Up to you.  Are they sealed?  Are the Secure?  If its not secure then get them if they are Sealed in Ammo cans then they are fine.  If you are worried get your ammo.

Leave it there.  If it is dry it should be fine.  Bring it in when it is warmer.  If you do decide to bring it in now, wrap it in plastic, bring it in and give it a few days to normalize to room temperature.  Cold is not an enemy of properly stored ammunition.

If it's in sealed cans, no problem, no moisture inside=no condensation. If there is moisture in there, it will condense no matter what you do when the temps change.


I drug 1000's of rounds from post to post and back and forth from my parents homes when I was deployed over the years. It's all still fine. I have 7.62x39 thats been in .50cal cans for nearly 22 years, in basements, garages, barns and bedrooms, no problems. Shot some this weekend. Keep it in cans, keep the cans closed, all will be good. In the sand box, depending on what weapons your unit has, you may see ammo thats been in cans for decades, and it will shoot fine. I have some 30.06 that I bought from the CMP when I bought my 1st Garand in '86, purchased 3000+ rds that where 25+ years old THEN... shot some at a Garand match in October, no problems. In fact in my Garands, I have never shot a round NEWER then '68, and no telling what the storage of them has been like over the decades.

the cold wont hurt the ammo, condensation and water will.

The afghani's are still firing that spam can ammo at us from the war with the soviets in the 80's That stuff has been getting rained and snowed on and rosted in 130 degrees for the last 27 years it still works.

Heat is bad, cool dry is good.

+1, read my mind.

I'd much rather have my stash in the cold than in extreme heat.

Condensation is the enemy.

I'll go out on a limb here and guess the Ruskies didn't store all of their ammo in heated warehouses and mutha russia gets colder than most of the USA.

I have a great idea, just shiop them to me Ill take care of them for you

Agreed on both counts...

Bring it in....maintain a constant temp. Cool and dry is best. Hot and cold fluctuations out in the garage will deteriorate the powder over time.

If you're that worried about it, just ship me the cases and rest easier.

Your ammo is fine in the garage, cold will not hurt it.

If that happens, you aren't shooting enough.  Better off selling your ammo and guns and raise chihuahuas.

One of the many joys of bachelorhood is keeping all my ammo in the 2nd living room, also known as my reloading & weight bench room.  I just need a line of Dillon's setup in there and I'll be set.
