While this topic may seem to be never ending, we do have new archers every year wondering what others do. Distance to me is an ethics question. Everyone has their own set of ethics about things which aren't written as law( within larger societal norms). Raising my two sons, I instilled (tried too at least) in them my thoughts on this topic.
Here's my

on it. Respect the animal, avoid wounding it, or worse, killing it over the coarse of several days. Be sure of your abilities and finally, ask yourself, if I hit it and can't find it, am I willing to eat my tag.
Tried to get them to create their own max distance with some guidelines.
