I have stored my various types of ammo in my gun safe for the past years. Now, my firearms purchases have begun to overcrowd the ammo space, and I need to move ammo out of my gun safe. "I have always heard that you are not supposed to store ammo in the gun safe, but I did anyway". What are some options for ammo storage, considering economy and environmental conditions? I have a couple of the plastic and metal ammo "cans", but was wondering what you guys use for storage. Most of my ammo is in the 50 round blocks, whether it is 9mm, 357 mag, 38 special or etc. Especially interested in environmental/waterproofing seal. Thanks in advance for you comments.
