Store Co2 rifle empty or full?

[peddy]

Do not leave a 78 ungassed, your seals will dry out. The capsule are pierced at both ends of the tube and the gas is held in the tube. This keeps the seals from going hard. There is no seal where the seal butts up to in a 78. Whereas Crosmans are fed gas direct from the capsule one shot at a time, so a totally different method of gas release.
Take a look on UKCAF, we tend to know what we are talking about with reference to Chinese airguns.

My thoughts exactly, my 78 always has gas left in it and never leaks, all my pistols are never stored with gas or empty capsules.

Thanks guys, after reading all the comments I think I'll go for leaving it gassed up. I thought I'd read that somewhere, but I was just a bit dubious with the previous owner having left it gassed up & then the seals going the first time we changed the capsules!
Thanks for all the advice.

I have lost count of the second hand co2 guns I have bought that have 'held gas for ages' and when you take out the old capsules the new ones dump gas everywhere.

I give them to Baz to sort.
Without him I would have an excellent pile of junk.

Well after reading this thread I'm still no wiser, leave or unleave all I no is my dad a few years ago left a bulb in his EB pistol for a few weeks and it developed a leak. Personally I now always remove. Right or wrong, no bloody idea

I have a umarex pistol that takes CO2 cartridges, if you remove a part filled cartridge does it reseal itself when you remove it or do you lose the remaining gas?
I have only changed the cartridges when they are empty.

Hi Mel on no account try to remove the 12g canister when it's partly filled as it doesn't seal... the freezing gas will cascade all over the place and may cause injury. I'm not sure what the situation is with the large 88g canisters as I haven't ever used them.
The only exception I'd make to what I initially said is when the gas is almost expired in my Crosman Ratcatcher and it's almost empty I remove the knurled cap and I 'Dry-Fire' the remaining tiny amount of gas and that usually makes the canister pop out of the casing thus making it easier to remove.

Hope things are well with you, Mel,

If you can remove the cap and the capsule stays where it is then its on too tight! You only need it on enough to burst the end and sit on the seal, anything more is too much. THAT is how you end up with knackered seals.

88g are the same story, a rather expensive waste if you believe the hype.

Cheers Graeme, will do as you say regarding the capsules, I'm fine thank you, apart from a Stye on my right lower lid, but i'm treating it with medication.
Guitar is not going good though, fat arthritic fingers don't help, but i have just found out that a neighbour teaches guitar at schools and he has offered to show me a few 'pointers' as he put it so i'm going along with that.

Some of the chords seem impossible to reach though, guess i've started too late but we will see how it goes.

Hope you are keeping OK, by the way got the CD set of Ken Sykora recordings his family have produced, contains a lovely glossy booklet and two CDs of his recordings.
It's very good and as the three EPs I bought back in the late fifties when I was fifteen are very scratched its nice to here his playing clear without crackle and scratches, the CDs reproduction is very good and almost sound like the vinyl used to.

Cheers

Mel

Well I've learnt something useful - in that we all have different experiences with CO2 pistols and 78 variants; very odd, it would seem no-one is right and no-one is wrong. I guess that that's all the joy and idiosyncrasy of CO2 owning!
