Gun storage Horizontal - vertical

Just wondering if it makes a big deference which direction the gun sits . Was in my gun safe the other day & seen some weeping happening on the air tube & shrould- was just thinking what was going on to the inside of the gun . Have never seen the manufactures mention this but was just curious . Seems that the oil residue would eventually build up more in one area if the gun was not exercised for a long period . I realize the O-rings are set in a particular spot but what about the inside of the valve body ? As I mentioned just curious & thanks in advance .Tried the search bar but never had any luck since it was changed wish it was the same when I first joined
 
I'm not sure if there's a 'correct answer' for this one, but... 
I throw kickstands [bipods] on all of my rifles so that I can always keep them positioned horizontally. 
Why? Here's my thought..

IF any water or oil has entered the tank, or IF it is created after the fact [condensation] 
Laying horizontal will keep the water/oil limited to the base of the bottom of the tank..
I consider that to be a 'safe place' for it to be.. [lower than / away from the tank-valve]

If the rifles are positioned vertically, then any moisture/water/oil would do what? 
It would fall downward and pool up.. Where? At the valve side - closes the gun..
No good, IMO.

Then as for a storage pressure, I try to keep 150-200 bar in them at all times.

Have you ever seen moisture in the inside of a tank?
 
I have always stored shotguns and metallic cartridge rifles muzzle down, mainly to prevent oil from seeping into the stock. Most air rifles are so darn fragile in their barrel structure, I fear POI changes if stored on the muzzle. Most of them are stored either horizontal in their cases, or muzzle up in the cabinet. Frankly, I don't think it makes any difference. Keep some lubricant on them, but not enough to migrate where you don't want it. 
 


Also for your info I have-----

Ohhh yeah!
[I'm a metal worker] so I know all too well about metal oxidation / rusting..

If/when I keep an air rifle for an 'extended' period of time, they'll get a thorough internal inspection just for that reason.

**Barrel down storage - That's another nice idea. [It would also keep any excess moisure/oils away from the cylinder's / tank's valve]

Hmmm... I was already considering doing a few wall-mount horizontal setups in my apartment.. Maybe I'll change to vertical..

Re-do the place to look like a cave, then hang all of my rifles from the drop-ceiling-brackets, so they look like stalactites?! 🤣

This is how I store mine. Not saying it’s the best, but it works best for me. All the weight is on the bottom hook, when I found a good balance point is how I set the top hook, so no side to side pressure was applied to the shroud. As far as air pressure, 230 BAR at all times.

my 25 wildcat is stored this way in the bedroom closet, behind the door.
