Factor this in gents . . . hunting out west is far different than sittin' in a tree stand in Georgia or Indiana. Unbelievably different. We can't bait or use feeders (even game attracting crops), we can't hunt during the rut, we are scouting/hunting/covering 1000's of square miles to your "40 acre woods" . . . just to mention a few.
You have to practice 300+ yard shots in the unlikely event that it is your only "shot" at that prize. No self respecting hunter takes unethical shots. Please don't think this is common place. Hunting is still the sport of finding game and putting the stalk on them. Those shows or video better say "Don't try this at home" at some point because it is not common to have to do that, but exciting as hell when it works!
It's one thing too to lob 100 yard shots at yotes or prarie dogs or the neighbor's dog (oops!), it's wuite another to try it on an elk, mulie, or whatever.
Again I emphasize . . . those guys have highly sophisticated equipment (who even owns a range finder that goes that far?), and have practiced it many, many times.
