I did address how I justify such shots. I said that those I know who seek shots that you and I would consider long range do so after much practice and knowing their limitations. As a matter of fact, they likely know their limitations better than I do because they shoot a lot more than me.
I'd love to get to the point where my limitations were increased due to practice and a rifle built for long range hunting. I'll take a 600+ yard shot on game when I've been clanging steel with regularity and encountered conditions similar to those in the field, I'll go ahead and take something at what may be considered "long range".
Problem is, you said yourself that you don't know things for certain, and then turned around and said that you DO know for certain that no one ought to take the shots you're arguing against.
