CO2 in this heatwave

[coburn]

Has anyone noticed an improvement in power and number of shots with a CO2 Pistol in this heatwave.

Of course this may only apply down south!!!!

I'll have to experiment this weekend Any excuse

Its like an oven in my garage but I havent noticed much difference to shot count or power

CO2 pressure could be at 1030 lbs sq in at 30 deg C, whereas pressure in cartridge with average temperature of 19 deg is around 800 lb sq inch.

Hmmm

I agree with the previous post, I've just looked again at the article in the first Airgun Digest and you're figures are spot on. The difference in pressure between 71F and 86F is quite marked.

At Lea Valley last saturday (bloody hot) we had a few issues with 1911's, 3/4 were having problems - mine in particular I think was down to too high a pressure in the valve.

Just a quick question about co2 when you'r shooting is it best to keep the cartriges in your pocket to warm them up.

It certainly seems to work on those cold winter mornings. But be mindful of the safety issues involved when keeping pressurised containers on your person.

A big fat customer came in today with his Tan Witters, "have a go on this, I've rifled the barrel with the wire cleaning rod!".
So I had a go, and it seemed a lot more punchy! But now I'm realising it was the temperatures...

What heatwave?

Is the size of the shooter relevant?
Or just to make me laugh.

no, it will make no difference, after the first shot it will cool down and if the temperature isn't allowed to stabilise to the same as the air temp your poi will not be consistent

I have only had my TFW pistol a few weeks....and I have quite a few jamming problems with it, then I came across a few threads of people saying they have been having problems with jamming etc. when shooting in warm temperatures. Hadn't occured to me this could be the issue, I'm an essex lad and it's been pretty warm in these parts since I got my pistol....so I had a go shooting the gun late in the evening when the temps had cooled, and guess what? no jamming at all. Unfortunatly I could only fire off a mags worth as it was fairly late and didn't want to upset the neighbours..so either a coincidence that it managed to get through a whole mag without jamming or the temps are expanding a part of the gun causing jamming. I have a theory it could be the spring in the magazine expanding and becoming stronger and pushing a touch to hard on the BB's and causing them to spring out a bit readily...or am I completly way of the mark?!

My experience is entirely the opposite.

I have two TW Witnesses and they are bloody awful for most of the year - they jam, power drops off and I feel like throwing them at the target to get a result.

In the hot weather however they both perform perfectly ( I leave them to warm up after each 10 shots).

Especially when next to your "wedding tackle..!"
