If I'm gonna hunt with mine after a range trip, I don't clean it until after the season unless it gets wet while hunting, otherwise I clean em after each range visit with few exceptions, most Handis shoot best fouled, my .17 Sportster rimfires shoot best fouled and don't get cleaned until they quit shooting good, it takes a few rounds thru them to start shooting their best, so they don't get cleaned much at all.
