Removing Lettering from an Octagon Barrel

[MtnMike2]

How easy is it to remove the lettering from an octagon barrel? I saw where one guy used a draw file technique to remove lettering, but that seems like it would take the metal down farther in one place than others?
I'm building a Lyman Great Plains Rifle and would like to remove at least some of the lettering on the barrel, like where it says to read the manual...
Does anyone out there have any experience or suggestions?

Thanks,
Mike
