Im interested in a semi automaatic pellet rifle which i assume use CO2 cartridges for power.
Iwould like to get a brand that is accurate and has the highest possible fps as I have a firearm license.
Are there different co2 cartridges for different guns or are they all the same.?
They are all the same for pressure at a given temperature.... but the higher the temp. the more pressure....

Then the conclusion is that ALL co2 dependent air rifles probably have the same fps ...If thats not the case..then what determines a lower
or higher fps ? assuming that the barrels are all the same lenght....what is the highest fps that can be reached with a co2 cartrideg pellet rifle?
A number of factors; barrel length, valve/transfer port design, weight of pellet used to determine the velocity and so on (typically 68*F is used as the temperature for testing, but whose to say one manufacturer or another doesn't use 75*F to 'up' the numbers a bit- not saying this occurs, but I don't recall any manufacturer specifying the temperature they used for testing, and most do not publish the exact pellet weight used).
