Regarding copper fouling, a new barrel usually will foul much faster and much more than one that has been used for a while. This is due to minute roughness in the bore that scrapes the copper off the bullet passing through. The way to solve the problem is to clean all the copper out, then shoot the gun, then clean out the copper. Each time, you will note that it copper fouls less and takes less time to clean. with most of my rifles, that is about 200 ~ 400 rds.
Unfortunately, you will never get to the point that the bore is cleaner after you shoot than it was before you shoot. :-^ .
