Old timer here, was looking for a post on cleaning the 17 but really anything rim-fire. Since 1952 I have cleaned very little, sometimes I grease one if it's going in storage. Ive never anything but bore snaked my four 17's. I do ballistol the bolt and trigger below zero, but the bores I never touch, never. Keep it smoked you never know when the adversary is out the window doing something naughty.
I.E. I just don't clean much of anything but snake a bore, large and small.
