[QUOTE="sdowney, post: 704134, member: 15618"] Assuming most of us are shooting in the northern hemisphere and using right hand twist barrels, how do you guys account for the above? From my research, I'm seeing anywhere from a .5 to 1.25 MOA drift right at 1000 yards. If you zero for say 300, do you add some left MOA to account for the longer ranges knowing the being an inch or two to the left at 300 probably isn't going to change much. I'm about to pick up my new custom 338 Norma Mag and was just curious about the effects of spin and coriolis at 1000-1500 yards. Thanks for your widsom. [/QUOTE]
