Re: Dailing in the scope for wind
I use some type of stadia along the horizontal axis-- plex post tip, dot, whatever. Once i know it's MOA value, i simply apply it like the mil-dot guys do for wind reference as long as it's subtension is adequate for that use. My latest project is a very long-range handgun system that has the plex reticle in the 36X Leupold BR scope that's been converted to long eye relief. The problem here is that the plex post tip is only .75 MOA. That doesn't offer much for reference in the optic. This scope will have to be sent off to Wally Siebert in WA for 3,6, and 9 MOA dots, to reference wind at long-range. Besides that with only 38 MOA of windage adjustment ideally, this scope has very limited windage flexibility-- but it's the only option for very long-range shooting with a heavy recoiling handgun.
I use a weather watch to approximate wind holdoff that has an anemometer in it-- speedtech.com. Sometimes i use it directly, which helps me to get a feel for wind speed when i don't have time to use it.
