Can anyone help me with a crude rule of thumb 'formula' for doping wind as taught by the Army in the late '60's? I can't remember whether it was in basic training or ROTC, (I went thru both), but the gist was, with your m-14 sight on 'battlesight zero'...to calculate for full value wind correction, you grabbed a handful of dirt, grass, or leaves and released them at shoulder height, 90 deg from line of fire, pointed your extended arm at their approximate landing spot. Then, you estimated the angle formed from vertical to your arm, here's where it gets real shaky, divided by ten? And used the result to take your clicks into the wind. Example, wind is from right to left, you release the debris at shoulder height, it blows and lands at roughly 30 deg to your left, divide by ten gets you three...put 3 clicks right windage and you're supposed to be in the ballpark. Does anyone remember this stuff? Or care? We all promptly forgot it and Kentuckied the wind. I'm thinkin' with slower cast bullets a guy could interpolate something useful...since I personally feel something of the historical rifle experience is lost with anemometers and mini computers.
