Muley First you need to own a rifle that will meet your needs. Next you need a bullet that will perform on long yardage for the animal you intend to hunt. And the most important, quality practice at and beyond the yardage you intend to shoot. Different positions, temperatures and wind conditions. When you can hit your target from 50 yards to 500 yards consistantly you are ready to try your luck. At yardages beyond 350 or 400 yards (depending on caliber and bullet) your biggest challange is to convert wind estimation into hold off.
