I saw him upwind of me in a thicket and grunted him in. He lost interest until I gave a tending grunt series and then he came in on a string to get downwind of me. I shot him at 100yards even. I've never seen this before but when I shot him, He jumped straight up in the air and did a backflip!!! Landing on his antlers the fall broke his neck and he didn't move again, except for the 3 or 4 leg twitches.
