Storage of your PCP

[Graybird66]

Hey all, noob here.  How are the majority of you storing your pcp weapon?  If you are putting it away for an extended amount of time are you bringing the pressure down or just not worrying about it?  Do you notice a significant amount of pressure drop over time?  Sorry for all the silly questions, just trying to get a grasp on what I can expect.

Thanks for your time!

I always store my PCPs with around 100 BAR, I can still pick them up like that if I need to take quick a shot at a pest

It’s best to store them with at least some pressure because it keeps the seals pressed against the atmospheric side.  Same thing with single- or multi-pump pneumatics…it helps keep the seals formed to the tube.
 
I personally keep my PCPs near full pressure.  The argument can be made that full pressure increases the probability that the O-ring will extrude and fail but I see that more as evidence that something isn’t right to begin with…that the O-ring material or durometer isn’t right or the parts are poorly fitted (gap too large).
 
The saying goes, there are PCPs that leak and those that haven’t leaked yet.  This question comes up on a pretty regularly and based on the myriad of anecdotal evidence I’ve read, there’s no compelling reason to prefer storing a 3k PCP at 500psi or 3000psi or anywhere in between so long as there is some modest amount.

Full pressure and in gunsafe.(?) Checking sometimes if some gun loss some pressure

I store them fully charged as said to check for loss of pressure over time..
I make sure the hammer isn't cocked but leave the bolt Open.
And keep them in their separate plano guntuff cases with padlock.
Store pellets/ammo in separate cabinet and make sure none of the guns has pellets in mag.
Modern PCP airrifle are not a BBgun and can be just as dangerous as a firearm.
Just because it's an 'air' gun doesn't mean one shouldn't use proper discipline,specially when there are kids around..
Seeing an adult handle guns with care teaches them to respect the responsibility whilst handling any gun.
Just my 2ct...

My rifle has a 3000 PSI fill limit. During the warmer months, when I shoot nearly every day, I top it off to 3000 PSI before I hang it up. When the cold weather comes around and I might not shoot it for a few months, I usually leave it around 2000 PSI after my last shooting session of the season. Been 5 years of doing that now and I haven't had any trouble with the seals or the valve.

Thank you all for your inout.  It is grately appreciated!

I store my Synrod .22 in the front of the gun safe, at about 2500psi, ready to go, in case I see a squirrel.
Three years like this, and no problems.

The o-rings are not the issue at high pressure it's the poppet, mostly made from delrin that will slightly "mushroom" and be pressed into the throat of the valve.
The rifle will still fire perfectly but velocity will decide depending on the amount of poppet deformation.
On a 8mm poppet there's 234lbs of pressure at 3000 psi... Storing at 1500 psi halves that.
