Beneficial fouling can and does improve accuracy in some barrels. While TA is capable of removing all fouling with an additional application, I believe the BAR barrel also benefits from leaving that little bit of carbon in the flaws in the bore as seen in pictures in previous post.

I've mainly noticed it on my factory stainless, blued and/or manganese phosphate barrels. Not so much on my premium lapped SS, chrome lined and/or DCI/melanite type coatings.
I run a patch of one shot then a dry patch through the bore and wipe down the firearm after hunting season, range session, and/or bad weather but will only do a deep cleaning (copper mainly) when accuracy becomes an issue.
I use CLP Collector for long term storage of firearms that only get fired every five years (Grandfathers, Classic and/or Antiques).
