[QUOTE="Eaglet, post: 273602, member: 3756"] [b]Re: LoadBase 3.0 with (Spin Drift) AWESOME![/b] Chris, I think your little squirrel is running alright. Mine stopped a while ago. :) You're right, the effects are accumulative. Spin drift is affected by the twist of the barrel, the properties of the atmosphere but has nothing to do with the rotation of the earth. Spin Drift will always displace the bullet to the right if it's a right twist barrel, regardless of the direction you're shooting. On the other hand, Coriolis Effect has to do with your Latitude and the direction you're shooting. Producing two components, a horizontal component and a vertical component as shown here. [IMG]http://i43.tinypic.com/ic8lcw.jpg[/IMG] The horizontal component has to do with your latitude and is not affected by the direction you shoot; the vertical component is affected by the direction you shoot and where you are on the earth. Vertical component is maximized at the equator and minimized to zero at the poles. There is, though, zero vertical deflection when shooting due North or due South. As you would know, you'd hit high when shooting east and low when shooting west just following the same reasoning you used. Man I hope we got this right!!! :D [/QUOTE]
