Hunt as late as possible, the antelope migrate in with weather. Hold out for a big one. You can hunt early as there are many resident pronghorn, but with time there gets to be significantly more. It is an easy hunt if you just want to shoot a lope, it can get challenging if you are looking for 80+, but very likely with a little patience you can find a very solid buck.
It is an easy hunt and as long as you can shoot 200 yards you are good to go.
