U H is right on the money, I would do CO, WY, MT and get over the counter if you luck out on all the above, can get pricey to apply for all the western states and they like to sit on your money for most of the summer
Colorado during 3rd rifle can be a pretty wild hunt. My first time I hunted with some experienced guys, and they told me to keep my rifle "unloaded". Bucks were everywhere, and we spent a lot of time field judging at distance. Muley's look pretty big to us eastern hunters, and two of our guys pulled the trigger too fast. One guy ended up with a 180, I ended up with a 140 5x6.
