Store Co2 rifle empty or full?

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.

Hi Graeme, when running low on gas I usually just slacken the cap on my Ratties slightly, which lets the gas vent safely out.

And, as above, the cap shouldn't be on that tight. However, contrary to the above, as far as I was led to believe, you dry fire it once to pierce the bulb, which is what I've always done on mine, without ever a single issue.. So, cap on, just a smidge more than finger tight, dry fire once and go!

I've never had a problem leaving 12g canisters in.

I've also removed partly filled ones - as long as you are careful and release slowly then you are unlikely to injure yourself. Not recommended for Crosman and similar with end caps but ok for pistols with capsules in the magazines.

The best solution is found on my QB78 Match rifle - when nearly empty you can use a key to open a valve to safely release the remaining gas which saves having to dry fire it.
