less C02 than if the tank was warm.
Velocity Spikes: If you are shooting a regular (gas) C02 tank and
you point the gun downward, you will notice frost coming out
of your barrel. With some guns (Automag, Autococker, etc.) you
will quickly render your gun unusable if this happens. If liquid
C02 gets into your gun's valve, you will usually get velocity
spikes. Let's take a look at why this happens. The liquid and gas
C02 in your tank is always the exact same pressure because your
tank is a "closed system". The pressure in your gun's valve will
also be the same pressure. The exception to this rule is if you are
using a pressure regulator on your gun. When liquid gets into
the gun valve, your velocity will spike because you are hitting
the paintball with more C02. In other words, the C02 in the
valve is of a much greater weight than if it were in a gaseous

2. C02 works fine for paintball guns, but if you're looking for
high performance, you may want to look at purchasing a high
pressure system.
About high pressure (nitrogen and compressed air)
When someone refers to high pressure in regards to paintball,
they generally are speaking about nitrogen or compressed air.
For Paintball purposes both are
C02 quickly. Your tank
gets cold because the liq-
uid C02 inside is chang-
ing into gas to replace
the C02 used during
rapid firing. This change
from liquid to gas is
called a change of phase.
the same. A high pressure system can be filled with
either nitrogen from a bulk tank, or compressed air
from a compressor or a scuba tank that was filled
from a compressor. The reason these systems are
called high pressure systems is that they are filled (by
pressure, not by weight as with C02) to 3000 - 4500
600-800 psi outgoing pressure. This means that a
constant pressure flow to your gun can be safely
achieved.
The advantages of high pressure: Nitrogen and
compressed air have virtually the same
characteristics. Compressed air is the air that you
breath every day that is compressed into a higher
pressure than its normal state. Compressed air is
around 78% nitrogen and 21% oxygen. Under
normal conditions, nitrogen and compressed air are
unaffected by temperature changes and fluctuations.
Unlike C02 which boils at about 89 degrees
Fahrenheit, nitrogen boils at the very high
temperature of 196 degrees Celsius.
So for paintball, no matter how hot or cold it gets the
gun will be supplied with consistent pressure from the
regulated tank (a ssuming your equipment is working
properly). This means that your velocity will stay
much more consistent than you've come to expect
appealing to Paintball players than C02. Another
advantage with high pressure is that you do not have
you don't have to chill the tank to fill it. To get a
complete fill however, you need to fill to 3000 psi,
wait a few minutes for the tank pressure to stabilize,
