I don't believe you can condition or season a bore much as a cast iron skillet. What kind of stuff is going to resist the temperature and friction of a shot or more being fired. A lubed bore will affect the poi, however. In my years of match shooting, I always degreased the bore and then fired one blank load, damp wiped, dry wiped and then fired for record, wiping after each subsequent shot. Now that I only hunt with mls, I sight in using two targets, one for the first shot, the second for a dirty loaded second. Clean and repeat. I clean after each session or hunt and coat the bore with RIG. Our old mantra was clean every day for a week, every week for a month and every month for a year. A little obsessive but you don't get rust. When you paid a C note for a barrel in 1965, you took care of it.
