How much will my POI change or Harmonics differ if I add a different tank?

[Bramezy]

Have any of you that have changed out your tank for a different one seen a change in accuracy?
I ask as I imaging a different weight up there is going to change the harmonics thus affecting accuracy.
I want a larger tank but have my gun dialed in very good right now and am very hesitant to touch it as far as changing parts, even the tank.
Thanks

I changed to a 700cc tank on my RAW 25cal and it didn't change anything about POI. Just be sure if you change to a high pressure tank, your regulator will take the added pressure or (like I do) just fill to the pressure of the old tank.

I put a larger bottle on my RTI Compact and it made no difference in POI. Did the same on my Ghost and no change there either.

I went from a 300 to a 580 and didn't see poi on impact

Hey rsfrid,
How many shots do you get per fill?
About 110+

I never shoot down to reg pressure. I fill to 250 bar and shoot down to about 150-175 bar. Yeah one hundredish shots.
