I have about 16 or so total. Centerfire, Rimfire, Pistol, Shotguns, and Muzzleloader. All are clean and wiped downed. Barrel isn't oiled inside, due to dry climate. Most are all in a safe that is bolted to the floor. There is no way in heck anyone is getting in. A few are around the house for defense. Also in the safe I have a dehumidifier, not that I need one, but I suppose it doesn't hurt.
