Just as an add on to my reply, and because others have brought it up, do yourself a favor use a bore guide whenever you run a cleaning rod down your barrel.

Break in for me is kinda odd, the only time I really think it helps is with a barrel that shoots pretty good, but fouls quickly and then I get a flyer, I' ve never noticed that it helped my good shooters any though.

As for Solvent, any good copper fouling formula will do, I have been using Birchwood Casey' s " Bore Scrubber" and it seems to be doing fine.
