Private property hunting is quickly becoming the most consistent producer of big bulls in Wyoming sad to say. Units 58, 63/64, 61, 123, 7, & 78 and some others less promoted by Huntin Fool, Eastman's and the like are all producing the most consist number of big bulls but the catch is many of them come from the private land hunting. The public land units around Yellowstone historically produced big bulls in years when the weather pushed the bulls out of the Park. The wolves have done LOTS to change that. You may want to consider unit 60 as it is easier to draw. It is a general hunt but still produces good bulls in years when the snow comes. Unit 78 is a slam dunk for a big 350+ bull if you will pay the $5000 trepass/outfitting fee but the quality of the hunt leaves alot to be desired.
