[QUOTE="cdixon1, post: 2931177, member: 91071"] I had my first chance to shoot some long distance this year, but the drops I am getting from ABMobile (and my Fury 5000AB) start deviating from my actual drops past 600 yards (450 and 505 was first round impacts using AB data). I had an experience spotter who help walk me on target to get my actual come ups. Using those, I was able to make consistent hits at all ranges on a 12 inch plate. Can anyone spot an issue with my input data? Anyway to explain why the 695, 860, and 1001 actual adjustments are so far off? Any thoughts on where to look/what to do next? It certainly could be me being a newb, but I just want to make sure nothing jumped out at the more experienced shooters. I am going to try to get back out and confirm again, just haven't had time yet. 7saum 2912 velocity (magnetospeed) 175 Berger Elite Hunter (.336 G7) Scope Height 1.3 Zero 1" high at 100 Elv 2650 Station/Absolute Pressure 27.95 (from nearest airport) Temp 60 degrees [TABLE] [TR] [TD]Yardage[/TD] [TD]AB Drop (MOA)[/TD] [TD]Actual (MOA)[/TD] [/TR] [TR] [TD]450[/TD] [TD]5.6[/TD] [TD]5.6[/TD] [/TR] [TR] [TD]505[/TD] [TD]7.0[/TD] [TD]7.0[/TD] [/TR] [TR] [TD]695[/TD] [TD]12.5[/TD] [TD]11.0[/TD] [/TR] [TR] [TD]860[/TD] [TD]17.9[/TD] [TD]15.5[/TD] [/TR] [TR] [TD]1001[/TD] [TD]23.1[/TD] [TD]21.5[/TD] [/TR] [/TABLE] I certainly appreciate any input, and thank you for your time.
