FX Bigger bottle, how many more shots?

[Gambler]

Hi, is there a formula that can tell me how many more shots ill get from changing to a 700cc bottle from 480?

If I get 25 shots now from 250 down to 150bar, Will i get around 37 or so?

Im also considering trying a dual bottle adapter from inpact on my crown, need to modify my stock no problem, but I dont know if there is any gun casings that Will fit dual bottles?

It all depends on your tune. Like on my LCS 30 cal tuned for high powr(soon to change to moderate levels for target shooting) the switch from a 580 to 700 gave me another mags worth of shots, for a total of three whole mags(17 per mag, 580 bottle got me 34 shots, 700 now gets me about 51-53 shots, shooting the 44.75 Haydes at 966 fps)

I plan on backing off the power to around 880-900 fps so I’m guessing I’ll be more now closer to 4.5 mags.

There is a formula where you input the numbers to get you a calculated answer on the pyramid Airguns website
