I will admit that judging distances over plowed fields or over winter wheat is difficult. I can only assume that estimating range over open prairies is also difficult.
That is very difficult. The way I approach it is to estimate the distance of something further away than the object of interest. Maybe a tree line or windmill or whatever. Then estimate the distance to the object relative to the major feature distance.
For ml hunting it's not much of a problem since things at 100 yards or less are not that difficult.
Two years ago I shot an antelope at 280 yards with near perfect shot placement (not ml). Shot was off crossticks and had figured it to be 270 yards. I took a long long time to decide on that shot. Not in calculating distance, but just sorta feeling it as well as looking all around at other features both nearer and further than the antelope. It's sorta thinking without thinking if ya know what I mean.
