Accuracy with a fouled barrel

There is an interesting lubricant called "Copaslip" and others that use copper particles suspended in a "grease". They are designed to provide slip under enormous pressures. Like graphite and molly types, copper has this ability to slip on itself. I wonder if this is what is happening with some of these rifles that shoot better fouled? Perhaps the extra slip is contributing to a timing slove for the bullet traveling down the barrel? I'm also wondering if having that copper in there helps prevent wear?

As long as the bore is cleaned of carbon and that it's protected from moisture, would there be any adverse effects to never brushing that copper out?

The other thing is that the copper would be constantly renewed. I've looked at copper in my rifle bores and I can say that it looks pretty darn smooth laying in there, actually smoother than the steel machining.

fouling

I think there are rifles/barrels, that are destined to be "foulers" and will need steady attention. And I believe there are barrels that do quite well with light cleaning.

Much of it likely has to do with the quality of the barrel, how good the tooling was when the barrel was made. I have a Wally World Rem 700 ADL .270 that I bought 15+ years ago, at the mega store price point, that is a chronic fouler. After 20 or so rounds (box of shells) you can see copper fouling at the muzzle, and accuracy has begun to deteriorate. Patches show much green when cleaned later. I keep it because it has a gorgeous trigger, and will shoot sub MOA 3 shot groups for those first 20 rds or so, before it starts to go. I also killed the first buck I ever had mounted with it, so I've got some sentimental ties to the rifle as well.

Liberal use of JB has helped it SOME, but the greatest break has been the foaming cleaners, much less work.

Conversely, my F-T/R Savage .308 monster, w/ factory heavy bbl, goes a full match , say 75 rds+ plus in a day, and shoots tighter than I can hold.
 
I take Copper jacket bullets up to 2800 fps, to reduce Copper fouling.
I take Copper jacket bullets with Moly coating up to 3500 fps, to reduce Copper fouling.

The 204 is just way too fast for my speed limits.


Buy a used Ruger #1 and shoot it.
Then clean Copper for 3 hours.
Then shoot it again... the groups are 1/3 the size they were.
No wonder you got that gun so cheap.
