I pretty much had the exact opposite outcome as you. I don't know what type of residue you are getting because the bullets are not moly or teflon coated. They are impregnated with a grit type substance to basically sand away at the rifling in your barrel to smooth it out.
I loaded my bullets with CFE 223, it has a copper erasing ability, but is very sooty. I cleaned my barrel between 10 round sets with Hoppes to remove the carbon, followed by Sweets to remove most of the copper. Then I followed that up using Kroil and JB bore paste mixed together to make a thin paste on a cotton patch. I actually had very little to almost no copper build up in the barrel. The most build up was towards the muzzle end of the barrel .
After the last set of ten were shot I took it home and super cleaned it with the Kroil and JB paste, then sent the barrel out to be Nitrided. After getting it back I had to put at least 150 rounds through it to get it to group as well as it did before. It did not start shooting .5 to .75 groups again until some copper actually started to build in the barrel. And when I say started to build it is still almost non existent, just a few narrow streaks down the edge of the rifling in a couple spots.
This barrel is so smooth inside when you send patches down it it squeaks, so I guess you could say it's squeaky clean. It is also very easy to clean. You know you have a smooth clean bore when they squeak when patched. And it still does not build much copper, and I will not be removing what is in their now as some barrels need some in them to shoot well.

If you can not see the tyranny of having a gun ban enforced by men with guns... Then you fail to understand why the second amendment was written in the first place.
