[QUOTE="Bravo 4, post: 1350901, member: 8873"] Coriolis/Eotvos effect? Do you factor in latitude and azimuth to target? This may have a little to do with it. But what I found when shooting my .408 out past 1500/2000/2400 yards was that I needed to use a stepped BC to make things line up. I had to figure this out on my own as the manufacturer only had a set BC number. From certain yardage to yardage .xxx BC worked, then it dropped to .xxx. This worked in three different states at three different altitudes and three different environments. [/QUOTE]
