It is very hard to lap a barrel once it has been installed without belling it at one end or the other or both.
Clean the rifle when accuracy falls off and follow your cleaning with some JB paste per their instructions. It may take a bit of time but you will smooth the barrel out.
If you are indeed getting sub moa groups, I certainly wouldn't do anything that was too radical to smooth the bore.
