MY ballistics that I listed were, 50 yard zero , with 2 inch bore height. Those where the numbers I posted. 0 at 50 yards is usually 1 inch high at 100 yards. I do the = 50 yard zero because I use a 55 gallon sand trap to recover and measure my bullets weight SO I sight in at 50 yards. Nightforce Exbal is what I ran the number AND posted them by.
