The pronghorn, with its large eyes (think of a 1,000X scope, a guide once told me) and fleet feet, is uniquely equipped to evade predators. As a result, many hunters think success depends on the ability to make 300- to 400-yard shots. Most of these attempts, though, are desperate Hail Marys. The better way is to stalk close enough for the more makeable 150-yard shot. You don’t need a lot of gun—in this case, think .25/06, .243, or .270.
