I doubt that copper "between a couple lands" is an issue after one shot. I would be more concerned with copper on top the lands (rifling). Especially if it is on one or two lands in particular. Also know if you are seeing this at the muzzle end , looking in with a light this could be normal in that area.
What bullets are you shooting in it?
What copper cleaners have you used?
