After shooting a chrono today and getting an MV of 2676 with 168 A-Max out of a 308 20 inch barrel with ES of 8 I am having troubles matching my drops with this info. My 680 yrd hold (not dialing and the scope at 12 power as it should to get accurate MILs) is roughly 3.8 MILs and my 1120 is almost exactally 8. In order to get this data from a program I have to use a g7 bc of .975! I'm at 3190 elevation, temp was 24.9 C, pressure was 29.67, and humidity was 18.7. Any ideas where I am going wrong?
