CO2 Vs HPA (High Pressure Air)
Palmer guns are designed to run off of any compressed gas.
CO2 is just a better gas in ideal conditions.
HPA expands faster than CO2. CO2 has better properties for launching the ball because it expands slower. When in colder temps, HPA properties stay more consistent, rather than loosing some of its expansion rate due to cold temps.
I myself play with CO2 as much as possible but if its too cold or or in a tourney Ill use HPA. Hot days are perfect for CO2, my tanks last forever on a Blazer! I also use the screw in HPA type preset to around 800 psi so I don't have to change my bottom line setup.
