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.
What does "gauge" mean anyway? As used here gauge means the number of round lead balls the same diameter as the inside of the barrel (aka the bore) that it would take to weigh one pound. It takes 12 lead balls the same diameter as a 12 gauge barrel to weigh a pound. The smaller 20 gauge would require 20 balls of that barrel diameter. The larger bore 12 gauge would require 12 lead balls of the bore diameter to weigh one pound.
In general the number of pellets in a shotgun shell...
