I have found what works best for me is, after hunting season, I thoroughly clean my bore with Hoppes benchrest, then in the spring when I start shooting again I run a few more patches of #9 just to make sure I have a fresh bore, then I use up to 10-12 shots before i consider my gun fouled to where it shoots good groups, for the rest of the season it only gets dry patches to clean the powder residue out (unless I hunt or shoot in the rain) until my post season cleaning. I have not found a reason, other than weather, to scrub, i.e. remove all fouling, from a barrel from over the course of one year unless massive amounts of rounds are fired through the barrel and accuracy has started to fade. Just my opinion.
