How many shots will I get out of my tank?
There is an old rough formula for HPA and the number of shots you can expect to get from a fill, all numbers provided below are an approximation.
There are two numbers to take into account: the size of the HPA tank normally measured in CU and the pressure of the HPA tank 3000 / 4500 / 5000
3000 = 10
4500 = 15
5000 = 17
CU * PSI = shots per fill
So, a common HPA size is 38/4500 which translates to 38*15 = 570 shots per fill.
c02 tanks are a little more hit and miss, since c02 is affected by temperature. On a hot day you can expect to get more out of your c02 then on a cold day.
20oz c02 = 700 - 1000
16oz c02 = 480 - 800
12oz c02 = 360 - 600
9oz c02 = 270 - 450
3.5oz c02 = 105 - 175
All the above figures are absolute guesses as there are too many factors that contribute to marker efficiency and propellant usage.
