Storing pcp air rifles and pressure

Hi everyone, I'm new to PCP Air Guns. What's the best way to store them in terms of maintaining the tank pressure? How long can I store them with touching them? Anything you learned that works best to store them if not used?
You can store them until the 0-rings die of old age. I keep mine under pressure, well except for one, it degasses itself.
 
I normally just store them at whatever pressure they are at when I finish shooting. Sometimes I air them up first to be ready for the next shooting session. I don't think it matters as long as you keep pressure in them to seat the o-rings so they seal. Usually I take the magazine out just for safety reasons. Sometimes I leave it in but no pellet in the barrel. I don't store my PCPs cocked. I worry it could reduce the hammer spring force and it doesn't seem safe.

Some pressure is much better than no pressure. An empty pcp is an open invitation to moisture and seals drying out.

Your gun is made to hold xxxx amount of air. It won't hurt a thing leaving it filled at max. If something does fail, it was going to anyhow.

I have had guns that will leak all the way down if they don't have over a certain amount of pressure in them, but hold fine if they're filled to max. That usually means the poppet seal is getting worn.
