No co2 tanks are sold full.
It all depends on the size of the tank. What size. 12 gram, 8oz, 12oz, 20oz or 24oz?
It just depends on the tank size, temperature, gun efficiency and how much you shoot.
Last I checked sports authority does not fill HPA tanks. If you are looking to get a tank filled though I would not suggest going to sports authority unless it is your only option. I used to work at one and the employees there really do not know what they are doing when filling tanks and you would be fortunate to get a half full tank when you walked out.
"H" is not a size for CO2 tanks
a HPA tank, every marker currently produced (and every marker that has been produced for a LONG time) that will work on CO2 will also be fine on HPA. the output pressure of a standard high pressure HPA tank is around 750-800 psi, and the output on your co2 tank is right around 800 so it is a direct swap, id recomend getting a 68/4500 HPA tank, it will give you about the same amount of shots as a 20oz CO2
A 50 pound CO2 tank typically weighs around 35-38 pounds when empty.
No, paintball co2 is much higher pressure.
In the area of $20-$40
A 50-pound steel CO2 tank typically weighs around 30 pounds when empty.
It depends on the tank size. the average 20 oz is about 800 shots.
