Depending on how fast you were filling the gun, you might have been seeing an increase on the gun gauge due to the increase in temperature. (ideal gas law)  Basically as the temp goes up as the pressure goes up unless you increase the volume, which you are not.  Are you filling nice and slow?  That is a good practice, especially to keep from stressing your guns air cylinder.
