You can expect approximately 620 shots from the tank you mentioned. A rough way to figure how many shots per tank is to multiply the cubic inches of 3k psi tanks X 10 and 4.5k psi tanks by 15. Typically, you will get more shots per tank out of a comparably sized CO2 tank than you will out of HPA.

Wait, my mind must be a little foggy on this topic but wont a player get more shots out of a Hpa tank than a C02 tank? I thought that was one of the beneifts of upgrading. Or was it just a more consistent air flow from the tank? Man, how the mind forgets things, the more you cram in it.

The big advantage for compressed air is the consistency.  HPA has this advantage because it does not change states based on temperature.  (I.e. liquid or gaseous form.)  This temperature sensitive change of state is why a CO2 tank can store more potential energy (in liquid form) in a tank of the same dimensions that would hold many less potential shots if it was HPA.  (In warm weather--in cold weather the use of CO2 becomes problematic.)

As Mack said, it really depends on the weather conditions. On really warm days, I had times when I could get close to 1/2 case of paint on one 20oz tank. On colder days I was having to refilll after shooting only a couple of hoppers. The variable rate of expansion is one of the reasons it is hard to give an approximation on shots per tank with CO2. Which brings up another bonus of HPA over CO2. HPA tanks have guages that tell you pretty precisely how much air you have left in the tank. You look down, read the guage and know essentially how much you have left. This can be an advantage in longer all day games where you may be out on the field for an extended period of time. Knowing that you are down to 1500psi will allow you to adapt the way you play to accomodate the air you have left.  With CO2 it is a guessing game. I can't tell you how many times I have heard guys with CO2 getting the fart of death on the field as they are in the middle of mounting a charge. It's a bit funny to watch them get all pumped up, charge your postion, only to have their marker putter out as they cuss and stare at it like it just crapped in their hand. Then to add insult to injury, they get lit up.

I use CO2 on most of my markers because most of them are (older) Tippmanns and they seem to work better on it.  I never get the "fart of death" because I have each tank labeled with its empty weight and check them with a fish scale before I go on the field and between games when I know they should be getting low.  Once they get down to around six ounces I usually switch tanks and use the less full tanks for working on/testing markers until they get to the point where its time to refill them.

^^^^ Unfortunately or fortunately, you are not the typical player.

So an interesting thing happened a few minutes ago. I took out my Crossfire HPA tank yesterday to fire off my new Tippmann A5. The tank had around 2000 psi remaining when I finished. Today, I hear what sounds like a loud pop followed by hissing. I rack my brain to figure out what this might noise might be and it hits me, my HPA tank. I go to the room where the hissing is still occurring and yes, it is indeed the tank. It has miraculously sprung a leak. Because it emptied rapidly, just a CO2 tank does, it became cold, and frosted over. Is this normal and is it relatively normal for an HPA tank to burst? (By burst I mean spring a leak.)

Thank in advance. Please keep in mind the tank was only filled once and it has sat in storage for nearly a year.

Where is the leak coming from? Sounds like a burst disc let loose. I've had it happen on a CO2 tank before, but not on an HPA tank. At least not on a fixed reg tank.

Yes, I believe it was the burst disc. It wasnt the pressure gauge or the air inlet. I assume the other two brass hexigon screws are the burst discs.

I am also guessing that only an airsmith can repair...
:(

Nope, any good paintball store will have replacement ones. Simply unscrew and replace them. Most paintball shops will do it for just the cost of the burst disc when they refill your tank.

Interesting enough I fund that get more than 720 shotsout of my72/3k tank with my phenom while I average about 700 out my new a5.

You should get considerably more than that from the Phenom considering it is low pressure.

I only carry 4 140 rd pods and the low profile hopper. So 760 rds is all i carry on me to the field. Add another 30 rds in TPX mags.

I am getting the TechT MRT Bolt Bad Karma Edition. Maybee when it comes in I'll do a actuall shots per tank count on both bolts.

I guess I should have highlighted the "should" part of that statement. I think I remember seeing where someone posted the approx shot per tank increase and it wasnt very significant. Considering the Phenom operates at IIRC about 1/2 the pressure that a normal X7 operated at, I would have expected a significant increase in shots per tank. I suspect, it may have something to do with the cyclone still needing to be powered.
