buck I shot this evening

Came to the edge of my field right at dark. Had to scope him to see him standing there. He stood frozen for about five minutes....absolutely motionless. Couldn't tell if he had horns until I blew the grunt call a couple of times before he finally stepped out in the field. He came within about 25 yds. of my stand before I shot him straight on in the chest. Wouldn't turn broadside so I had to shoot him before he got any closer. I didn't see any old injuries that may of caused his rack to be messed up like that. Genetics maybe? Either way I was glad to get him. Weighed in at 232 lbs. Pic is big....sorry, don't know how to resize from phone.
