Pronghorn hunting is one of my favorites. I waited 13 years for a buck tag in the unit I wanted. Pretty much got screwed up by road hunters blasting away. I still got a nice buck, waited until the slob hunters had stopped the pot shots and they calmed down a bit. 680 yards (my furthest) and a good bit of breakfast sausage in the freezer.
I have found that there are some areas where they don't seem to jump fences, and others where they mostly do jump fences. The morning/evening watering holes, and having them scouted better than the others, are the best bets. They are curious too... I have had herds walk up on me within 30 yards while I was field dressing their cousin. I had a nice buck follow me for about 800 yards. When hunting bucks, patience is hard since you see so many. I passed at least 6 this year before I shot, one I stalked to 80 yards. I could tell good stories about Pronghorn hunting for a page or two, but that is part of the joy of hunting them, the stories. Ususally hunt them with the .243, this year, the .260, but I have taken two with a .40 Super and one with a .414 Supermag as well.
