Have broken in a few barrels, all of which was told to use a copper removal cleaner for the break in time, I see that BHW suggests a non copper cleaner during break in, can this be explained in some detail please. Many sights recommend to clean copper at all the cleaning times? just want to make sure barrel is broken in properly.

I wondered about that too. Hopefully one of the gurus will chime in.

Not in detail but Master Yoda feels they shoot better with a bit of coper in them. The true poly rifling of a BHW barrel is different than anything I have shot in 50+ years. I can say, from experience, that even after 150+ rounds you will have to look long hard and far to even get any blue on the patch when you do go looking for it. I use Gunslick Foaming Cleaner and it seems to take out everything on all my barrels and I have never gotten more than a tint on a patch form any of these tubes no matter how dirty they were. I suspect if I DANZAC coat my bullets I could use a bore snake and never worry about it again. I'll still clean as usual but I think it will be only a light cleaning as needed. Greg |

must mean that there are minimal pores in the barrel when all the machining is done, and the copper removal is not as necessary, at any point should a copper solvent be used in the life of the barrel??

All you will be after is a copper wash in the bore. Copper buildup is detrimental to accuracy. I personally have yet to have a barrel get copper fouled. These barrels simply don't foul. I do however clean the carbon out about every 50 +- rounds.

What are some good non copper cleaners to use during barrel break-in?

Bore Tech makes the most incredible copper remover out there. Use *any* copper remover as usual then use Bore Tech CU2. You will pull patch after patch of green and blue.
Now for my change of mind. A US military sniping school as stopped removing copper from all their barrels. They noticed that the first few shots after copper removal changed POI significantly until the copper was laid back down. The amount of copper remains constant once it reaches a certain point.
The sniper instructor was showing his personal rifle and said it is still sub .5 MOA with over 3000 rounds through it an no copper removed.
He said they will remove copper when new students come to class with their rifles so everyone starts from the same baseline. Or when the groups start to open up again, maybe after 5000 rounds or so.
In the new DVD from Magpul, The Art of Precision Rifle, this questions is asked. Precision Rifle Expert Todd Hodnett says the same thing. He does NOT remove copper. And he does not have any "cold bore" first shots.
That being said, I don't believe they are using polygonal barrels, so things could be completely different for a poly barrel. But probably not.
I'm using Bore Tech carbon remover for now and leaving all the copper. Groups are consistent after 100 rounds. I don't notice any "cold bore" shots. Groups are consistent.
YMMV and to each his own. Just something different to consider.

Interesting. The difference that we see though is that not all barrels are equally smooth. Some are natural foulers. The BHW bores are ultra-smooth and usually don't show a lot of copper. The bore diameter comes into play in that a 308 bore could have a batch of copper and be OK but the same amount in a 20 or 223 would be excessive,. Also the velocities we shoot are a factor in that the high speed ones tend to plate more. Additionally bullet composition is a factor. A solid Barnes tends to lay down more jacket bullet for bullet than VMAX or BK.
Cleaning every 10 shots for most of us would be excessive but I think that waiting 5,000 rounds might be extreme. One thing that I do know for certain is that most barrels are not going to shoot with top flight accuracy much past 5,000 rounds in the big bores like a 308. There is no 243, 22-250 or 2220 Swift in the world that will reach 10,000 rounds an still be "acceptable" for their purpose IMHO. For a 243 to last 5,000 would take divine intervention.
Cleaning is a personal experience thing. I taught a few M/O's over the years and the amount of shooting needed to "re-plate" was right on about 3 shots given the average bore we dealt with. Plated, as in MOLY or DANZAC, could vary tremendously from gun to gun but most M/O's don't do the fancy stuff.
