Re: Nightforce Ballistic Targeting Software By Ward W. Brien
I finally figured out how to get Ballistic much closer to JBM...at least so that a trajectory for my .308 is very close out to 1100 yards. You have to turn off the Zero Atmosphere, then set the Current Atmosphere so that temp, humidity, and altitude are the same as JBM. Provided you are using 29.92 as the value in JBM and have checked "Pressure is Corrected", you then set "Standardize Pressure" off in Ballistic and use 29.92 as the Barometric Pressure. Seems totally bass ackwards, but it does match that way.
