My opinion is it is far more important to put your first 100 rounds down the tube with ammo that is loaded to less than 1 thou runout! If bullets are starting unevenly in the throat how does one expect to get an even wear pattern on the throat! That's the only so called "break in procedure" I do and have had great results.

Good bullets properly placed always work, but not everyone knows what good bullets are, or can reliably place them in the field
