I took wind-reading class on Sunday, which he held at American International Marksmanship Academy. There were a total of seven of us in the class. We started the day with short lecture on natural wind indicators for speed and direction followed by the math behind wind drift calculations. We then set up on the unknown-distance range where we alternated between spotting and shooting. The spotters practiced making wind calls with Shep while the shooters dialed adjustments and whacked steel targets from 400 to 800 yards.

I had printed a range card using JBM Ballisticsfor the Southwest Ammunition 175 SMK I was shooting, and the elevation proved exact within 0.1 or 0.2 mil for all the shots that day.

The Atlas bipod worked beautifully. The play in its hinges lets the rifle recoil backward without moving the feet. And the pan feature eased target acquisition and transitions across the width of the range. I credit it and some tweaks to my position learned from this video for letting me keep the crosshairs on target through the entire firing cycle and see my bullets hit the steel targets. No luck seeing vapor trails form my bullets, but I only saw one or two of them through my spotting scope that day.

We switched to the 12" x 24" target hanging at 1,000 yards with the light fading at the end of the day. An intervening rise that obscured the bottom half of the target added a degree of challenge. My first shot went high. I held low on the second and put it into the dirt in front of the target to check windage, which was perfect. I came down 0.2 mils of elevation and connected with eight of the next nine shots. It was very neat how the bullet took nearly two seconds to reach the target, and the sound then took another three seconds to reach the firing line.

The facilities at AIMA are still under construction as of today but looking very impressive. I’m looking forward to shooting and taking classes there in the future.
