Here is a pic of Thompson Temples Texas Hill Country Bighorn breeder (I took the picture). Its a hybrid that is Bighorn x Mouflon x Stumberg x Urial. His original sheep were Bighorn x European Mouflon. He added in the Stumbergs because they are so healthy...then the Urial to get the body size and horn mass. Look at this particular ram and some photos of Texas free range Bighorns to see how he's done. His stated goal is to develop a sheep that looks like a bighorn but is affordable for the average hunter to hunt. I cannot comment on his hunts only the rams.
