I've seen pronghorn hit with high lung shots by bowhunters run a couple miles. I've seen pronghorn shot nicely through the lungs with Barnes bullets that didn't open travel a long damned ways. I've seen liver shot pronghorn go a long damned ways. I've seen gut shot pronghorn, and pronghorn with wounds to several extremities, keeping up with the herd, heading for science knows where.
Haven't been in on nearly as much elk killing, but have been in enough elk rodeos to know it's not something I want to repeat.
The wounded pronghorn were in open country, so they were often easier to find than a wounded elk. But that's an entirely different subject. Shoot something around the edges or blow a leg off and you're in for a rodeo. Put about any sort of decent bullet through the breathy/bleedy region, it's going to croak soon. This killing stuff just isn't that hard.
