Plated or copper wash bullets will smooth out the roughness - but - it's a PITA in the meantime.
I've been lapping all my S&W barrels on new guns made in the last 15/20 years just as a matter of course.
I believe the way they are now made leaves the bores rough.
Since the vast majority of shooters are going to shoot jacketed rounds, I don't believe S&W will change things or even admit there's an issue.
I use Pepsodent toothpaste for a compound.
It's just abrasive enough to polish -but - not abrasive enough to do any real metal removal.
I used that on all three of the barrels I have for my 22/s.
