If you use shotgun to actually hunt they need to be at least checked over, I have taken a lot of reeds a grass out of actions. If I go on a extended over night hunt I will clean my shotgun every night. If they are sitting in the gun rack they get wiped down every few months. My deer rifle I probably only shoot 3 bullets a year so I should be good running a patch through the barrel every few years. Had guy who bedded my 25/06 tell me if it is shooting good leave it alone unless you shoot a couple of hundred rounds.
