FX 580cc Bottle Upgrade - How many more shots?

This is like asking how many more miles a bigger gas tank will give you. We need to know your "Mpg" or in this case how much air you use per shot. What's the approximate shot count you have now with a 480 or 500cc bottle?

I gotcha. Rather than calculating what I can gain, I just wanted to ask someone who has already upgraded and what their experiences were and go off of that.


For my .25 700mm 33.5gr slug at 970fps I get almost exactly 2 full mags so 56 shots.
 
Assuming your going From a 480cc 240bar to a 580cc 240bar then, an extra 100cc (20% ish) should give you around 20% more.

My thinking is to have a 580cc and a 480cc sitting in reserve, that is around 120% more

if I get 56 shots now then 20% more is about 11 more shots
