I shot! I got him right in the shoulders and spine. He went down and then started growling! Then he rolled behind a tree and we could still hear him growling so we jumped out of the blind and Lucas took the rifle and put one more shot in him (so he wouldn't roll any farther down the hill).
He's at lease 225 pounds! So Lucas gutted him and then we had the trek out. Lucas carried him up the 50 yards to the top of the saddle and then we pulled him down the hill.
