00:17:07 | This is part of the Putting Rounds on Target DVD set. In this 17-minute segment, Bryan presents the nature of wind as well as the mechanism of wind deflection. There are many misconceptions out there about how bullets are deflected by the wind and how the wind is calculated. This segment sets the record straight. For example, it’s lag time and not total time of flight that’s proportional to wind deflection. Breaking wind into cross-wind and range-wind components is an important practical skill that you can use in the field to make quick wind corrections. Where the wind matters the most, vertical wind effects, and wind uncertainty effect on hit percentage are all covered in this video on perhaps the most challenging aspect of long-range shooting.
