Default nitro shots per tank

Now i have a seen the formulas for figuring out shots per tank on average 10x ci for 3000 tanks. I even have a web site that lists the verage shots per fill on tanks. But what i would like to know is what is an average paintball marker nowadays. I mean a spyder running 800 psi or an ion running what 140ish. or is there a real diffference in efficinecy(sp?) between most stock markers. Going low pressure on a spyder definitley gets more shots per tank. what about all these low pressure markers that come stock lp?

Ok now the reason for this post. I belive it was hossy that pointed a link out to firstcallpaintball for a 72/3000 tank and 1000 rounds of black box spyder paint for 75 dollars. t the ad says you will get 900-1000 shots out fo this tank. but the equation says somethign diferent. I need atleast 900-1000 shots to go hpa for a small day of paintball. the weight is not a factor for me but shots per tank is.

{edit} only read the top of your post, went and fully read it and realized this has no relavancy to what your asking, oh well, it was a lot of typing so im going to leave it up!

some of the reason that being an lp marker can be beneficial if how deep you can shoot into a tank. if you think about it, a Mag which needs ~700psi to operate can only use an air fill down to that 700psi before needing a fill. Whereas an ion or other LP marker that operates ~200 psi can shoot a fill down to that 200psi, effectively getting more shouts out of that tank. so assuming both guns have the same efficiency the LP gun will get more shots due to the fact it can operate at a lower pressure.

It will differ depending on the gun being used but 72/3000 will get about the same as 20 oz CO2 bottle.

68/45 and your problems are solved, maybe you can find one cheap on ebay or th BST thread somewhere.

I wouldn't push it and chance running out of air in a game, that would suck. This is the primary reason I have kept to co2 for the most part, because I can't get HPA fills where I play.

Yes, the stock LP markers from Spyder are already made efficient. It's the easiest way to go IMO if you want an efficient Spyder. Otherwise, you'll be going through a lot of work to make it LP.


Simple way to find your shots per tank (besides just going out with a case and seeing physically):

72 Cubic Inches
X 3,000 pounds per square inch
216,000 psi total in tank

You then take this number and divide it by how many PSI per shot your marker averages. This, mind you, is not the OP of the marker. It is what it uses of what you put into it. To find this out, you need to find out how much paint you use for a set amount of PSI in your tank. I.E., let's say you use the 72/3k until you're down to 1,500psi and got 500 shots from it:

72CI
X 1,500psi
108,000psi used from tank

108,000psi / 500 shots = 216psi per shot.

To go from this to the estimate of your total tank's shots, you then take that number and divide it into the total PSI of the tank:

216,000psi / 216psi = 1,000 shots per tank.

Keep in mind this is an estimated number, and varying conditions will cause you to either meet or exceed this number. This is also an example, and not what you will get. If this is confusing (most likely is to everyone else but me!), let me know what you need explained further.
