N2O pressure in a 10lb bottle?

[mean05]

i usually try and squeeze 12 lbs into my 10lb bottle. freezing the bottle usually helps get it there.

downfall to this is that first hit is hard to maintain the constant pressure....you will have it at 1200psi cool and by the end of the run its at 900 and cold...now you have to spend 10-15 min heating the bottle back up...if you just start out at 10lbs then your pressure drop wont be as severe and youll have a better pass and no lean to fat problem through the run
