I assume you are rifle hunting, and with the season only 14 days long for Muley bucks, you need to spend the entire season in the woods, so you need to be prepared for November weather.
You have already found an area that had a buck, so I would start there. If you haven't started scouting already, you are behind. In addition to your eyes, get cameras out in that area and as many others as you can to confirm what's there. Build some mock scrapes for attraction to your camera traps. I don't worry about trying to pattern their movements; I want to confirm the area has what I'm looking for. Once the rut hits any pattern they had is pretty much gone. Obviously, pick your hunting areas based on the most Does and if you see any Bucks on camera.
The biggest tip I have for you after you have done your part with scouting is perseverance. Don't ******* give up.
The Muley population is not what it used to be, thanks to predators, including hunters, who continue to shoot Muley Does even though there is no season for them in the Panhandle. Unfortunately, every year I find Does and Bucks that were killed and left once the hunter realizes they killed the wrong animal and doesn't want to get caught with it. It's even more disheartening when you see the number of animals seized at F&G check posts from illegal harvests, and now there is CWD in the area as well.
You're targeting an animal in the panhandle that does exist, but is few and far between. Good luck to you.
