What's cool about this footage is the mirage, though, not necessarily the distance, caliber, etc. Look closely at the target and how the mirage distorts the edges of it. That mirage distorting that target means that we have wind.
Finding ways to use mirage to your advantage are good. Mirage is a quick way to determine wind direction at distance. We can see mirage in front of that target moving left-right, without a lot of visible vegetation out there to otherwise determine what winds are doing.
If we were to pan right FAR enough, we'll eventually see right to left mirage (the opposite direction). That intersect point, where the left-right (video) and right-left mirage converges, is the general direction the main winds are headed. If we do a 180-degree turn from that intersect point, it'll be the opposite. The mirage will be 'separating' instead of converging. That wind is coming towards us.
The value of this is helping us understand what the winds are doing at the TARGET, not just what they're doing at our position. We can also use this from covered shooting positions where we can't FEEL what the wind is doing.
