The volume of shooters taking less-than-long-range shots is certainly many times higher, and therefore the volume of "close-range" hunters taking shots they shouldnt is definitely higher"I don't think that's the meaning of that statement, I think it's that there are way more shitty shooters out there taking shots at "acceptable" ranges and still messing them up, as there are more prepared shooters taking longer shots.
But to say that a higher percentage of long-range hunters are more prepared to take long shots is a bit of a stretch. Maybe they think theyre prepared. But I would argue that high end equipment and "hitting steel" at long range gives far too many hunters unfounded confidence in their abilities.
