Cant seem to get the copper out of new Krieger barrel

TOPOsniper said:
I have a new 308 precision rifle with a Krieger barrel built at GAP. Last weekend I went to follow the Krieger/GAP break-in procedures and only got to the fourth round.

Using Shooters Choice Copper remover I followed the directions exactly but after the fourth round cleaning, I checked the bore using the q-tip method JeffVN showed me recently and I was shocked at how much copper there still was in the barrel.

Since then I have stepped through another 8 cycles of multiple wet, brush, wet, dry patches, check. Still has copper.

I went and bought a bottle of Butch's Bore Shine and did 2 cleaning cycles today and although cleaner, there is still copper in the bore I can see at the muzzle.

Should I expect to see a completely copper free bore on a new barrel? I do not know how many rounds GAP put through it, but I am a bit puzzled.

KG12 inbound to try next.

That doesn't sound typical for a Krieger......Call Andrew Krieger.

I have lapped many a barrel during production and that is with some very fine lapping compound and wool and looked at thousands after. If you have to put 500 on the barrel to get the tooling marks out something is wrong.

Never said I had any tool marks . Just
Something I have done for years . Worked back then and still does today . Larry
 
Someone I don't much care for commented on this very thing earlier.

Doesn't matter if I like him or not, he's absolutely correct on this.

Nor does the age of this thread matter on this particular point.
 
take a soaked patch of shooter choice or sweets (ammonia). take another tight fitting patch and soak with hydrogen peroxide. put the patch VERY slowly down the bore. a bunch of fiz will come out first. attached to the patch will be thin strips of copper. repeat as necessary. do not leave the ammonia in the bore!!! once the copper is gone--I have never had to repeat more than twice, run a patch of hoppes down the bore followed up with a dry patch.

All I am saying is if lapping processes and tooling are correct should not be any need for 500 laps of anything after its made. There is such a thing as to polished of a finish. If it works for you then by all means do it.

For years I worked with guns that
Shot solid copper bullets and if you didn't do it . Ten rounds and you had spend hours removeng copper. Majority of the problem was in the chambers . It's hard to send a gun that price was $40,000 plus back . JB and many strokes sure helped . Larry
 
I've tried Barnes CR 10, M Pro 7, Butch's Bore shine and Wipeout, although I can't find the "accelerator" in any of my local stores. I still have some carbon and copper in the first 2" of my Bore. Has anybody tried straight household ammonia? Maybe I'll have to do 500 strokes?:eek: I'm starting to hate this borescope.:mad:
On another note: Cabela's, of all the places I looked, had the fewest choices of Bore cleaners!:mad::mad::mad:

Barrelmakers love borescopes. They sell a lot of barrels for them.

Try Bore Tech Cu+2 Copper Remover. It works much better for me than Wipeout.
 
I have a few Kriegers, never a problem with copper fouling. What type of brush are you using. If bronze that's the problem.

Stay away from JB, I ruined a barrel with it by using it to much. The pumice is not kind.

I now use Sweets with only a patch and it cleans up pretty quickly. One patch and that usually does it. Do not leave this stuff in your barrel it will ruin it if not cleaned out. I generally use Hoppes after the sweets followed by an oil patch.
 
Ive tried several copper cleaners including Butchs and Montana Extreme. When the going gets tough I get out the KG 12! It is the only thing that will clean my heavy fouling Weatherby Vanguard in 240 Wby. This thing shows visible copper after 3 shots and was litterally impossible to clean until I tried KG 12.

Barns CR 10 copper solvent removed it . Many of strokes with JB made it to where you could regulate the barrels

Man that gun slick really works for me I know a lot of people says it doesn't but blue will drip out fast. And from working on some snub nose pistols becouse I don't have a borescope it takes copper out like crazy...

Makes cleaning pistols so fast it's just a dream.. But I know there's some awsome copper removers out there... But the foam does no damage that I can see compared to some strong copper removers... I have tryed some things people love and just didn't get the results they did.. But what ever works best for anyone is the best...
