[QUOTE="jdmecomber, post: 1320908, member: 94549"] Ok If I uncheck my (windage is zeroed) button again on AE I get the same 131 inches of drift from AE, it appears AB subtracts spindrift/Coriolis from its zero setting with the last example at 600 yards which brought it from 128.1 to 124.8 but if for some reason you are truly zeroed at a range your entire wind calculations can be wrong with AB because it doesn't have the option (windage is zeroed). I prefer AB so all I did to fix it was go into the wind factor setting and adjust it to match my zero at 300. by like .13 or something. I realize most people cant shoot a 1" group at 300 yards to get a farther zero but I can measure .4 or .5 inches at 300 for the spin drift and Coriolis. How can you adjust for Spin drift/Coriolis at 100 yards when its a 1/10th moa or .10 inches when your group is .30 inches. Almost impossible unless your shooting .05 inch groups. So I choose to zero farther if you can shoot well and have good conditions, I hope this makes sense [/QUOTE]
