Excellent! I've killed many a whistlepig with pistol and rifle, but never one with stick and string. Missed one at about 8 yards once when I was a kid while using my dad's recurve. The 'pig was under an old barn with his head sticking out of his hole and I barely shot over his head and stuck the old Bear Razorhead into a young tree just over his head about 2 inches. I had been working on gettin' a shot at him everyday for about a week when school was out for the summer. Got one shot and blew it. But it still was fun tryin'!
Nice accomplishment!
