I stalked the solo buck through a ravine, and crested a hill to spy him in the valley below. At one point I was as close as 100 yards, but then a second buck and three does joined the scene and stirred things up. The intruding buck, although smaller than the big one, chased him away from the does. The buck I wanted trotted out to 280 yards and hesitated. For the second time that day, the buck I wanted was getting close to the boundary fence. If he crossed he would be untouchable. I slid my Hoyt bow to the side and rested my Nosler Professional .243 rifle on a stubby bush. The first 85-grain Partition bullet hit the buck solid in the chest. I sent a second one on the way a moment later that dropped him in the tall grass. The mature buck, shown here, has horns that are a touch over 14 inches tall, with good mass and fine prongs. I guessed the live weight at 150 pounds, big for a pronghorn buck anywhere. His horns scored 75 inches B&C.
