Agreed. My longest shot was right at 250 and that's about where I draw the line. I usually say to each his own but that is so far beyond the norm for most people.
I wonder how many animals have died a slow and agonizing death from shots like that? To many probably.
The distance of a shot is not always and cannot always be directly related to ethical practice. I practice shooting my guns at 7,8, and 900 yards. It's all I do is practice, practice, practice. At 600 yards I can consistently hit a 6 inch plate over and over again. My shot on this deer felt ever so comfortable. That is how practice pays off. 9 out of 10 hunters should have never taken such a shot. I have never taken a shot at a deer that I did not drop within 20 yards of his hit. What is debatable was the positioning of the deer. It was facing me but my options were limited and I took the shot and I was successful.
