[QUOTE="JCow14, post: 1710635, member: 110470"] Coriolis will come into effect shooting north or south, but has a horizontal effect instead of vertical. Pair this with a right hand twist barrel/ spin drift in the northern hemisphere say North Alaska or Canada and you have a POI shift right- big time. I always went by [U]Horizontal correction[/U] Northern Hemisphere POI right+ spin drift (right hand twist barrel) Southern Hemisphere POI left [I]Poles max deflection Equator zero deflection [/I] [U]Vertical Correction[/U] Shooting East POI high Shooting West POI low [I]Poles zero defection Equator max deflection[/I] [/QUOTE]
