Be careful with the Chore Boy method. I've used it on occasion with heavy lead fouling. I had a .44 magnum SBH that was out of spec between the chamber and bore diameter; could never find a load that didn't lead terribly after much experimentation and it seemed Chore Boy was the only trick that would work.
However, if you wrap too much of the copper padding around your bore brush, it is possible that it will become too tight in your bore and thus too abrasive. I recently scratched the bore of one of my stainless revolvers recently with this - down toward the muzzle. Fortunately it's not enough to inhibit accuracy, but I will never be risking Chore Boy again.
Lead is all I shoot as well. As long as you're using the appropriate bullet, you shouldn't have any real problems. To add to what Drail posted, keep in mind that it is possible to have too hard of a bullet for your application. The harder a bullet is, the more force needed to cause it to obturate (seal the bore to prevent gases escaping). I've experienced heavy revolver leading which I would attribute to using too hard of a bullet with too light of a load - such that the bullet is not obturating properly and gases are escaping past the bullet as it makes its way through the forcing cone. These gases the solder the lead to the bore/forcing cone. I've corrected loads like this using same bullet size/shape/weight - only moving to a softer lead. On the other hand, I've used those same hard bullets in heavier loads and experienced no leading.
All in all, the only revolver I've experience REAL leading problems in was that damned SBH. I've never had real problems since then. Keep in mind also that lead is actually easier on the bore than jacketed ammunition, and in all practicality should actually prolong bore life.
Do a little reading up on shooting lead and then dive in. You won't be disappointed.
