You're fortunate to have Calfee's book. That seems to be the bible of .22 rimfire accuracy. I've never read it. Of course you have to get past his unique writing style, which for me is like fingernails on a blackboard, as I recall from reading his stuff in Precision Shooting magazine.
I pretty much do what mauserand9mm cites, following what Lilja recommends on their website. Very light cleaning of the bore, and considerable attention to the leade area. I use a good quality but worn .22 bronze pistol brush on a non-rotating rod in the chamber area, per Lilja, and others. This assumes a decent quality barrel; sewer pipes require a different approach.
I hate leading, and it's always better to prevent it, or at least stay on top of it, than having to get it out of your barrel later.
That assumes that you're not shooting Thunderbolts out of your Vudoo, Cooper, Anschutz, etc., are you? Don't laugh, I've seen it, and more than once.
