Who set the ethics in regards to proper shot distances? Can you show me where that's been written in stone? More things can go wrong at 27 yards than at 21, so should we stop at 24 then and just split the risk down the middle?
In my experience, traditional bowhunters wound deer at a higher rate than compound hunters. Not a fact, just how it relates to me through my experiences. They have shorter effective ranges and by your logic, should always be more effective than a compound past this "unwritten" ethical distance. However shit happens regardless of the weapon and/or distance. If I had to pick what caused more wounded deer based on my experience, sticks shooting sticks or compound shots past whatever this ethical distance has been defined as, traditional hunters would be in trouble.
You're a regular Howard Hill, so I know you're skewing the results. But I bet even you know more people who've wounded deer with a stick bow at CLOSE range than people who've wounded deer past whatever distance you deem acceptable. I don't see us long range unethical hunters calling for a ban on sticks.
