Do's and Don'ts of Barrel Cleaning
Do's:

Use a good coated rod
Use a bore guide
Clean from chamber end (whenever possible)
Use a bronze bristle brush
Follow recommended break-in procedures (listed below)


Don'ts:

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, the loss of accuracy can be linked to a dirty or fouled barrel approximately 98% of the time!

Barrel Break-In and Cleaning Techniques

Thanks for purchasing a barrel from us!

For best results, of course, it is necessary to 'season' it and use proper cleaning equipment. 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. You will need a good bore solvent, like KG 3, Shooters Choice or CR-10 to loosen the fouling, followed by a scrubbing with Holland's Witches Brew or KG 2. After cleaning, nullify the solvents with rubbing alcohol and patch dry. Finish with Tetra Gun Oil, KG 4 or Holland's Bbl Break-in Fluid. Never shoot a dry bore as this will greatly promote copper fouling.

Chris recommends:
Shoot one, clean, for first ten rounds; shoot three, clean, for next thirty rounds; shoot five, clean, while working up load. Allow bbl to cool to the touch before testing a new load to avoid unnecessary throat erosion.

Sweets 7.62 should scrub that copper out though, just make sure you neutralize it before putting it away.
Hope this is reading is of some use to you.

maybe the hoppes isn't getting all the copper out. try wipeout or wipeout liquid and use the accelerator too. speeds up the job.
 
I purchased a rifle recently that fouled badly after only firing a few dozen rounds. After using aggressive copper solvent type cleaners to get the barrel squeaky clean, I then proceeded to polish the bore with a non embedding bore paste such as Flitz. I did this over several range/cleaning sessions. Then one day the barrel stopped fouling. I can shoot 75 rounds of high velocity 22 cal hand loads with only very minor fouling. The barrels cleans up in mins vs days. We'll see how it does with a higher round count between cleanings.

Edit: There are far better products than Hoppes for copper removal. As suggested by another member, consider other options.
 
Thanks for the advice Rob, chappy, hend238, and Robmcleod82. I will try stronger products, but I still don't understand why a brand new Super Match Grade barrel is fowling so badly at low velocity
 
Go back to the importing dealer and see if they can contact Pac Nor for a remedy.

Their top line barrels should be properly lapped so this shouldn't be a big deal.

Is this a prefit?

Is there copper visible near the muzzle?

Does it affect your accuracy?

Many barrels shoot superbly but when cleaned, show a blue. Does it matter? up to you but as long as you get fair duty cycle before needing to clean and the performance is good, I would just leave it alone.

As was already mentioned, some new barrels just need the internal rough spots or throat to get worn off. You can speed this up with a lapping using JB Bore Brite BUT talk to the manf first as some will not warranty once end user intervention has occured.

Copper fouling is of little importance if it doesn't affect your accuracy. But if you want to get copper out of a bore.. use a strong ammonia solvent with Barnes CR10 one of the best..... life is way too short to use Wipeout if heavy lifting is needed.

The accuracy is good 125 g. Nosler Partition three shots 3/8" to 3/4" @ 100 yds 2650 to 2700 fps with different powders. I own three other rifles with Douglas Air Gage barrels and never had this issue with copper fowling.
Thanks Tick
 
Try some kg12 works great on copper only thing is it doesnt show the blue color that most copper solvents do if you need to see that.
