Too many variables to say any specific distance is fair or not. There are bucks and bulls that live most of their lives in oak brush covered hills and thick timber mountainsides where there might only be a few small open areas to get a shot from an opposite hill further than 500y away. Stomping up in their territory is loud and futile. If I spend multiple days waiting for an opportunity that probably won’t even happen anyway, I’d call that pretty fair chase.
On another note since this thread started with Matt Rinella stuff. He seems to have lost all the steam behind the hunt quietly movement. I recently saw one of his YT videos was a few days old with less than 30 views. I agree with a lot of what he says but he talks like he’s been stuck in a cabin too long.
