Wow, I know its only a couple of clicks at either end ranges but might as well get it right. I spent a few hours last night just searching for the Mk3 settings & found them stating 1/8" MoA & then the others 1/8" at 100 yards,..............odd!!!!!!
Good advise calibrating the turret based on two shots with a complete turret turn between them to get it spot on, just need to find 55 yards indoors & a gun vice, as I will never get a wind free day where I shoot!
Thanks for all the clarification so far!
