Forget about shooting to 500 yds. Use good hunting skills and close the distance where you can "hold on hair" and make the shot. I believe alot of this distance shooting at game is more that guys think they can while it's usually a situation where the distance can be closed if they tried. It's called hunting and not just shooting. I've taken 4 North American wild sheep, Slam of caribou, moose and lord knows how many elk, deer, antelope, etc. along with other game on 3 Continents. Never with a range finding reticle. I only mention my success not to boost but as a testimony from one who has done it. Leave the ultra long range stuff for targets and the steel. Practice better hunting skills for a high percentage shot and a clean kill. We owe it to the game we pursue.
