Your question is going to open up a hornets nest , lol.
This question was asked recently and the majority said they cleaned it when they bought and then go out and shoot the crap out of it.
I break-in all my barrels and its been said that they will clean up easier, mine seem to, but I have no guns that have not been broke in, so I way to compare it.
The best 3 shot group for my .204 to date is .101 at 100yds, the 22-250, .118 and my 25-06 is at .156. Does it help? I don't know.
Folks will tell you its a waste of time, I say if you want to do it knock yourself out, I doubt it will hurt anything.
