Gent's This is my first foray into scope dialing, so please go easy on me. Anyway, I just installed a Nightforce SHV on my Tikka T3X 6.5 Creedmoor. After getting it sighted in, zeroing at 100, verifying accuracy and velocity of my pet load(147 ELD-M), I plugged the data into my Ballistic App. Initially, it appeared to be spot on, as my elevation impact was right on the money at 200,300 and 400 yards. When I dialed for 500 though, the bullets were impacting about 6-7 inches high? Any idea why this happend? I feel like all my inputs are correct, especially since drops at 2,3 and 400 yds were right on the money. Thanks all. Any input would be greatly appreciated.
