[QUOTE="adam, post: 2591611, member: 9382"] That worked for me on several rifles. Once I get a good group at 100 I move out to 7-800 and shoot a rock wall with book BC and a good estimate of the speed. (buddy accidentally center punched the crony) We used a good camcorder and a 7" display from amazon to refine the point of impact. I then use the shooter app and adjust the velocity until my drop matches. Several Rifles later I feel confident the drops match very closely. At 5000 feet we stoned a cold bore 1515 shot on a 7" target with a 6.5 creedmoor using factory 140 ELD's. Also shot the mile successfully with the magnum. Drops were right on across many days. Oh the wind, if only for the wind!! [/QUOTE]
