Sorry for the very late response.  I was just looking at old posts and saw this one.
You really shouldn’t see any difference between filling your gun with nitrogen or air.  They are actually almost the same. Air is a mixture of 80% nitrogen and 20% oxygen. So, when you fill with air, your really putting 80% nitrogen in the gun.
Temperature will always affect the pressure inside a cylinder. As the temperature rises, the pressure will rise and vise versa.

As far as POI being affected by temperature, this is because the air the pellet travels through, is at different densities with different temperatures and humidity.  The colder the air, the more dense (thick) it is.  Think of it like shooting your pellet through water one day, then oil the next day, just not as a dramatic difference.   Hope this helps a little.
