I'm planning on going to WY myself as a newbe, so can't give an expert advice but this is what I'm doing. Goto the WY fish and game site, there's tons of info on success rates, license draw results, ect. Get maps of the public land available to hunt on and ask WY F&G about private access (doesn't help to draw a tag and have no place to use it). Read all you can about the animal and hunting it. Ask questions to people that have experience in hunting pronghorn and the area (years of experience and great people here ). Good luck and keep us all posted.
The Utah draw is open now. Nonresidents can put in for every species now. Put in for the Plateau antelope hunt and you won't go wrong. Fun hunt with lots of antelope. Email me if you have any questions.
Northwest Colorado is Famous for big prairie goats so i would guess Southwest Wyoming would be the same since its right there! I hunted close to Cheyene saw lots of animals and easier stalking because of lots of small fingers and troughs but it was on a private ranch that was open for the public through wyoming game commision but that area has become strictly private now.
If you have severial days to hunt dont be in a hurry to shoot one. Prong horn are more fun to watch than shoot and you'll learn a lot. Bucks are very territorial and will patrol there turf,if you blow one out that has does and there isn't a lot of hunting pressure he will be back in the same area the next day. Young bucks are shamless and will try to steel any other bucks women,it's a hoot to watch.Depending on how deep in rut they are I'v had bucks confront my truck when I entered there area but ofcourse they knew I had a doe tag, funny how they sense that! When you get one get it skined out and in a cooler on ice FAST they dont last long at all in september heat on the plains.Have fun and good luck
If you have time,scout for a good buck. There are lots of good ones out there. You better have some good optics, as you will be looking through them often. Use the terrain to your advantage. When you come around bluffs or hills or top them, do so slowly. Antelope can detect unusual movements from a long ways off. Thier sense of smell works for them too. Don't be surprised if you have to crawl for quite a ways to get within shooting distance. It would serve you well to practice shooting in the wind. Thats just something that is normal here. If you know someone with a ballistics program, make a card with drop and wind drift. My last buck was in the corner of a walk in area in the open with about 15 does. I had to crawl about 300 yards, after I got down wind from them, to get within my self-imposed 400 yard limit. Occasionally I had to stop when the does were looking around.
Over the years I have seen several elk and deer hides left in the woods by hunters and I have to wonder why they do this? I fully understand and agree about getting the hide off the animal as soon as possible to cool the meat, but why not pack out the hide with you and use it? As far as I know there are no state laws that require you to take the hide home, but to me why waste such a beautiful part of the animal? Some might think they have no use for the hide or it costs too much to tan....
