Strange 2240XL Issue

[cjtamu]

Put our 2240XL carbines outside in shade this morning to acclimate for a bit. Put Crosman CO2 carts out with them. Hot, was already 90+. Put carts in, pierced them. Loaded a pellet into mine, cocked and fired, pellet didn’t come out. Sounded like when you’re almost out of CO2. Fired several more times and pellet finally came out, weakly. Loaded Kim’s gun and it did same thing, only pellet never came out. Decided to remove carts to poke pellet out and the end cap was so tight I had to use a big screwdriver. I never put them on that tightly. Both had CO2 left but didn’t seem to be a lot of pressure. Brought guns back in. Just put a Daisy CO2 cart in each, took them out and they shot great. Had just opened a new box of Crosman carts. Is it possible I got a bad box or a box with a few bad carts? Or will these 110 degree heat indexes affect things this way?

if could be the pressure in the valve overcame the hammers ability to open the valve completely or even enough to fire the pistol
CO2 has a goldilocks zone and because the pressure was there the caps do not come off
i would have dry fired it till it adjusted the pressure

As stated over at gta, valve lock is the most likely culprit. Try the crosman carts again at room temperature. When you load a hot cart, you are putting a lot of pressure on the face seal and best case scenario is it creeps around the poppet, worst case is having to reseal it.

Thanks fellas, crystal. Leaving the carts in our 66 degree house till I’m ready to load them. Hopefully that’s enough.
