Depends on the humidity in your area, living here in the PNW it's pretty humid, during hunting season(if it isn't raining, I load then when I'm done for the day I lock the rifle in the truck loaded, don't want to take it in to a heated camper or motor home and let condensation build up in the barrel overnight, I will hunt with it a second day, if no meat was made, I shoot that ball and load out, quick wipe and will reload in the am, leaving the rifle locked in the cold cab, if it's raining, I do it daily
