Ammo in your car

[peloe16]

maybe this is a dumb question and i searched for an answer, but since the weather is getting warmer and the interiors of cars out in the sun reach very high temperatures, what happens to ammo sitting in your trunk when it gets to be 120 degrees in there?

It gets warm.

Seriously, nothing. It takes much hotter temperatures to set off ammo. The powder may degrade a little faster than otherwise, but its life will still be measured in decades.

There was a thread on this about a week ago. Do some searching and you should be able to find it. My thoughts are no, it should be a problem. How are you planning on storing it.(lockbox, bag, ect...)

 

[XtremeVel]

was just talked about not too long ago. Don't worry, but if you would like to read more about it, theres a recent thread where it was covered.

Our troops carry it regularly in much hotter temperatures than we see Indiana. You're OK. As a cautionary measure, shoot your carry ammunition at the end of summer and winter.

Figured I would post the link to be helpful since the search doesn't always work for me either. https://www.indianagunowners.com/fo...loading/85995-storing_ammo_in_high_temps.html I hope that helps

This was the result of one 12 gauge slug being left in a car in July.

A little misleading...

they later determined that there was also a Glock in the glove box.

Yep, this! You should be good to go!

That would have taken several Glocks. I don't store mine in close proximity because they are known for sympathetic detonation when one goes...

I've often wondered the same thing but never been worried about it enough to take my ammo out of my truck. Always shoots fine and never had one blow up! (knock on wood now)

thanks guys...i was searching for ammo in car and not ammo getting hot i guess so thats why it wouldnt come up. so i guess there isnt much to worry about.

For the most part, yeah there's nothing to worry about. I did get a follow up email from a Winchester Rep. Her personal suggestion was to rotate the ammo out at the end of the summer unless it has been a especially long/hot summer that year. In that case it should be rotated out about 1/2 way through the summer. The box you are rotating out should only be used for target ammo and not relied upon for personal protection. Her reason behind this was because the powder starts decomposition at 122f and may result in a few "failure to fire".

Keep in mind, she said this is her PERSONAL SUGGESTION but with all the facts obtained recently, this is advice I'm going to follow.

that makes the most sense. and it is probably a good thing to do.

warm ammo will develop slightly higher pressures. This is a trick that some folks use to make MAJOR across the chrono.
