what should my bottle pressure be at when i get it filled if its around room temp 60-70 ..

and what about half empty?
my ***** sittin at 600 psi and i already shot a bunch of times
i have a 10 pound bottle and just got a gauge

 

900-1050 id optimal for spraying

 

600 psi at room temp is normal. You want it around 1000psi for the best hit. Also in my experience if you have 3 pounds and under, even though its 1000 psi it just doesn't hit as hard.

 

850 psi atleast but would not reccomend over 1100 invest ina heater if u dont have one

 

Yeah, I second the bottle heater idea... just make sure that you get a pressure safety switch that turns the heater OFF if the bottle temp gets too high, or else bad things can happen!!!
