There is some that run wild in the area I hunt and as stated above just like the other exotic animals they have all escaped from the high fence ranches. We don't see many and I have only had doe or very small males offer me a shot , we never shoot them with the hope we will get more in the area. It hasent worked for us I guess they just move on as the place I hunt has no high fence and in many areas no fence at all. I will ask around about some of bigger non high fence ranches and see if they would have enough to have a person hunt ( I'm sure it would not be cheap ) I know I haven't been much help but there are some free range Blackbuck around , I will say killing free range exotics is usually tougher than our whitetail deer..
