When setting up the Kestrel app, the gun profile indicates that the zero range is in meters. Also, the single target has the zero in meters. If my range finder indicates target to be at 103 yards for zeroing, do I have to covert yards to meters before making any POA to POI adjustments? Are all Hornady 6.5 CM bullets considered 4DOF as opposed to G1 or G7? Thanks.
