[QUOTE="Eaglet, post: 248120, member: 3756"] Gents, here are my two cents worth. This is how I understand it: Coriolis effect has two components, X and Y. X is a horizontal component and Y is a vertical component. The X component or [B]Horizontal component[/B] has to do with your Latitude, meaning how far you are above or below the equator. Right at the equator the horizontal effect is zero. At the poles you obtain the max. values. It goes from zero to max, from equator to a pole. The horizontal component has nothing to do with the direction you shoot. The Y Component or [B]Vertical Component[/B] has to do with the direcction you shoot or the Azimuth of the target as well as where you are on the earth. In the northern hemisphere when shooting easward you'll hit high and when shooting westward you'll hit low. Here how it looks in LoadBase: [IMG]http://i43.tinypic.com/21bna0x.jpg[/IMG] Here we are only concerned with Azimuth = 90° and Latitude 45° N. Now let's go to our shooting tab. [IMG]http://i44.tinypic.com/2dsl98k.jpg[/IMG] This screen does not show any corrections for Coriolis because the Coriolis box is off. When we turn it on, we will automatically see the numbers change for both, elevation and windage. [IMG]http://i41.tinypic.com/11llzxv.jpg[/IMG] Because shooting east you hit high, the program corroborates that by showing a lower come up when corrected. On this last screen-shot, it'll show you in inches the correction needed for x and y at 1200 yards. [IMG]http://i40.tinypic.com/2ptp8he.jpg[/IMG] Thanks for reading! [/QUOTE]
