25/50 MAX rule for us
25 yds traditional
50 yds compound
20/40 is actually better. I personally prefer slam dunks (under 20 yds) to half court shots.
Truth be known, anything past that distance the missed/wounding rate soars.
Archer accuracy is not the entire issue.
The arrow is just in the air too long no matter how accurate the shooter. Anything over 0.4-0.5 seconds of arrow flight from release to impact has a much greater chance for a problem. Half second is an eternity when it comes to arrow flight and animal movement.
(example: 300fps compound bow+50yd shot=0.5 seconds of arrow flight)
A foam target has never taken a step at the release.
