Gas guns and Altitude

[Jbone 11 11]

Don't know where to post this... so I'll stick here for now.

I was wondering if anyone knows how gas guns will react when brought up to a higher altitude, like 2000-3000 meters? No flying involved, simply driving up (from sea level) and playing in a mountain environment. Im concerned that the gas in the cartridge will expand and maybe blow any gaskets/seals do to the increase of pressure.... or worse!

Thanks,
Jbone

Leave them empty till you get up there, then fill them. Problem solved!

I dunno. It seems like you'd probably have problems with expansion of the gas if you're going from 0 meters ASL to 2000 meters ASL.

Keep 1 or 2 shots worth of gas in the mag (like you should be doing anyways) and fill the rest when you get there.

If you know anything about commercial air planes you'd know that the fuselage actually expands slightly when you're up in the air and those can take a lot of stress.

Now scaling that down to a gas mag... I'd be careful. It's not like it's going to randomly explode but chances are it wasn't manufactured to go from Sea level to 50,000 ft ASL, most likely it was manufactured to more realistic tolerances based on "normal usage" eg. Sea Level to a few thousand feet ASL.

Hmmm, yeah I was thinking of filling up when I got there, but by that token, wouldnt the gas cylinder (the one you fill up from) itself be effected as well?

guess Im gonna have to do some more research : /

Thanks for the help though ; )

Don't bring a full can of propane up with you. Leave some room for expansion. These things also usually have emergency release valves so that they don't explode in situations like that.

Where Green Gas doesn't and one guy in Canada had a can blow up in his convertible and pop a nice hole in the roof. Propane and AI adapters FTW!

I wouldn't leave them empty while heading up. Always leave a touch of gas in the mags. It wont be enough to have any worries about the mag blowing gaskets or valves on the way up but it will keep the gaskets pressurized so they don't shrink and/or dry out.
