Took my FNAR out to the range today. Gusty cross winds from 5-20, periodically snowing so hard I couldn't hardly make out my target at times.
I shot some groups, was easy to read the wind when the snow was falling, but it was coming it spurts. During the periods the snow stopped, I had no wind markers whatsoever. All the vegetation was either frozen to the ground or just stalks with no foliage, and not moving.
I was shooting 6" circular shoot n' sees with no backing, so if I misjudged the wind AT ALL, I was off target completely. With 168 grain 308 matchkings launched at 2650 fps, 5mph crosswind gives 3.59" of drift, while 20mph gives a whopping 14.36". Complicating this was a cut in the hill about midway to the target, which caused the wind to channel up, and give a slight updraft.
On a fair day, I can put together 1.5" groups with this rifle at 300 yards all day long. But today the drift spread was not just bad with the horizontal component, but that updraft drove me NUTS.
Overall, it was also a very humbling experience. When it was snowing, and I had a wind indicator, I was able to put all of my rounds on target (and a lot of those went in the X ring). But during the periods when the snow stopped, I missed the majority of my shots completely!
It was frustrating the hell out of me. I couldn't find a wind marker to save my backside. I was shooting from shelter and couldn't feel the wind, but there weren't any apparent visual markers I could key on. (I never shoot with flags.)
Today was some of the most difficult shooting I've ever done.
I need to get out more in foul conditions like today. It's really challenging!!! It also reminded me that the human component and trigger time is much more important than squeezing that last little .02 MOA out of a handload.
Think I'm going to skip benchrest shooting this year and just pick the nastiest, ugliest, crappiest days I can find to go shooting. I've hit the limit of what I will ever do on nice, calm days. I need more practice with crappy, real world conditions. Not more practice with squeezing another half inch off a group.
