Years ago I stored my reloading dies in the basement by my reloading bench and one set developed rust. I then started storing them upstairs in an ammo box on a shelf w/o problems. I have since installed a dehumidifier in the basement and it makes a huge difference. I'd like to move my dies back down to my reloading bench. I think the dehumidifier might suffice but I am thinking to hedge my bet by putting a Brownell's Rust-Blox tab in each die box. Is there any reason I shouldn't. Thanx for your help.
