The way I've done it is to use 20 rounds to break in the barrel. For the first 10 shots, after each shot, clean the bore thoroughly with a good copper solvent. For the next ten rounds, clean after every two shots. As you progress, you should notice the bore giving you less resistance as you clean. Supposedly, this will iron out the tool marks and pores in the barrel steel, which would otherwise foul with copper. I know some guys will also do a couple of patches with Flitz at some point during this.
My feeling this is not too difficult to do, and can be completed in about an hour or so at the range, so why not?
