I've heard many times that shooting 22lr at 100y is similar to shooting 400y with centerfire. Those keyboard snipers that post that likely haven't shot either. The drop may be similar but the wind effect on the POI is nowhere close. Wind affects centerfire much more horizontally whereas 22lr is of course horizonal but also more vertical than centerfire. The direction is determined if you have a right hand twist (most common) or left. At Koko Head shooting on the left, center, right side of the range changes your wind hold simply because of the berms and the lay of the land. It's challenging but a great leaning opportunity. If it was easy, everyone would shoot 200-20Xs
For my .308 and 6.5, shooting out to 600ish isn't that difficult. I haven't shot 22lr to 100 that much yet. I did notice the head/tail wind effects on 22lr seemed to be quite pronounced. I definitely notice the effects and differences in head/tail winds at day 400-600 at one friend's property that I shoot at occasionally. It switches regularly over the course of the day, even over the course of an hour.
I was trying to "feel" the wind, as well as watching other wind indicators down range. Luckily, there were a bunch of folks who had wind flags/streamers on their targets. I was also watching the mirage at times.
This is always discussed on the "forums". Which is more important wind at shooter, midway, at target? It's all important IMO and I have my theories. The key is you have to shoot in all wind conditions to learn it.
Yeah. I've been watching a lot of stuff from long range shooters, including F-Class, about the different indicators of wind at shooter, target, and in-between. Quite interesting theories. That as well as POI adjustments and bracketing wind calls. All super interesting, but like you said, all need experience in it. Can't learn by just reading/listening.
