-Shoot three 5 shot groups - clean between each group with a proven copper solvent*
-Shoot a 10 shot group - clean with a proven copper solvent*
* We find Bore Tech Eliminator to be an excellent choice.

The problem, for me, is this:
Regardless of all of the hoopla, I'm old-fashioned, opinionated, and too darned used to what's worked for me to change now.
I've been hunting for 37 years. In that time, I've "broken in" seven different hunting rifles. I did this by cleaning the barrel very well prior to my first trip to the range and, then, putting a box of ammunition through the rifle I'm shooting over a long enough period of time so as not to overheat the barrel. I then took it home, called it good, and proceeded to shoot them like any other rifle I hunt with.
Most of my rifles group handloads under an inch at 100 yards. Two or three group around 3/4" of an inch. The best rifle (shooting-wise) that I own is also the least expensive - a Marlin XL-7 in .270 cal. That one will shoot the whiskers off of the left cheek of a gnat at 100 yards...if I can do my part. My worst shooter groups at around 1.25 - 1.5 inches.
So, as with "which is the best rifle for deer?"; "which is the best round for elk?"; "do I really need a magnum?"...herewith, let the arguments begin.
To buttress my old codger beliefs, though, I've attached an 8-round grouping from the Marlin (with a 9th round "proof shot") to go along with what I've said. The three "flyers" in the 8-round group were caused by the muzzle blast of a ported magnum on the next table.
I truly wish the fleas of a thousand camels would descend upon people like that.

PS...Opinions are like armpits. Everyone has them and some of them truly stink. That includes mine. But it is mine and I'll stick with it. And, to borrow a phrase from Ebeneezer Scrooge, in the matter of barrel break in, I say "Bah! Humbug."

1. For the first 10 shots, clean after every shot including the copper remover. Loads of fun.
2. For the next 20 shots, clean after every 3 shots, again with copper remover.
3. For the next 20, clean after every 5.
Then, I never remove the copper again. With my barrel, I use a brush and then two patches and it is sparking clean. My first shot from a clean barrel hits exactly where the next ones do, so I don't have to worry about taking a clean gun hunting.
Both my Remmy 700 and my daughter's stock Savage Axis shoot comfortably under 1 MOA, closer to 0.6 if we do our part. I figure you need to run 50 or more to work up a load, might as well take the time to break it in right.

If the barrel is new I certainly would not run a brush down it, maybe a cloth with a mild solvent but only if it is dirty in the first place.
If your accuracy suffers then try cleaning it but that won't happen for many, many rounds.
