What I did this year was leave my ML hanging in the garage with the triple 7 pellets and bullet in it, took the primer out. If it was really snowing, I tried to protect it while hunting and wipe it off in the garage. Yes, if you bring it in the house, condensation will form. I did unloade it and wipe down the inside of the barrel after it had hung in the garage during several days of bitter cold and snow. I thankfully had no misfires and how I treated t must have worked well. Yes, having a primer not go off was my concern for sure but it went 3 for 3 on deer this season.
