That was one of the things I really like about the maintenance on the .22 rimfires, you can leave the bores alone for awhile, not like a 30-06 though. On my .17 HMR, because it is a jacketed round, I clean the bore from the action every other visit to the range, or if I plan to leave the rifle for a few months to protect it from moisture. With the cost of ammo going up, I don't plan to shoot my .17 HMR as much as I did 4 years ago.
I am starting to feel like a European with me acquiring more and more .22 LR guns, and less centerfires.
