I shot a 150 or so pound boar last year at around 325 yds. He was on the backside of dirt berm in a cutover road with his head down and all I could see was the top 3-4 inches of his shoulder. I had a good rest, known distance, so I figured I could squeak one in just over the top of the berm and clip his spine. I cut it a little too fine or slightly misjudged the distance because I just barely clipped the top of the berm and saw dirt fly through the scope. Pig cut a backflip, went to kicking and rolled over into the cutover. Figured he was DRT. Walked down there a couple hours later and black hair, a little blood and no pig. Got a pic about 2 weeks later in same general area of a black boar hog with a fist sized U-shaped chunk missing right above his shoulder. I'm positive that I just barely clipped the top of that berm, bullet mushroomed while still retaining velocity and just blew a hunk of meat out the top of his shoulder but not quite getting down into his spine. They are tough animals for sure. Shot'em in the head and you dont have to worry about it. Should've waited for him to raise his head but we kill every hog we see and I didnt want to take a chance of him getting out of the road and took the shot I had.
