Sorry, that's 2.0 MOA at 50 yards and 4.0 MOA at 100 yards for a 10 MPH full value (90*) cross wind. These were calculated from ballistic coefficient data supplied by Lapua. Using the angles that Rutty noted, a solution can be estimated for various wind speeds in various directions. Most smallbore s...
