I'm between Swampghost and hogdogs. I don't do a take down and serious cleaning after each time I shoot, but I do swab the bore before the mildew sets in. It depends on the frequency I'm shooting. It may vary from infrequently to five days a week. With an O/U, the friction surfaces are wiped before the gun leaves the range and re-lubed when the gun is re-assembled. With an 1100, the mag tube/gas cylinder gets wiped clean before the gun goes in the case. A pump gun is more forgiving. As far as the bore is concerned, I try to remember to hit it with a fuzzy stick at least once a week if active.
For comp shooting, I learned years ago to clean after the tournament, not before. Something as simple as an infinitesimal bit of lint from a cleaning rag caught in a sear can result in a rude surprise. For a freshly cleaned gun, practice first so you know everything is working properly before the tournament. The same practice can be applied to field guns, too.
