The number of shots provided per tank is really dependent on the tanks size. I am the captain of the Bullit Paintball team, and I usually use a 20oz tank. With my 20oz I will get anywhere between 800-1000 shots, depending how fast I shoot. I would say that you'll usually get around 500 shots, and a max of 600 shots with your 12oz.
I have a spider sonix,and I can shoot probably about 1000 before it gets low
in determining this you must know A 12oz tank is not very large and Tippmann guns are not very efficient with air. You should expect around 500-600 shots. This depends on good weather conditions and the type of paint.
It depends on the size.
Around half a case (1000 rounds.)
A 20oz co2 tank will on average shoot about 1000 shots. This will vary if you have a response trigger, cyclone feed or regulator on your gun.
A Tippmann 98 custom 20oz co2 tank shoots 1100 paintballs
When using CO2 there is no set number of shots due to the spiratic nature when releasing the CO2 from the tank. CO2 is unreliable in the fact that the psi of the shots are not consistent and tend to waver and vary depending on temperature. However estimates can be made from the size and past records. 12g- 30-35 9oz- 300-500 12oz- 700-900 20 oz- 800-1000 24 oz. 1000-1100
If it is a good fill, you can expect an average of 500 - 700 shots depending on your marker.
about 500-600 depending on the gun
This can vary. CO2 itself is not very consistent, and the type of marker you are using will have an effect on this. Usually you can expect around 200-250 shots.
