cleaning copper out of barrel?

[dwstone1227]

I recently cleaned a handgun with Hoppes #9, my old time favorite. I ran several clothes through until they came out "clean". Then I thought I would try some Butch's Bore Cleaner. I had just bought Butch's so why not give it a try? The first swab using Butch's after Hoppes came out absolutely filthy. I ran several more swabs of Butch's until they came out clean. Then I ran a last swab of Hoppes #9 through and it also came out clean.
After this experience I have become a Butch's fan. It smells terrible. I love the smell of Hoppes #9, but I like having a clean barrel after I'm done cleaning.

What I use is BlueWonder bore gel to remove copper fouling. It works fast cleans quick finish up with an oil soaked patch down team bore,

Another vote for BoreTech Eliminator. Works on copper and powder fouling, doesn't stink to high heaven, doesn't attack the bore. Does a good job.

2 pages and no mention of Barnes CR 10?

I used CR-10 before I found Bore Tech Eliminator. What I liked about CR-10 is that it attacked copper and powder fouling better than Sweets 7.62
What I didnt like about CR or Sweets is the ammonia content

This fellow tested Boretech Eliminator against KG-12 and, so far as I can see, they came out so similar in practical effectiveness as to be indistinguishable.

I can say that Boretech requires no physical effort to speak of. We have an embarrassment of riches when it comes to copper removal these days...but...the real question is whether we are stepping on our own privates in removing it at all.

This fellow makes a case for the necessity of leaving it in our barrels.

He begins to talk about copper at about 3 minutes into the video...

I will say this: I was very happy with the accuracy of a Win. 70 chambered in 280 Rem after working up a load of 52.5 grains of IMR 4350. It was giving me .3 of an inch groups at 100 yards. Being obsessed with ever greater accuracy (like ever sharper knife blades) I determined to improve on .3 groups.

I went off on a quest to get even the shadow of copper residue out of that barrel and I finally did. But to bolster the case for leaving it in, my accuracy did, in fact, fall off.

Now, I did also lighten the trigger (in the abstract that should have helped) and tried various other powders that extremely knowledgeable professional reloaders assured me would benefit everything in my life including my breath.

After all my "improvements" I am going back to leaving the copper in, having a trigger set at 4 lbs, and IMR 4350. I don't care what works for the rest of the world. More power to you, whatever you choose...

Now, if only I could break myself of the passion to get knife blades sharp enough to cut sunlight...

Best way to never have to deal with copper fouling. It really works.
