I load my ML ( a cap lock) the night before opening day and put an industrial masking tape dot over the business end of the barrel, it rains here in the upper PNW during the season and it stays loaded for 3 weeks or until I shoot an animal, the rifle stays in my locked truck when not in the field avoiding the temp change from outside to inside my motorhome, the last day I hunt if not successful an old stump gets ventilated, I quick patch the barrel with some CLP and head home, clean & oil it well then back in the safe until next season.
