Any imperfections will stay in the barrell without proper break in.
Remove the copper and shoot again, your basically lapping the barrel by doing that, if you dont remover the copper, your not lapping. Plus it reduces fouling.
Thats the way i undertand break in.

I am not here to argue cause I really dont know the truth on this, but yes everything I have read is 100 or so rounds through a barrell before its broken in, but you have to get the copper out for it to work. or handlap it right off the bat.
It seems that if a cleaning rod can ruin a barrel that easy, 100 bullets down it would lap it.
What cleaning rods do you reccomend, a brass or coated one, seems brass wouldnt harm a barrell.

Sometimes it works sometimes it doesn't. For the most part RR is correct. A badly machined barrel will never break in and will foul worse than normal barrel forever.
The procedure proscribed with a new gun is a waste of time. The procedure is like knife sharpening. Every knife is different and every edge is different. Going thru the same procedure for every knife without understanding what is happening will leave you disappointed. But if you stop and realize what is happening and go to the next stage of honing when appropiate, then you come out with a sharp knife. But like knife sharpening, you can make a turd barrel into a match barrel by shooting and cleaning.
These results are based off of dozens of rifles broke in. And use of a hawkeye bore scope.
I like breakin to a point. During the first 100 or so rounds of a barrel, I notice velocity std dev. are huge. Sometimes break in settles a barrel down. You are doing the same thing shooting and cleaning over your several shooting sessions without breakin.
If you clean and shoot one round, and clean and shoot, and you always get copper fouling, and it never lessens, chances are, it never will. Waste of time. Breakin can only do minor smoothing.
But if say you shoot and clean and copper goes down to nothing after 5 cycles of clean and shoot, then something is working. Move to 3-5 shots then clean. If you see fouling go down considerable each cycle, move to 10 shots.
I agree you can accomplish same thing by shooting 10-30 rounds, whatever you ususally shoot at a session. And in the first 200 rounds, its the same thing and good as its going to get.

Without a proper rod guide ridge runner is correct, perhaps correct even with a rod guide in some cases

Buy the gun, clean the gun before shooting and then shoot a couple of rounds through it and clean again. Break in is then about as done as it's going to get. That's how I have always done it anyways.
