Mark, I shot the blackbuck in my taxidermist's back yard near Medina, TX. He has only 80 acres with a run-down barb wire cattle fence, so they're not often on his property, but they do cruise through every once in a while. I just lucked out. This year was the third year I've hunted with him and this was my first blackbuck there. He's not really commercial, though he has been looking to get a few more solid, trustworthy hunters. He does mostly taxidermy, but has started offering a few hog hunts, mostly I think because he likes to hunt pigs!
There was a little buck (ear-length) with this herd of does (about a dozen), but I saw nothing shootable. Besides, at $600, the bucks are out of my league. Honestly, he's mostly set up for hogs, but "leftover" blackbuck and axis from surrounding properties occasionally wander through. We bumped into both on this trip, but only had an opportunity at the blackbuck.
