I love this topic because it's never resolved. I figure it can't hurt to do some sort of break in procedure as you only get one chance to do it. However, I was reading a Howa owners manual at work the other day, and it was insistent that their break in procedure was followed. I don't recall it exactly, but it was something like shoot one, clean and repeat for 10 rounds, the 2 shots and clean 10 times, ...etc.

Here's what was interesting....the manual said that their procedure was essential to accuracy because the barrel develops a "memory". Never heard that before. You can read it here:
