I have seen people bury guns in PVC pipes with desiccant packs, so I imagine it would work in a truck.

One of the biggest causes of rust on guns is people touching the metal before they put it away. I always wipe my guns down before I store them, no matter how or where I store them.

 

I would never store one of my guns in one of the foam egg carton padded cases. They are notorious for rusting guns. The foam holds moisture and makes the guns rust like crazy. My bud did that with a Remington pump shotgun and in 6 months its was coated in rust. Another guy I know stored a like new Winchester 22 mag lever action like that and did the same thing. Turned an $800 gun into a $300 dollar gun.

 

every seasonal change, i take a couple of days to go thru all my guns to clean and add clp. Costs too much not too take care of my collection that took me a lifetime to acquire.

Gotta be real careful on what you use on a gun that sits for a good while. Seen to many ftf's cuz firing pin was gummed up.

 

I'd use a silicon impregnated "gun sock" in addition to some dessicant.
Funny idea....I could probably vacuum seal a gun. I'd have to use the "make your own bags" roll.
Mags and ammo could be done that way as well.

Also, Big 45 Frontier metal cleaner is FAR better for your gun than steel wool. Won't scratch, won't mar any bluing (I know you don't have any).
It's a loose coil "composed of a proprietary alloy containing stainless steel, nickel silver, monel (a corrosion resistant nickel based alloy), and zinc. The alloy is effectively “harder than rust but softer than bluing.”

It's also good for bore cleaning when they get extra nasty.

That is what dad did with the shotgun kept in the boat. Not exactly a quick access option but out on open water you usually see any threat approaching in time.

 

I wiped a Mauser barreled action with light coating of cosmolene grease, put into a Brownell's tripple layer gun bag and sealed it.

Then I put the bag in a 120mm Rocket box,and burried it my pasture in 2007.

After I retired and moved here in 2015, I dug it up and found zero rust.

We get around 40" of rain each year, so I this was a pretty aggressive test.

 

I have an ex PoPo Mini 14 GB stainless that lives in my truck. Like most police weapons it has dings and scratches but it mechanically excellent. I just pulled out. I have not seen it in a long time. The truck is rarely driven.
It's been kept in one of those foam lined clamshell cases that sometimes come free when you buy a long gun.
I know this is far from ideal, but all the others don't sleep out there and the Mini does.
There is a small ammo can with 420 rounds on stripper clips and the blued Ruger mags are also in the can.
The mags show ZERO rust even though they are not stainless and are kept in the same conditions... but in the sealed ammo can.
I did find a few freckles of rust on the barrel of the Mini and a little more on the non stainless bayonet mount and rear sight. Some steel wool and osfo will cure all that.
I need to do better on the container for the Mini though.
What do y'all think of a PVC pipe with a threaded adaptor on one end? Like a burial tube. Although if I'm burring mine both ends are getting glued on with no threaded end cap.
Anyhow it's the temperature swings and moisture condensing on the metal that is the problem.
I can put in a desiccant bag the pipe to remove the moisture. There are also those rust inhibiting bags. I'd still need the pipe because the bag wouldn't stand a chance behind the seat in my truck.
This is not something I need fast access too.
The Ruger SP101 .357 has no rust anywhere on it and that has lived in various vehicles year round since some time in the 1990's.

I have kept the same guns in my truck for years, from well over 100 degrees all the way down to 0 degrees and never had an issue.

 

How come you don’t just bring it inside when you get home? Not very discreet, I guess, depending where you live. Get a folding stock and put it in a gym bag and move it back and forth to your truck in that.

 

It doesn’t come inside because it’s the outside gun. I want a gun in that vehicle wherever it is.. usual residence, other house etc. That truck is seldom driven. It’s a 2008 with 41K miles on it.
I have 1/3 if my guns somewhere else.
Theft, fire, red flag laws… you gotta be crazy to keep everything in the same place.
I have a spare stainless mini 14 also.
I’ll probably go with a PVC pipe. It will be easier to access that way anyhow. It can on the bottom under my tools, shovel, ropes, etc.. just open the little “suicide door” on the truck..Twist off the cap and pull the gun out. I’ll keep a wrench in there that fits the cap. It’s not a full 4 door truck. Space behind the seat is limited. What I put back there doesn’t seem to be.

 

What about putting it in one of those silicon impregnated gun socks?

 

I’ll be using desiccant and the silicone sock also. The Mini 14 is easier to store in a pipe than an AR15 because it’s much shorter in height.

 

I have seen a video of a 10-22 rifle that was buried in the US desert south west for over a year or so.. This in the pvc drainage pipe with a screw cap.. Frankly the system worked well it seems..

Problem up here is to bury any cache we have frost that goes 2 meter or more deep... With that in mind I have been experimenting with above ground cache of different kinds... So 50 caliber and 40mm caliber, 120mm caliber ammo cans work well above ground.. My next experiment will be with an old up right freezer...

Me too. Even if I could hand dig a hole deep enough to get below frost line, how would I get it out in winter?

 

With the cost of pvc and caps and then more than doubled due to increase in size, that will be expensive. $150-200? That’s just a guess. Maybe a mortar can with the bottom cut out and the placed over the pvc? That way you could just pop the top off. Could even sink it in concrete. But then you could find that with a metal detector.

 

Yeah…10” pipe is $30-$40 a foot out here.

 

I think what you want is stable temperature if possible. In the ground that’s below the frost line. That’s impossible in my truck.
70 degree swings are possible on some winter days.

 

Just mount a gun rack with padded hooks inside the cab on the rear firewall. Oil the gun and done.

 

I have carried a long gun of some sort in my truck for the last 30+ years. The last few years it has been a Glenfield 22 with 16" barrel I bought from the local paper for $50. It just goes in a soft padded case under the rear seat of my truck. Or if the rear seat is folded up I slip it in between the seat where it folds. I also have a small pouch with ammo, knife, compass, firesteel and few other supplies in case they are needed.

Those padded cases are OK for transporting a gun but not very good for long term storage. I have seen guns stored under a bad in one with the lid propped open so air could circulate and that may be OK to do.

 

I bet you could just wrap it in an old cotton sheet that is lightly oiled, and then put it in a heavy trash bag and it would not rust for a long long time. throw a few dessicant packs in the trash bag and duct tape it enough to hold it kind of tight. sometimes less is more and easy and simple is better.

 

That could be an excellent example/demonstration of spontaneous combustion.
