Years ago in the 20s I believe, Nilgai were imported by the King Ranch in South Texas. They have done very well and are now fairly commonplace in deep South Texas. The first one I shot with a 30-06 180 NP behind the shoulder, knocked him down kicking. He got up and ran off with a small herd of about 30 of his kin. I watched him for about 2 miles and he never was recovered. At that time in the early 80s, they had multiplied to the point that they were competing with the whitetail deer, and the ranch was considering a cull hunt to thin the herd.A very bad freeze in 1983 as I recall thinned the herd so the cull was avoided. I shot a second bull, neck shot this time, and he fell in his tracks. The meat is excellent and there is plenty of it. Mine weighed over 600 pounds on the hoof. The King Ranch offers hunts on a commercial basis. I don't know what the charge is but it is a fascinating place. I hunt there frequently for quail.
