Example of moisture in a foam gun case.

I grabbed a few guns out of the safe to go shooting. I keep my gun cases in a closet, inside my air conditioned house. I pulled my 308 out of the safe and put a it in a hard case and went to the range. I put the cases on the bench, set up targets and started shooting. It was about 1/2 an hour until I pulled the 308 out of the case, which had been sitting in the sun. Be advised! The forum Boss has posted warnings about foam gun cases holding moisture. Here’s a pic of the gun when I pulled it out:

I haven’t had beads of condensation that bad, but have seen firearms blush. It’s the same as eyeglasses in the winter going from outside cold to inside warm air. My car won’t accept hard cases, so I only use soft ones, which don’t seem so bad. I open the zipper a bit when I get to the range to let them warm slowly which seems to help.
 
It sounds absurd, but it's not at all uncommon to have an Ambient temperature of 90° and a humidity level of 90%.

Others have likely questioned, at least to themselves, why I talk about keeping bores well treated. This is why.

This happened inside the case. I took the pic 30 seconds after I pulled it out. Besides, this is the Texas Hill Country. It’s as dry as a popcorn fart!

There’s that phrase that drives me nuts! Wifey says “Turn the AC down! “ I ask what she means! It’s 72. Do you mean you want it colder at 70?
 
Foam is notorious for holding moisture. Many years ago, I had a friend leave his prized rifle in a foam interior gun case for several weeks in the summer and when he took it out it had the beginnings of rust forming on the surface.

Using a brass brush with WD 40, we were able to remove it without marring the bluing. However, the inside of the barrel undoubtedly had more*. But it appears a few shots and cleaning restored it since performance was not affected.

* Before the bore scope were widely available.

WoW.

I've had condensation form within a minute during high humidity. I'd have never guessed it could look like that in low humidity.

Yeah I'm 77° in summer for ac setting.we sacrifice being a little warm to save in power bill .I'm thinking it would be cold as crap from your house or truck for that condensation? Idk

We had some bad weather come through and I had a new scope fog up kinda unexpectedly I was testing on front porch.kinds shocked me but no sweating like that

Interesting I guess it can happen. definitely best to check many times a year

Thanks for posting definitely good reminder to oil your guns

Makes me want to go check mine in cases
 
Air valve night be stopped up or covered up .
Mine doesn't do that in a plano v700 that it lives in 100% of the time.

wowser i never had anything like that happen!! ——at least i dont think i did—- i am old and forgetful though
 
Once upon a time my son's .410 shotgun go left in a foam lined hardcase under my bed for a few weeks. The exterior of the barrel was badly rusted when we opened the case (after remembering it). Oiled it real good and used 0000 steel wool to clean it up and it surprisingly held the bluing although it looks to be 150 years older than it is. The bore was still perfect so we really dodged a bullet....no pun.....

I've seen it that bad many times. Driving to the range with ac on and take rifle out of truck they will look like that no matter what kind of case it was in. I'm in south Louisiana and we have high humidity.
