I am using version 8.10 of the Nightforce Exbal program and shooting a 300 Win Mag at 3000 fps with a 180 gr. Accubond. Elevation= 800 ft. Temp= 50 RH= 50 Sight in distance= 200 yds. I am using standard atmosphere pressure At 675 yds it calls for 12.50 minutes. At 1025 yds it calls for 27.25 minutes. When shooting at the 675 yd target I am 3-4" high. When shooting at the 1025 yd target I am roughly 24" low and needed to correct the elevation to 31.00 minutes by trial and error. I tried to validate the trajectory at 675 with + 4" but then it calls for an even lower (26.00) elevation at 1025 yds. If I validate the trajectory at 1000 yds and say I am 24" low, it gives me a 29.75 elevation at 1025 which is closer but then the elevation for 675 is 13.75 which would even be higher. I am a little confused and not sure what would be the right thing to do to get both ranges right. What do you think?
