RE: 103yd with Bow & Arrow in the wind??
Well it was Ben Pearson so probably not many. And they didn't have the filming equipment like we have now days. Most of those old films are pretty much how it happened.
My father is one of the legends. But he didn't take bad shots. He knew his ability. And made some great shots on animals out to 70 yards. If things weren't right due to conditions or whatever. He didn't shoot. These guys had respect for the animal. They also may have been a lot better then most of us when it comes to archery and hunting. And they did it with a recurve.
I do agree with you ethical statement though. But someone had to try it sooner or later to start the learning process on what's a good shot and what isn't. These guys didn't have the resources like we do now days.
