First of all welcome to the forum! stick around and learn as much as you can as theres a lot of information here. I go to Wyoming every year for antelope but so far have not checked those units out. I have hunted many different ones by going over the data for draw odds and public land or HMA areas available. Hopefully someone with real information will jump in but that't all I have.
Good luck with your hunt if you make it up there. You will love hunting antelope if you haven't done it before already.
Welcome to the site. Alomst anywhere in Wyoming can be good for antelope. We have been going there for about 6 years now and we always do very well. I do not know much about 18 or 19, but I have a nice book at home that might have some info....I will check later tonight and let you know. If not I can give you some insight to some of the areas around where we hunt.
One of the things I struggle with when afield is keeping my rifle clean and in good working order. Small amounts of dust and dirt collect moisture; moisture can freeze rendering your action immovable when you need it most. I have seen this happen on multiple occasions, and over time, I’ve learned the cause and how to prevent this from happening.
The first thing that you need to avoid before going afield is leaving excess oil on the gun. Oil will trap dirt and sand in all the wrong places....
