Welcome to the board! /ubbthreads/images/graemlins/laugh.gif
If you do a search on barrel break in, you will find lots of opinions.
30 years ago, nobody even considered such a thing.
10 years ago, it was a must-do thing.
Now, it has fallen out of favor with most precision shooters.
Frequent cleaning for the first 50-100 rounds will not hurt, if done with a good bore guide and a quality, one piece rod.
Cleaning a factory barrel before the first shot, is probably more important than any break in procedure.
