Southpaw I always put my gun in the garage the night before the season opens. This allows the medal barrel to cool down close to the outside temperature. The next morning in the garage I use dry patches to get out any moisture and oil. I then fire two or three primers into a patch of course to keep down noise. You do not want to wake up the war department at three am. I then case my gun keep the truck cool on the drive to my hunting area. Once there I use a couple more dry patches to get any remaining moisture in the barrel. Once I load my gun I never take it into the house till after the season. To do so will invite moisture into your powder. This may seem like a lot of trouble but I have never had my gun fail to fire doing this.
