First off this should be posted in either the GUNS or FIREARMS REVIEW forums.
But, in response, I really don't know why you didn't include how far to shoot with a new barrel in your poll.
I have said it before and I'm saying it again. THE MOST IMPORTANT thing to breaking in a new barrel is to NOT SHOOT TOO FAR UNTIL IT IS ADEQUATELY BROKEN IN (no matter how you choose to breal it in).
Rule of thumb..........
1st 20 shots or so - no further than 25-40 yards.
Then after cleaning, next 20 shots or so - no further than 50-75 yards.
Another cleaning and then the next shots - go out to like 125-150 yards.
Then clean again and you're good to go.
If you just go out and start shooting 200 yards, you will suffer what is called
stretching.
I know those who haven't done thisor heard of itmight question the logic behind it, but those who do practice it are usually firm believers.
