Interesting that we don't hear the boo/boo's of "short range" hunters....... Or bow hunters.
It is. I have a longbow and recall reading an article by one of the most respected traditional bowhunters out there. His standard for effective range and accuracy (if I recall correctly and I'm pretty sure I do) was that a trad bowhunter should be able to put 8 out of 10 arrows into a target the size of the vitals of a deer at his maximum range.
And IMHO, making a good hit with a traditional bow, no sights, finger release, and so on is just as complicated (if not moreso) with just as many variables or things that can go wrong as as a long-range shot with a scoped modern rifle.
Somehow 20% is an acceptable failure rate in that case, but not for long-range rifles.
