Bluing doesn't cause copper fouling, rough bores cause copper fouling.

You have a blued barrel that happens to copper foul.

While it is not the case that correlation is causation, simply stating their nonequivalence omits information about their relationship. -Edward Tufte

Crow hunter, because you offer no calculations and/or data to support the two assumptions in your first sentence, I think your post would fall into what professor Tufte is calling "simply".

Firing the rifle is the cause.

I heard he actually had a date last week.

He was later found with dislocated arms, a broken leg, broken glasses, a dislocated jaw, and 4 broken ribs.

It is theorized his date stood him up.

Chuckle, chuckle, ha ha ha ha!!

I hope the OP got the answer before this thread was derailed. Sorry for my part in it.

rough bores cause copper fouling not hot or cold bluing unless you let the bluing salt stay in the bore and it caused rust and pitting.

+1 Correct answer!

Doesn't blueing increase drag on polished metal surfaces? If so, would this indicate that the surface is rougher when blued than when polished? I believe that blueing is a rust process and not a coating. The surface is affected and this might cause some extra roughness over a surface that is polished. What ever the cause, the copper fouling is easier to see when the bore is blued. I don't remember the plugs coming out of the bore when hot blueing, but it's been a long time. We tried not to blue the bore back then.

I guess you could call rust bluing a rust process. What about the SS barrels with the same copper??

There is a local Smith that blues a lot of barrels. I asked him about plugging the bore, he said don't worry about it a couple of patches with JB and it will be gone. I have two that he blued and it seems he was right.

Seems like all evidence of bluing would be gone quickly with the firing of a few rounds.

That ain't even a choice - Pac-Nor is it hands down. I have more Pac-Nor barrels than any other including Brux, Criterion, Douglas, Hart, Kreiger, Schneider, Shilen, and Pac-Nor is right there among the most accurate. Their installation is good too boot.

Kinda like Chebbys and Ferdges. We like different brands for our own different reasons.

What makes you so sure about THAT? Can you prove it?😜

I wonder if good ole Dyna Bore Coat would help that fouling problem?

I've had both Pacnor and Douglas and they both shot very good, I doubt you would be able to tell much difference in accuracy between them.

Pacnor bores are lapped and Douglas bores are not lapped, which is a difference. Douglas fouled a lot, as much as factory barrels, and Pacnor very little.

Pacnor installed mine and did a very nice matte finish blue, a local smith blued and installed my Douglas.

I've had Douglas do a couple barrel installs for me a fast twist 243 and fast twist 204. Both guns were done in bead blasted stainless steel and the final cost with shipping was like $650. On their installls they use the xx air gauged barrels so they should be good. Both of the guns have been extremely accurate and I have had no problems. I have shot them both to foul cleaned them and didn't have a problem at all after that.
