The standard CDS dial is in MOA. Get on Hornady.com and use their calculator. Print out a ballistic table with your load info and use the MOA column. Range your target, twist the knob to match up to the chart and shoot.

I have owned several CDS scopes and all have worked as advertised. Enjoy your new scope.

A true sportsman counts his achievements in proportion to the effort involved and fairness of the sport. - S. Pope
