CO2 Fills         9 oz thur 16 oz $4.00

                       17 oz thru 20 oz $5.00

                       21 oz thru 24 oz $6.00

The number of shots you can get out of a CO2 bottle typically depends on two things: the gas efficiency of the valve in your paintball gun, and the temperature during play.

Most stock paintball guns have the same gas efficiency so that playing temperature has more of an impact on CO2 usage. At room temperature you can expect:

9 oz: 350 shots

12 oz: 500 shots

16 oz: 700 shots

20 oz: 900 shots

HPA $5.00 a fill or $10.00 all day air

These bottles hold compressed air and offer more consistency from shot to shot. As your CO2 tank becomes empty, the paintballs' velocity will drop, costing you range and accuracy. HP bottles avoid this, as well as provide more consistency during extreme temperatures.

In the sport of paintball, Nitro, High Pressure, and Compressed Air all refer to the same thing.

Capacity: High Pressure (HP) bottles come in different capacities and maximum filling pressure. The capacity is stated in cubic inches (ci) and the maximum filling pressure in pounds per square inch (psi). The higher the capacity the more shots you will get from a bottle.

Bottle Construction: Because of the high pressures the bottle has to hold, the basic bottles are made of steel. In an effort to make the bottle lighter but just as strong, there are bottles made of aluminum wrapped by carbon fiber. These wrapped bottles are lighter but more expensive than steel bottles.
