[QUOTE="Shane G., post: 398689, member: 24782"] I've had the same happen my scope was not accurate supposedly 1/8"@100 but when rotating 1 full turn it was 10.5 higher,1 turn was 60 clicks so it figured out to .175"@100. I got a drop chart for my loads and was shooting at 620yrd. dialed up and was way high had to drop all the way back to where i had it marked for 550,next day after returning to zero it was on @100 go back to 620 and my dial up from the day before was not even close again. Seemed like even though it would return right back to zero somewhere on the way rotating up it was going off and not consistant. Also on your calculations your scope centerline to bore measurement will make a difference too. [/QUOTE]
