As the liquid expands to gas in the magazine it results in cooling.. the cooler the magazine the less the gas expands.. resulting in a pressure drop inside the magazine.
the faster you shoot the greater the cool-down effect.
all guns that fire from gas in the mag suffer from this.
The specific properties of the magazine and the demands for gas of the gun can have a effect on this. Smaller magazines will suffer more than larger ones.
Ambient temperature also has an effect .. when it is 30c out you don't have many issues with this.. if you are trying to shoot below 10c .. you will have huge issues.
turn back to you highschool Chemistry.. properties of gas expansion are dependent on the temperature and the surface of expansion.
shoot semi.. or short 3-4 round bursts .. and you should be ok.
