temp & Co2

[mcc1961]

Can you tell a difference in the velocity of a pellet in 57 degree(high for the day) fall weather  and summer weather?

[grumpy]

I can in my 2240. Once we get some warmer days I'll post the difference.

Yep, the hotter the Harder shooting...

Here is the infamous chart that gives the relationship between temperature and pressure.

warmer weather will yield higher shot counts and higher velocities(fps/fpe) as cooler weather you will see lower numbers all around

Yep on a real cold day your pellet can be seen leaving the barrel,if I am hunting will take out a pumper & leave Co2 rifle at home if temp less than 15deg C
Its been known to happen at very high temps (back of a car in summer months) that valve will lock up,the force of the hammer cannot overcome the high pressure holding the valve stem shut,happend to me once,had to put pistol in fridge for half hour. But on the whole Co2 rocks
