how many shots from a single Co2 cartridge ?

[DBOdude]

in a stock 2400kt gun from the CCS how many shots are typically had from a single Co2 cartridge in .22 ? and also .177 ?
also , correct me if i'm wrong , but just to double check ..... barrel length should have no effect on this .... correct ?

The best I remember I got close to 40 shots. I have some chrony printouts around here someplace. I put them up where I would not forget where they are, now cant find them because I don't recall where they are.
  barrel length doesn't matter, it's all about the valve, springs, TP port, hammer weight, etc. How long the valve is open is what is determining the CO2 used and the total shot count.
