I've been putting in for that area for the past several years. I'd look between Horse Gulch and Spring gulch on the southwest side of Petty Mountain. Also be realistic in your expectations. A 180" ram is on the upper end of what you'll find. A guy I know had a tag there a couple years ago, hunted hard and shot the biggest ram seen. Scored 179 and was 10 years old. Good Luck.
