How do you "break in" a standard factory button rifled barrel, will a bore brush and copper solvent make the button rifled bore below smoother?
Below, the throat.
Below two inches from the muzzle.
Watch the video below on a factory barrel and a custom made barrel, the video should answer your question

Shoot your rifle and then use some foam bore cleaner to remove the copper after each trip to the range is the best way to remove the copper in the bottom valleys of the button rifling without undue brushing.
