I believe he did but I don't remember for sure. I have always been one to clean my rimfires on a regular basis but some of my friends are in the "Don't ever clean" camp. I usually clean every one to two hundred rounds which lots of times is after a day shooting off the bench.
Pretty much similar here, but a lot depends on the action type. For me, bolt actions and levers stay much cleaner and functioning better longer. Semi-autos get very dirty quickly, and depending on ammo, and can cause more malfunction issues. Semi-auto pistols get real dirty very fast from all the blow-back.
