gun barrels. Go read what the manufacturers have to say. This is what they do and what they stake there reputations on. All should agree, that these guys know there stuff.
Shilen barrels says:How do I clean my new Shilen barrel?
As with break-in and using coated bullets, you will find many diverse opinions on this subject.
EQUIPMENT: Cleaning Rods: Use a good quality coated cleaning rod with a rotating handle. The rotating handle allows the brush or patch to follow the lands and grooves. A non rotating handle forces the brush bristles to jump over the lands and grooves instead of following them.
BRUSHES: Use a good brass or bronze brush with a looped end. Do not use a brush with a sharp, pointed end.
SOLVENTS:
Every shooting product manufacturer has their own miracle solvent, and most do the job as advertised.
BORE GUIDES: Highly recommended!
PATCHES: Flannel or cotton patches work the best. Either trim or fold your patch to insure that it will fit snugly into the bore, but not so tightly you have to force it. Forcing a patch causes the rod to flex inside the bore of the rifle. If you are using a coated rod, this usually won't hurt anything, but the uncoated stainless steel rods that some shooters use can batter against the inside of the bore and damage rifling.
PROCEDURE: Once again, many different procedures abound. All accomplish basically the same thing. Here's ours: With the bore guide and the brass brush on the cleaning rod, apply the solvent to the brush by dipping it in the bottle or squirting a few drops on the brush. Slide the bore guide up over the brush and insert the bore guide into the chamber with a twisting motion. Push the brush through the barrel until it comes out the end of the muzzle. Now pull the brush back into the chamber guide. This is one "cycle". Make one cycle for each bullet fired, then apply more solvent to the brush and repeat this procedure. Now, fold or cut the patch for a snug, not tight, fit. Push the first patch all the way through the bore and out the muzzle. As you draw the rod back, the patch should fall off. Put on another patch and push it towards the muzzle until you can feel it touch your finger placed over the muzzle. Then draw the patch back to the chamber and push it once more out the end of the muzzle so that it drops off. Repeat this with one more patch and you are finished. If you are through shooting for the day, lightly wet a patch with a light viscosity machine oil to prevent or retard rust. Push this patch through the bore. Let it drop out the muzzle, and you are done.
HART barrels says:What do you recommend for barrel break-in?
We do not believe that a break in procedure is required with our barrels. If you follow our normal cleaning procedure, outlined in this brochure, you should not have any problems with your new rifle. You always want to clean your rifle as often as your course of fire will allow. If you have time to shoot one and clean, that would be fine, but we personally do not feel it is necessary. Please be sure to only use the cleaning solvents listed in our cleaning instructions.

Lilja Precision barrels says:Break-in Procedure
For an effective break-in the barrel should be cleaned after every shot for the first 10-12 rounds or until copper fouling stops. Our procedure is to push a cotton patch that is wet with solvent through the barrel. This will remove much of the powder fouling and wet the inside of the barrel with solvent. Next, wet a bronze brush with solvent and stroke the barrel 5-10 times. Follow this by another wet patch and then one dry patch. Now soak the barrel with a strong copper removing solvent until all of the blue mess is removed from the barrel. The copper fouling will be heavy for a few rounds and then taper off quickly in just one or two shots. Once it has stopped or diminished significantly it is time to start shooting 5 shot groups, cleaning after each one. After 25-30 rounds clean at a normal interval of 10-25 rounds. Your barrel is now broken-in.
Bullberry barrel works says;"What is your recommended method to break-in a barrel?"
This is the most frequently asked question from customers purchasing a new Bullberry barrel. My stock answer is, "With a premium factory lapped barrel in your hands the break-in has already been done." This is a true statement, but we also want you to take care of your new barrel.
I feel strongly that the barrel should apply one of the new synthetic bore treatment products now available, in order to prevent any type of fouling. We now furnish a sample of Eezox™ Premium Gun Care with all new barrels in an effort to save you time, energy, and most importantly, to give you the most accurate firearm possible.
Use Eezox™ to clean your barrel initially and after every shooting session. It's easy--- a couple of wet patches followed by a tight dry patch will usually suffice---no need to overdo it! A gray residue will show on your final patch. Don't work to remove this as it will allow for continued lubrication and treatment. Using Eezox™ will offer the advantages of moly-coated bullets without the danger of moly buildup. Eezox™ is great for properly cleaned older barrels too. Even barrels which have been minorly copper-fouled can be cleaned using very fine steel wool with Eezox™, and will always be a more successful choice than an ammonia based copper solvent as Eezox™ will NOT open the microscopic pores in the barrel metal which allows for worse fouling in the future.
If you take nothing from what I have written, PLEASE understand all barrels are different. We could go back and forth with this adinfonitum. YOU need to try out different things and see what YOUR barrel likes!!
Merry Christmas,
