    Exceptable temperature ranges and storage containers, metal box vs the hard plastic.

    I`ve done some research but I want to hear real world exerpience on ammo storage. Thanks!

    I have been keeping my ammo in my shop in Plano ammo boxes, it`s high and dry but there is only heat and air in use if I`m there and Oklahoma can be a little extreme at times.

    I know a few people who lost a considerable amount of ammunition in past hurricanes that used plastic boxes.

    Even metal surplus boxes seals should be checked. If they are cracking they're toast regardless. If the rubber seal appears dry, apply a thin coat of Vaseline.

    I store ammunition that is placed in vacuum seal bags with a triple seal, then placed in a metal surplus ammo box for long term storage.

    And to be honest, 5 gallon pails with lids work well too as long as they are stored in a dry location.

    This is an unlikely website for this information, but I'm sharing it with you nonetheless for the educational value.

    I have ammo in factory paper boxes at my cabin tbat has been there for many years through temps ranging from 100+ (closed cabin, no shade) in the summer to well below 0 in the winter. It still shoots fine.

    If i lived where I thought flooding would be an issue I would probably use water tight ammo boxes, esp for shotgun ammo.

    You're probably right Mike. Shotgun hulls are more susceptible to water damage due to the crimp and the different materials that make up the shell how they're joined.

    I tend to err on the safe side where it pertains to water though. I treat all my long term ammo storage like it's going to be stored in a submarine with a screen door.

    I have read reports from the military that concluded that high temperature is more detrimental to large ammo caches than anything after so much time in the litter box in the middle east. I think the failure rate (dud/misfire) increased to 5 or 7% ??

    I don't really recall the exact counts right now, but it was enough to know that I don't want to store my ammo in my attic for long term.

    Cool dry places seem to be pretty universal storage recommendations for nearly everything. Appears ammunition was no exeption.

    All my ammo is stored in GI Ammo Cans after the contents of the factory paper boxes are marked then dumped into plastic Zip lock bags and sealed...then the cans are stored in a cool dry spot in my basement...knee level and above...on a wooden rack I built. Has worked so far...

    { +1 on petroleum jelly lubrication of the seals on GI cans }

    BTW...I don't think the Plastic "cans" have water resistant O ring seals like the GI Field Cans do.

    From my understanding modern ammo is very resilient. Even submerged in water.

    Heat tends to be the biggest factor in degrading the powder inside.

    I have some ammo in surplus ammo cans. But most are still in shipping boxes that were delivered.

    I live in a second story apartment and ammo kept in a locked closet which the apartment is regulated in temp.

    I haven't had any issues.

    I keep some ammo in my gun safe, and have three small Sentry containers (locked) that I keep the rest in.

    Any idea what the seal on the GI cans is made of? I've heard that petroleum jelly can degrade O-rings over time.

    What grade?

    I have no idea.

    Most of mine is in ammo cans, in a non temp controlled barn. My reloading powders are in a non working upright deep freeze.

    Regarding shotgun shells,

    The Olin (Winchester) Mil-Buck shells I've been buying are the only ones which are actually hermetically sealed.

    Every other shell has a little hole at the crimp. Roll crimped shells are possibly better, but they have a little crack all the way around.

    But those Mil-Buck shells are heat sealed after crimping and I believe they are completely waterproof.

    Now the Box they come in wouldn't stand up to a good sneeze.
