I agree with GB on this. I used to clean a LOT, and rarely let a rifle get more than ~50 shots down the tube (unless on a specific shooting outing) without cleaning. Even at the range, I'd clean. I don't now. They don't need it. In fact, in most cases one can prove to oneself that their rifle prefers to not be squeaky clean. Not always, of course, which is why I agree with GB.
