Stupid question about nitro

[tparkin]

I'm lookin to get more shots per fill. I have a 68/300 tank at a field that can barely fill to 3000. If i go to a larger tank size (ie- 88/4500) and only get a fill to 3000 psi,am i achieving anything?

if you go from a 68/3000 tank to a 68/4500 and fill it to
3000psi its still 3000psi

if you get a 88/45 or 88/3000 you are gaining more cubic inchs so you will get a few more shots out of the 88 then you would a 68
